Performance Evaluation of a Respirator Vortex Cooling Device

Performance Evaluation of a Ranque-Hilsch Vortex Tube with Optimum Geometrical Dimensions

 A brass Vortex Tube (VT) with interchangeable parts is used to determine the optimum cold end orifice diameter, main tube length and diameter. Experim...

Study of the performance of a solar adsorption cooling system

This article presents a transient model of a solar adsorption cooling system. A computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. This program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of r...

Modeling the Cooling Performance of Vortex Tube Using a Genetic Algorithm-based Artificial Neural Network

In this study, artificial neural networks have been used to model the effects of four important parameters consist of the ratio of the length to diameter, the ratio of the cold outlet diameter to the tube diameter, inlet pressure, and cold mass fraction on the cooling performance of counter flow vortex tube. In this approach, experimental data have been used to train and validate the neural net...

Respirator performance rating tables for nontemperate environments.

Respirator performance rating tables have been constructed for hot, humid (29 degrees C, 95% RH); hot, dry (49 degrees C, 30% RH); and cold, dry (-32 degrees C, 70% RH) conditions. These tables convey expected wearer performance percentages compared to unmasked workers for various mask elements and work rates. The hot, humid condition was found to be the most severe overall. Many table entries ...
