Abstract

The ablation rate of frozen mixtures of water or wax with finely divided solids subjected to a turbulent axisymmetric water jet was investigated both experimentally and theoretically. The range of the water jet Reynolds number was 8700–29300 and the jet temperature varied between 22 and 60°C. The solids used were very fine kaolinite clay, titanium oxide and aluminium powder. The type of solids and their concentration were found to affect the ablation rate of ice‐solids and wax‐solids mixtures. This is mainly due to changes in the physical properties of the melt layer of the water‐solids or wax‐solids mixtures which forms between the impinging jet and the frozen mixtures.
