Abstract

The measurement of radiant heat flux in flame tube is usually non-contact, so various factors should be considered in the actual measurement process. In order to improve the accuracy of measuring radiant heat flux on the inner wall of the flame tube, a flame tube model was used as the research object in this paper. A high temperature gas radiant heat flux wind tunnel measurement system was established to measure the wall radiant heat flux under different combustion conditions. The results of the test and numerical simulation were compared, and the relative error between the revised test and numerical simulation results was kept between -38.89% and 32.54%.
