Nonsteady method for measuring heat fluxes
Abstract
The unsteady-state method for measuring heat fluxes by the probe mounted in the nozzle throat is proposed to determine heat transfer between a probe surface and a gas medium as well as to find a change in thermophysical properties of a probe depending on a temperature. As a result of solving the non-linear heat conduction equation, the time change of the heat flux is determined by a temperature measured in time at a fixed distance from the probe surface.
