Numerical Modeling Of Continuous Flow Microwave Heating - Coupling Of High Frequency Electromagnetism With Fluid Flow And Heat Transfer, Deepti Salvi

LSU Doctoral Dissertations

This study focused on numerical and experimental investigation of continuous flow microwave heating. A numerical model was developed to predict the temperature of a liquid product heated in a continuous-flow focused microwave system by coupling electromagnetism, fluid flow, and heat transfer in two different software packages (ANSYS Multiphysics 9.0 and COMSOL Multiphysics 3.4). The temperature and energy distributions simulated in ANSYS were verified against other numerical studies published in the literature. Comparison of the simulated temperature in ANSYS with experimental data for salt water of two different salinities showed good agreement. To simulate the experimental conditions more accurately, a comprehensive …
