Abstract: Experimental results on heat transfer of straight pipe flow with internal freezing of water are presented. This study covers the range of ReD=200-10000, T*w=3-10 and L/D=20-80. The Pr number is fixed to 11.2. Referring to the steady pressure drop data and observation of internal ice layers, data of mean Nusselt number at steady state are categorized into four regions: L-region (low ReD and smooth ice surface), S-region (low ReD and ice layer with a step), T-region (high ReD and very thin ice layer) and I-region (intermediate region between L-and T-region or intermediate region between S-and T-region). Experimental formulae of Num for each region are presented. Transient behaviors of Num, pressure drop and the location of the step on the ice surface are also shown.
