METHOD FOR SIMULATING ICE ACCRETION AROUND AN AIR INTAKE

摘要

Disclosed is an icing simulation method for the surface of an air inlet. The icing simulation method for the surface of the air inlet according to the present invention comprises a step for defining the grid topology and the boundary condition of an icing wind tunnel test unit for modeling the air inlet and the air inflow of the air inlet; a step for setting the size of the icing wind tunnel test unit; a step for setting the speed, the temperature, and the pressure of air of the air inlet as predetermined values and analyzing a flow field of the air inlet by calculating surface pressure distribution and surface speed distribution of the surrounding surface of the air inlet; a step for calculating the accumulation ratio of droplet accumulated on the surrounding surface of the air inlet according to predetermined droplet amount and a predetermined droplet size based on the calculated surface pressure distribution and the surface speed distribution; and a step for analyzing icing proliferation on the surrounding surface of the air inlet by using the accumulation ratio of the droplet.
