摘要:
Further experiments on cyclic, unsteady, transonic flow with heat addition are described. The heat addition is produced by condensation by homogeneous nucleation of water vapor or ethanol in the throat region of a Laval nozzle. Different carrier gases are used and frequencies of pressure fluctuations up to 22 kHz are found. Terms in a dimensional analysis that had previously not been investigated were studied. The new terms included different Damkohler parameters and the ratio of the specific heats. Under certain conditions condensation at M<I was observed. A qualitative description of the process and estimates of the frequency yielded satisfactory results.
