DEVICE FOR MEASURING HEAT EXCHANGE CHARACTERISTICS IN ROTATING CHANNELS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: cool gas is pumped into measuring vessel 8 of the device through cool air supply channel 6. Shaft 3, rotor 4 and tested channel 5, channels 6 and 7 for supplying cool and hot gases and distributing valve 9 are driven into rotation. Tested channel 5 is heated by hot gas which passes through channel 7. When necessary temperature of tested channel 5 is achieved, supply of hot gas is finished and cool air is fed for cooling working part of tested channel 5 from measuring vessel 8 through channel 6 and distributing valve 9. EFFECT: improved precision of measurement. 1 dwg
