FINITE ELEMENT (FE) ANALYSIS AND OPTIMIZATION OF CONCENTRIC HEATER

The effectiveness of heat exchanger shows its performance. Shell and tube heat exchanger is selected from previous research paper. Its effectiveness is calculated by mathematical modeling. It is replaced by triple concentric tube heat exchanger with same input parameters and effectiveness is calculated by mathematical modeling. Three controlling parameters LDO inlet temp, Crude inlet temp and mass flow rate of crude are selected. L-9 array is formed with three levels of variables. Analysis is carried out for nine experiments. Optimize these controlling parameters. ANOVA is carried out to find the percentage contribution of each controlling parameter.
