210. Integration of winglet type vortex generators in finned-tube heat exchangers for a sizeable capacity augmentation

Author

da Silva, Lucas FM, Adams, Robert D, Sato, Chiaki, Dilger, Klaus, Arora, Amit, and Subbarao, PMV

Abstract

Compact size of the heat exchange module is an important design consideration in majority of the thermal management systems. Using winglet type vortex generators, a sizeable improvement in the compactness of a widely used finned-tube array is attempted through this study. Since the degree of thermal augmentation changes with the generators’ position, around the tubes, this 3D comprehensive computational investigation aims to develop phenomenological correlations for the positional optimization, which are applicable over a wide range of operating conditions. Besides, this article is dedicated to understanding different aspects of the augmentation mechanism, including the tube-wake management and the performance improvement caused by the best design(s). Based on a parametric investigation, designs that are best suited for obtaining a sizeable performance augmentation of the system are identified. Furthermore, a critical assessment of the best designs is carried out to evaluate their impact on the heat transfer from wake-affected surfaces, both fins and tubes. It is encouraging to observe that the wake-affected surfaces also experience sizeable thermal augmentation, which increases further with the Reynolds number. While the total fin surface experiences a highest Colburn j-factor augmentation of 53.6%, the wake-affected fin undergoes 205.1% rise. An evident manifestation of the augmented Colburn j-factor is the reformed temperature distribution, which bears lower values all over the fins.

213. Novel CFD-DEM approach for analyzing spherical and non-spherical shape particles in spouted fluidized bed.

Abstract

The spouted fluidized bed process is a multiphase heat and mass transfer flow. The process requires effective solid-gas and solid-solid interaction. Various numerical models have been developed to understand and optimize these interactions. However, most of these models have used spherical particle definition, whereas the actual particles are non-spherical. Here we present coupled Computational Fluid Dynamics(CFD) and Discrete Element Method(DEM) based model to analyze the fluidized bed process for non-spherical particles (Faceted cylinder). The model results are validated with experimental results for spherical particles. The model is further used to understand mixing during the process as a function of non-spherical particle geometry. Aspect ratio and corner count were the geometrical input parameters for faceted cylinder-shaped particles. Transient plots for bubble diameter and bed height for spouted fluidized beds were created for all cases. The bubble diameter and bed height values were much lower for faceted cylinder particles than for spherical particles. For non-spherical particles, the increased number of corners was a crucial factor that brought the outcomes closer to those of spherical-shaped particles. The aspect ratio values increased, and the bubble diameter shrank as a result of more resistance to particle movement. The results would be of great use to correctly simulate non- spherical particles based fluidized bed process and optimize various process parameters. The coupled CFD-DEM method was used to analyze the hydrodynamics of spouted fluidized beds for spherical and faceted cylinder particles by plotting bubble diameter and bed height Analysis showed that non-sphericity brought resistance to the movement of particles inside the chamber, affecting efficient mixing between phases. The increased number of corners for non-spherical particles became the dominating parameter compared to aspect ratio for resembling results of fluidized beds closer to spherical-shaped particles. Post-processing of the results by division tagging showed that non-spherical particles have less tendency to mix than spherical particles. [ABSTRACT FROM AUTHOR]

214. Experimental studies on natural bank type heating/cooling energy saving Air conditioning system.

Author

Goyal, Vaishali, Asati, Arun Kumar, Garg, Rajeev Kumar, and Arora, Amit

Abstract

The present study reports air-based novel energy saving compact bank type earth air heat exchanger system (EAHE) (having only 25m2 area) fabricated from Polyvinylchloride pipes of nominal diameter 0.203 mm (8 inches) for inlet and outlet headers and main pipes and 0.150 mm (6 inches nominal diameter) for branched pipes, which is installed in Shaheed Bhagat Singh State University, Ferozepur in Punjab state, India (North West border area of India) and studied for the duration from April to August 2021 using the full factorial design with four inlet variables at multilevel to find a model equation between inlet and outlet variables, i.e., heat exchanger effectiveness and achieved temperature difference. An induced airflow mode has been used to provide near-uniform flow through all corresponding pipes of symmetrical-shaped earth air heat exchangers. The values of Dry bulb temperature (DBT) and wet bulb temperature (WBT) have been measured for air inlet, for air outlet, as well as for ambient air using resistance temperature detectors (RTD) installed at the requisite locations. Earth's undisturbed temperature (EUT) was also noted by installing RTD at a depth of 2 m, and the average measured value of EUT is found to be 28.5°C. The current system has imparted the temperature difference variation from 0.4 oC to 9.4 oC, and the effectiveness varied from 0.16 to 0.82 during the whole season. This system could give a cooling potential of 0.0523 kJ/s to 1.587 kJ/s using a mass flow rate of 0.163 kg/s.Experiments have been designed methodically to apply the full factorial technique. Most favorable parameters have been found for hot and dry and hot and humid weather. The current study is novel in terms of significantly improving the effectiveness of EAHE and addressing the central issue of space limitation in urban areas. [ABSTRACT FROM AUTHOR]
