Simultaneous estimation of heat fluxes applied to the wall of a channel with turbulent flow using inverse analysis

The main purpose of this study is to estimate the step heat fluxes applied to the wall of a two-dimensional symmetric channel with turbulent flow. For inverse analysis, conjugate gradient method with adjoint problem is used. In order to calculate the flow field,   two equation model is used. In this study, adjoint problem is developed to conduct an inverse analysis of heat transfer in a channel turbulent fluid flow. The primary purpose is to find suitable number of sensors at each half of the channel’s wall and an appropriate space on the wall for locating the sensors. The innovate aspect of the study is to find out ideal length of the channel’s wall on which sensors are located.
