Helium at a free stream temperature of T∞ = 25°C is in parallel flow over a flat plate of length L = 3 m and temperature Ts = 85°C. However, obstacles placed in the flow intensify mixing with increasing distance x from the leading edge, and the spatial variation of temperatures measured in the boundary layer is correlated by an expression of the form T(°C) = 25 + 60 exp (−600xy), where x and y are in meters
