A THEORETICAL AND EXPERIMENTAL INVESTIGATION OF SMOOTH ICE AND WAVY ICE LAYERS IN LAMINAR AND TURBULENT-FLOW INSIDE AN ASYMMETRICALLY COOLED PARALLEL-PLATE CHANNEL

The present paper shows the adaption of the numerical model originally developed by Weigand and Beer [14] for calculating steady-state ice l ayers inside an asymmetrically cooled parallel-plate channel. The inve stigation shows the characteristics in ice formation behaviour due to asymmetrically cooled walls. Further, a simple analytical model is pre sented for calculating smooth ice layers in turbulent flow. The study is supported by own measurements of the freezing fronts inside an asym metrically cooled channel. A comparison between theoretical calculatio ns and measurements shows generally good agreement.
