Heat Flux Control in Non-stationary Conditions for Industry Applications

For industrial control systems, the advantage of directly measuring the heat flux is that, the controlling the parameters of an object at a temperature, only the consequences of thermal action are recorded. The determination of the heat flux can detect a disturbing effect at the initial stage, predict its state and timely correct the mode of operation of the object. The purpose of the work is to provide control of the heat flux in non-stationary conditions with the use of heat flux sensors and to determine the requirements for industrial measurement equipment. From the theoretical and experimental results follows that the use of a modified sensor always gives a gain in time compared with a standard sensor. For study of non-stationary thermal conditions established requirements for the information-measuring system. Given a practical application example of surface heat flux measurements in non-stationary conditions for the control in the flight conditions of the thermal load on elements of the launch vehicle construction.
