T1 Heat and Mass Transfer and Friction in Injection to a Supersonic Region of the Laval Nozzle JF Heat Transfer Research JO HTR YR 2000 FD 2000-11-01 VO 31 IS 6-8 SP 388 OP 398 AB Experimental and calculation-theoretical studies on the determination of a flow structure in injection of a foreign gas to a supersonic region of the nozzle are conducted in order to find the possibility of thermal protection of a wall and to reduce losses of specific characteristics due to injection. Experiments are performed on a model engine. Calculation studies are conducted on the basis of a theoretical-calculation method involving a two-scale four-parameter model of turbulence with account for density fluctuations in all equations.
