AIR INTAKE IN THE TRANSIENT REGIME OF RAREFIED GAS FLOW
摘要
The gas flow in an air intake was numerically studied by the Direct Simulation Monte Carlo method in the free-molecular and transient flow regime for a finite Knudsen number without gas offtake from the collector. In conditions when the external flow is free-molecular, there is a marked difference inside the air intake that is associated with an increase in the gas density in the collector. For intake in a cylindrical tube, the dependence of the maximum gas density in the collector and the flow field on the relative length of the tube, the velocity ratio in the oncoming stream, and the temperature factor were studied. We report that, in the transition phase, the dependence of the relative value of the maximum gas density in the collector on the Knudsen number is nonmonotonic.
