Temperature and stress field modeling in accreted ice on the cylinder in a supercooled gas-drop flow

The thermal stresses in accreted ice due to conduction of change of phase heat releasing on the ice surface because of solidification of supercooled drops are investigated. Based on the test investigations of a model problem (for the ice slab in a form of cylindrical segment), it is shown that the local values of some components of stress tensor in the slab may exceed the ultimate strength (measured earlier in laboratory conditions) and eventually lead to spalling and cutting-off anew accreted layers by the flow. The obtained results testify to appropriateness of self-consistent approach for the problem as mutual investigations of both surface icing and stress propagation within growing ice slab simultaneously.
