Abstract: In the present research work, thermoelectric generation is numerically solved for waste heat recovery based hot junction point. All experiments are designed as per DOE methodology 'Taguchi method'. In the first part of this study, CFD simulation is performed for waste heat exchanger run on IC engine exhaust gas. Total nine cases are designed for this task using the Taguchi method. Wall temperature is the response variable for CFD work. In the second part, CFD based results are carried forward to FEM simulation which was conducted for thermoelectric generation numerical work. The same nine cases are used for this task also. It is found that the number of fins used in WHRS is not the prime factor, but mass flow rate is the main factor for this study. S/N ratio and ANOVA analysis are performed for wall temperature and current density of TEG system.
Keywords: thermoelectric generator; CFD simulation; Taguchi method; linear regression model equation; ANOVA analysis.
