| Abstract: | The paper introduces numerical methods for calculation of aircraft icing,including the flow field calculation,equation of supercooled water droplets and icy volume calculation,and presents two models of ice growth.For wind tunnel tests,measurements of droplet diameter and liquid water content are difficult and important.Measurement methods of the two icing parameters mentioned above are summed up.Two conventional icing scaling methods are given,and the design of mixed scaling model is brifely introduced. |
