Heat exchanger  

BACKGROUND

Pasteurization is one of the most fundamental yet complex thermal operations to ensure microbial safety. It is widely applicable in the food industry as well as taught in food processing/engineering courses across the globe. A tube-in-tube heat exchanger (HX) is commonly employed for the pasteurization of liquid products. Successful pasteurization is dependent upon multiple factors, such as heat transfer parameters, the direction of hot and cold fluids, velocities of fluids, length of heat exchanger, thermophysical properties of fluids, etc. Thus, it is crucial and challenging to integrate theoretical aspects of transport processes together for an enhanced classroom learning experience.  Therefore, we put forth a computer-based Multiphysics App, that can provide students with a spatial and temporal understanding of the pasteurization process in tube-in-tube heat exchangers. In order to fabricate the HX model, orange juice has been used as a sample food product.
