Velocity and temperature profiles were computed for developing turbulent flow in a square duct with constant wall temperature, constant wall heat flux or asymmetric heating. The computations utilized an explicit numerical differencing scheme and an algebraic closure model based upon a three-dimensional mixing length. The computed local and fully-developed shear stresses and heat transfer are shown to be in good agreement with measured data and with predictions using the k–ε closure model.
