Design and fabrication of convergent exhaust gas calorimeter

Abstract

The exhaust gas calorimeter is a heat exchanger to improve the heat transfer rate and limits the scattering of exhaust gases. In this study reduction in the amount of heat through emission is been identified and related to the existing model to get comparatively better results. Various Calorimeter design and testing has been done using analytical software. Compared between to get better results than existing one. After modification in design, the modified calorimeter has been fabricated. It demonstrates that the total heat transfer rate is higher and the heat transfer rate per unit area is greater than the current rate. Finally, we calculated and experimentally verified that the rate of heat transfer and the total rate of heat transfer was more efficient than the existing one and in this modified design of exhaust gas calorimeter it is observed that the density of materials increases hot gases is been reduced by elevating the temperature of these gases which leads to limiting scattering of gases like NOx, CO (Nitrogen oxides, Carbon Mono oxide), etc., scattering directly into the atmosphere.
