Aluminum Composite materials are mainly used for the application of light weight material in many aspects, the main application is considered for the front and rear spools in automobile. Apart from automobile field it is also used in various structural application and valves of transportation. The Aluminum Composites is to increase the strength and life span of the components. Basically, Most of the Aluminum Alloy does not satisfactory wear resistance. The focus of this research paper is to select a suitable Aluminum Alloy and composition that compensates high strength, wear resistance, and self-lubricating property. It is noted that spools are manufactured by using stainless steel which are more weight when compared to Aluminum alloy. Aluminum Alloy is reinforced with the composite material Molybdenum-Di-Sulphide which has a low friction, very good self-lubrication system in it. In this work, influence of Molybdenum-Di-Sulphide (MoS2) is added to increase the performance of the spools using Aluminum Alloy-7075 was studied. Stir casting technique is used to fabricate the hybrid composite with AA7075 with Molybdenum-Di-Sulphide (MoS2) at varying weight fractions such as 3%, 6% and 9% for improving wear properties. The Mechanical characteristics and Wear characteristics are analyzed to prove the strength and life span of the material composition. The wear and friction tests yield good results at higher sliding speed, low load and high composition. The main motive of this project is to increase the wear resistance and life time of the spools.

Experimental investigations have been carried out with different types of inserts to enhance the heat transfer rate under turbulent flow of air in a pipe. Experimental data obtained using the different types of inserts for friction factor and Nusselt number, and an improvement in heat transfer rate had also recorded. Maximum enhancement in heat transfer is obtained by protruding the spiral-rectangle block inserts. The Performance Assessment Coefficient (PEC) has taken into account to analyze the increment of both the friction coefficient and Nusselt number with and without inserts with respect to flow and heat transfer. The outcome for PEC with different Reynolds number (Re) imply a real increase in Nusselt. The results for PEC with different Re indicate a true increase in the amount of Nusselt is up to 126 percent and the corresponding friction factor is 140 percent with the spiral-rectangle block inserts, in turn subsequent improvement in the heat transfer rate.

Now a days everyone has a refrigerator in their home for the purpose to store foods, medicines and eatables etc. Some foods based on its property we can directly use after we taken out from the refrigerator. But under some conditions we can't use the products directly from the refrigerator so we need to bring the product into room temperature for better usage. If not done so some medical issues are being raised so to avoid this, we have a solution smart container in refrigerator which does the de-cooling in the refrigerator itself no need to keep it in temperature and this is a remotely operable from anywhere using IOT. This must be done in an efficient manner and the approach to solve this aspect is discussed further. The following we made cad design for the smart container. Before manufacturing we need the visual proof whether it is suitable are not to our daily household use the factor considered is the refrigerator temperature and the environmental temperature. Under this condition we are going to calculate the time. How long it will take to cool the container. The whole analysis is made in computational manner using the ANSYS software. The final verified result shows the time taken to cool the container is 14 seconds. The analysis result for time taken to de cool the container is 19.5 sec. According to the ANSYS report 20 iterations are need to make the calculation of the time. This will give the better and expected results. [ABSTRACT FROM AUTHOR]

It is estimated that 40 – 50% of the total heat produced within the body is released through the head. This dissipated heat from our head gets trapped inside the helmet resulting in increased internal temperature along with the addition of external heat from the surrounding, making it uncomfortable for the user. This work discloses on the designing and fabrication of a cooling system implemented in a motorbike helmet with the use of PCM(Phase Change Material) and mechanically constructed Fins fixed onto the shell surface, to prolong the thermal comfort period compared to a normal helmet. The PCM material is packed in pouches and placed between the Expanded Polystyrene Styrofoam(EPS) and Outer Shell of the helmet. As heat is generated inside the helmet, the PCM absorbs the heat, which is then transferred to the fins. Fins are provided to help in a faster heat transfer rate from the helmet to the surrounding. This hence helps in maintaining the internal temperature for the user by preventing the excess heat from accumulating inside the helmet and thereby removing a major cause of discomfort to the rider.

Electricity is one of the key issues for our day-to-day activities in today's technology-driven world. The fact that the renewable energy sources are depleting at a lightning-fast rate is clear to us all. Solar wind hybrid system combines solar power stations and wind power plants. Solar panel is used for power generation. PV panel The Peltier module is used to improve PV panel efficiency and performance. Certain PV panels are used to compare the performance of both solar panels, without the Peltier module. The wind's kinetic energy is transformed through the wind turbine into mechanical energy. Dc motor rotates to produce the electrical energy which is transferred to a battery through dc to dc boost converter to increase the voltage output of the wind turbine. The power generated from all the three systems will be stored into the battery through the regulators and then it will be sent to the invertor for use in AC loads. [ABSTRACT FROM AUTHOR]

This work is experimentally testing a combination of thermal conductivity and viscosity characteristics to achieve optimal heat transfer utilizing Silicon Carbide (SiC) Therminol 55 as Nanofluid. Recent experiments have shown that Nano-fluids have outstanding properties that render them efficient in many thermal transmission applications in comparison to basic fluids. SiC-Therminol 55 Nano-fluid is synthesized at varying amounts (0.1 per cent to 0.3 per cent) by the production of SiC Nano-Particles of length (80 nm) in therminol 55. Temperature and viscosity were calculated using kd2 Analyzer and Fenske Viscometer at a temperature range. The experimental effect, demonstrated by the highest thermal conductivity, raises volume concentration and decre ases viscosity. At the end of the process, theoretical models are developed for the analysis of the propensity of the Nanofluid to well-established H-C models. [ABSTRACT FROM AUTHOR]

This paper primarily focuses on improving the efficiency of a helical spiral shaped turbine. The efficiency of the system proposed encompassed with helical spiral shaped turbine, is improved by heating the air that passes through the capsule containing the turbine. Further, the capsule is shaped like a nozzle in order to increase the pressure of the inlet air. By increasing the turbine inlet temperature, the overall efficiency of the turbine/system can be improved by a large margin. This heated air not only has improved efficiency benefits but also can have a greater benefit on the revenue of the manufacturers. The system proposed uses the ocean thermal, solar to preheat the inlet air. This is done to exploit the available energy from the ocean and solar to maximize the output. A new float which is part of the system has been designed in order to pressurize the air coming out from the solar collector using wave energy. This particular float has a dead weight that helps to provide more down force even during low waves. At the time of erratic wave conditions, the dead weight is forced to position itself to the mean position using an electro-magnet. [ABSTRACT FROM AUTHOR]

Drying of agricultural, food and other products is a valuable process used to increase the usefulness of the product during the non-seasonal periods. The need for agricultural and food products is always increasing because of the increase in population. Hence meeting the need in food requirement is a threat and it can be achieved by increasing the cultivation and also by reducing the wastage of crop, fruits, grains, food products, etc. The wastage of products can be avoided by using preservation processes like conventional and hybrid drying technologies. Also optimizing these technologies is very much important to improve the quality of dried products in a lesser time and at lower costs. In this review, various types of drying methods, the technological improvements in this field and the research work performed using solar and other drying processes are presented.
