CHARACTERISTICS OF FLOW OF WATER-VAPOR WITH HEATING BY SHOCK-WAVES AND COOLING IN SUPERSONIC NOZZLES

A study is made of the condensation of water vapor on the channel wall s of a shock tube in regard to its effect on the formation of the para meters of the flow behind shock waves generated in the tube. The effec t of condensation on flow in the nozzle is also studied. An examinatio n is made of the effect of the absorbing condensate film on measuremen ts of the absorption index of H2O. Experimental values are obtained fo r the Reynold's number corresponding to the transition from a laminar boundary layer to a turbulent boundary layer behind the incident shock wave during flow of the water vapor in the shock tube.
