77-30569/256283 Experimental survey of heat transfer characteristics in inner channels of turbomachine cooling systems when using thermochromic liquid crystals
Engineering Education # 01, January 2012
The non-stationary method with the usage of thermochromic liquid crystals is one of the modern approaches to the heat transfer characteristics evaluation. It allows calculating the local heat transfer coefficients distribution in the inner channels of turbomachine cooling systems. The structural scheme and technical implementation of experimental stand are shown. The process of data collection and processing for computing of local heat transfer coefficients was described.
77-30569/253757 Space radiant heat exchanger for heat elimination
Engineering Education # 10, October 2011
Coolant heat exchanger intended for heat removal by radiation into an open space is considered. The settlement program for numerical calculating the fin-type heat exchanger is described. Various emitter panel constructions are analyzed. Identical versions of radiant panels with neon and hydrogen as the heat carrier are compared. Comparative characteristics data of the matrix radiator for heat carriers with different combination of materials and pipes edges are shown. Advantages of liquid metal heat carrier of the intermediate circuit are underlined. Main features and packaging problems of power installation of a space plant are named. Version of the radiator design with a phased scheme of its opening in orbit is proposed
