Gas-dynamic heating in cavities under the influence of pressure pulsations at the entrance

  • 24 Accesses

Abstract

An investigation has been made of the gas-dynamic heating of gas in nearly closed cavities (tubes, channels, etc.) under the influence of given pressure pulsations (with and without a discrete component) at the entrance. The results are given of measurements of the wall temperature of the cavities and also the power of the gas-dynamic heating as a function of the relative cavity length 10< ln/dn < 300, the relative level of the pressure pulsations σ0/p < 0.5 at the entrance, and the magnitude of the static pressure in the range p = 2–10 kg/cm2. It was established that with increasing p and especially σ0/p the power of the gas-dynamic heating increases strongly.
