在积冰生长模拟过程中引入了冻结系数的概念,使得能够模拟计算出不同积冰参数下的不同冰型。以NACA0012翼型为对象,计算不同条件下的积冰情况,发现温度是引起冰型变化的主要因素,其他积冰参数(气流速度、液态水含量、液滴直径)对积冰量有影响,但对冰型影响较小。
The concept of freezing coefficient was introduced during ice accretion simulations to enable the different ice formations under different ice accretion parameters to be simulated. Taking NACA0012 airfoil as an example, the ice accretion under different conditions was calculated and it was found that temperature was the main factor causing ice type change. Other ice accretion parameters (air velocity, liquid water content and droplet diameter) But less impact on the ice.
