The rate of heat transfer is very sensitive to the quantity of water in the two-phase mixture and is 14.9 times greater than that for single-phase flow at a Re of 4.8x10 to the 4th power. The film coefficient of heat transfer increases with Re but the amount of water in the boundary layer is the dominating factor. The local film heat transfer coefficient in two-phase flow is greatest at the stagnation point it decreases with distance away from the leading edge and becomes essentially equal to the single-phase value at an angle where the liquid film separates from the cylinder.
