Abstract:
An analytical and numerical study of protective properties of hot-air screens is performed for a plane wave with a triangular profile. The reduction of the shock-wave pressure behind the screen is only observed at temperatures higher a certain critical value; at lower temperatures, the pressure is higher than that in a shock wave traveling in an isothermal gas. With allowance for real properties of air, an analytical relation between the critical temperature of the hot screen and the incident-wave intensity is obtained.
