Exhaust heat recovery heat exchanger of gasoline engine

Abstract In this chapter, computational method has been used for exhaust energy recovery of internal combustion engine by means of double pipe heat exchanger. Both hydrothermal and entropy analysis are presented. Hot gas and H2O–CuO nanofluid are considered as working fluids. FVM is utilized to find the roles of Reynolds number, number of revolution on hydrothermal treatment. Suitable correlations for entropy components are extracted according to obtained data. Results reveal that S g e n , t h decreases with enhancement of N and Re. S g e n , f augments with increase of N.
