The effects of maximum density near 4C on steady-state, two dimensional ice formation around an isothermally cooled horizontal cylinder in a quiescent water bath are studied experimentally for ambient water temperature T {infinity} = 1.9 to 18.0C and cylinder surface temperature T{sub w} = {minus}20.0 to {minus}16.2C. The stagnation point Nusselt number, local heat transfer coefficient, and average Nusselt number behavior at the ice-water interface are studied using such parameters as ambient temperature, Rayleigh number, and a modified Grashof number Gr{sub d}*. The temperature field in the ice layer is determined from the measured ice profiles by a point-matching method using a series solution of the Laplace equation in the ice. Flow visualization photographs of the flow patterns near the ice surface are presented.
