SURFACE PREPARATION METHOD FOR EXPERIMENTAL DETERMINATION OF HEAT-TRANSFER COEFFICIENT

摘要

The invention relates to processes for the thermal test, especially heat experimental research and may be used, e.g., when measuring the coefficient of heat transfer in the flow part of a gas turbine inventive method; Copper thermocouple mounted in cylinders that are mounted in pre-formed holes flush with the sample surface, m- applied to it a layer of electrical insulation, and on it - the electrically conductive layer. As the conductive layer, a mixture of heat-resistant varnish and pyrolytic carbon. 1 h. n. f ly-3-yl.
