| Outline of Final Research Achievements |
We apply optimal control theory in order to achieve dissimilarity between wall friction and wall heat flux in internal flows. First, we consider ideal wall blowing/suction as a control input and the optimization of its spatio-temporal distribution is conducted. By analyzing the obtained optimal control input, we develop a simple predetermined control strategy for dissimilar heat transfer enhancement. In addition, we clarify the scaling of the optimal traveling wave-like control input. Next, we extend the above approach to the shape optimization of complex heat transfer surfaces. By representing heat transfer surface with a level-set function, its spatial distribution is optimized so as to minimize a prescribed cost functional. It is demonstrated that the proposed scheme is promising in optimizing complex interfaces in a wide variety of engineering applications.
