In this paper, mumerical and experimental investigation on forced convection heat transfer in a vertical duct with asymetric side-wall cooling below the fusion temperature has been carried out. The cooling plate wall temperature was -10deg. and inlet water temperature was constant at 10deg. The Reynolds number was varied from 200 to 800. We discuss how the velocity of forced laminar flow influences the response of time-dependent average ice-layer formation. Next the velocity was varied periodically with several different conditions of amplitude and frequency. The experimental results agreed well with the analytical calculations. For the prediction of the steady-state average ice-layer thickness a simple one-dimensional numerical model which is based on the boundary layer equations was proposed for engineering.
