Nozzle contours for minimum particle-lag loss [PDF]
, 1963 The flow of a gas-particle mixture through a rocket nozzle is analyzed under the approximation that the particle slip velocity is small compared with the average mixture velocity, using one-dimensional gasdynamics, the Stokes drag law, and corresponding ...

Symposium - International Astronomical Union, 1996 The cosmic nozzle is a channel with flowing hot gas in a system containing the following components: stars, a hydrostatic gaseous corona and a cavity with hot gas in the central part of the system. In the quasi one-dimension approximation, the following solution of the cosmic nozzle problem about cosmic nozzle was obtained Here (ν,ω, T, σ) are the ...

Similarity Law on Shedding Frequency of Cavitation Cloud Induced by a Cavitating Jet
Journal of Fluid Science and Technology, 2012 In order to clarify the mechanism of cavitation cloud shedding, the shedding frequencies of cavitation clouds were investigated by high-speed observations and image analysis. The results indicate that the shedding frequency follows the similarity law for
