I am studying the effect of inserting perforated baffles inside a rectangular channel on heat transfer enhancement and flow friction features inside the channel. The upper and lower surfaces of the channel are thermally active while the side walls are considered adiabatic. The study is a numerical one using a Fluent three-dimensional model. I need to determine the thermal boundary layer thickness on the thermally active walls (upper and lower walls) where the baffles are mounted on these walls in a staggered fashion. I want to analyze the effect of baffles' presence on the development of thermal boundary layer and heat transfer augmentation as well. Thus, how could I measure the thermal boundary layer thickness using ANSYS Fluent program?
