Abstract

High density storage solution such as dynamic flow pallet racks is accumulation racking system recommended for great amounts of good with only few different storage units. Palletized units are stored into deep tunnels not accessible by forklifts for handling operations. These systems have overall objective to increase the cube utilization and to reduce the handling costs. In this case selectivity is sacrificed but the storage density is outstanding. Forklift brings storage unit to and from the racking. Movement of the storage units within racking structure has been achieved through gravity or some other force. Warehouses in food and pharmaceutical industry are the ones who have benefit more from the installation of these solutions. This paper presents introduction of dynamic rack solution. Technical analyses and solution based on investor request to speed-up and reduce cost of handling process will be done. [ABSTRACT FROM AUTHOR]

Abstract

This paper examines the possibilities for improving the integration characteristics of active charcoal by using finite elements method simulation. Two different modes were considered separately: the period of active adsorption, when the activity of radon in charcoal increases, and the saturation period, when the activity is constant. The timewhen saturation begins depends on the thickness of the layer of charcoal. It was found that the peak amortization is 24 h in active adsorption and 36 h in saturation period for examined charcoal and canister. [ABSTRACT FROM AUTHOR]

Abstract

Smoothed particle hydrodynamics (SPH) and the finite element method (FEM) are often combined with the scope to model the interaction between structures and the surrounding fluids (FSI). There is the case, for instance, of aircrafts crashing on water or speedboats slamming into waves. Due to the high computational complexity, the influence of air is often neglected, limiting the analysis to the interaction between structure and water. On the contrary, this work aims to specifically investigate the effect of air when merged inside the fluid&ndash, structure interaction (FSI) computational models. Measures from experiments were used as a basis to validate estimations comparing results from models that include or exclude the presence of air. Outcomes generally showed a great correlation between simulation and experiments, with marginal differences in terms of accelerations, especially during the first phase of impact and considering the presence of air in the model.
