| Research Abstract |
Enhancing heat and mass transfer with suppressing pressure drop is fundamentallyimportant for improving efficiencies of energy devicetsh.eIpnresent study, we revisitthe governing equations and boundary conditions for momentum and scalar transfer in order to clarify possible scenarios for dissimilar heat transfer enhancement in a fullydeveloped channel flow. Based on these knowledgef,irswtedemonstrate simultaneousachievement of friction drag reduction and heat transfer enhancement by determining the spatio-temporal distribuion of wall blowing/suction based on the optimal control theory. We also show that the resultant optimal cionpturtol exhibits a traveling w-alivkeeproperty in the streamwise direction. We eventually propose a si-mlpoloep for dissimilar heat transfer enhancement.ospternategy
