Description
Thermoelastic theory is used to calculate thermal stresses in ice crystals of idealized shapes when a small area on one surface is warmed to 0°C, in simulation of riming of the crystal by a cloud droplet. It is shown that a typical riming event involving a 20 μm diameter droplet impinging on a 500 μm plate or column would need to occur at a temperature colder than −35°C before fracture could be expected. For a given ice crystal size, the thermal stresses increase with droplet diameter, and thin...[Show more]
