ANALYSIS OF THE APPLICATION OF TRENCH HOLE RELIEFS IN THE DEVELOPMENT OF A UNIFORM PLATE-FIN HEAT EXCHANGERS MODERN ROCKET ENGINES
Brief overview of results of theoretical and experimental studies of heat exchange intensification by of artificial roughness in form of hole reliefs is presented. Evaluation of changes of thermal and hydraulic parameters of helium at use of parallel trench holes on bottom of channel of walls of heat exchangers of RD193 and RD175 developed engines.
