摘要

研究考虑了一种基于记录飞行器模型内表面薄壁涂层荧光的全景温度测量方法。该方法可用于研究高焓短时风洞的光学污染流。气动模型表面的温度和热通量是通过将温度测量结果与飞行器周围流动的邻接问题的数值解结合起来而得到的。这种方法的实际应用是在 ITAM SB RAS 的热风隧道中进行的。

Application of optical visualization of the inner surface temperature of a thin-walled model in the flow in a hotshot wind tunnel

A method of panoramic temperature measurement based on registering the fluorescence of thin-walled coatings on the inner surface of a flying vehicle model is considered. The method allows investigations in optically polluted flows of high-enthalpy short-duration wind tunnels. The temperature and heat fluxes on the aerodynamic model surface are retrieved by means of combining the results of temperature measurements with the numerical solution of an adjoint problem of the flow around the flying vehicle. Implementation of this method in practice is performed in the flow of a hotshot wind tunnel based at ITAM SB RAS.

期刊介绍： The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
