IMPINGEMENT OF CLOUD DROPLETS ON AERODYNAMIC BODIES ASnAFFECTED BY COMPRESSIBILITY OF AIR FLOW AROUND THE BODY

摘要

The trajectories of water droplets in a compressible-air flow field around a cylinder were computed with a mechanical analog. The results of the calculations at approximately the flight critical Mach number were compared with calculations of trajectories in an incompressible flow field. For a cylinder, the effect of compressibility of the air on the droplet trajectories was negligible up to the flight critical Mach number. The results obtained with the cylinder were extended to airfoils. This extension is possible because the incompressible flow fields of both cylinders and airfoils are similarly altered by compressibility.
