Abstract

The invention discloses a post-processing method for a temperature field image of fluid in a flow channel, computer equipment and a computer readable storage medium. According to the post-processing method for the temperature field image of the fluid in the flow channel, two high-speed cameras are used for capturing the light intensities of two fluorescent substances respectively, and the light intensities of the two fluorescent substances at the same temperature are compared, so that the influence of uneven distribution of incident laser is reduced, and the temperature field image of the fluid in the flow channel is obtained. By setting the steps of boundary recognition, background noise reduction, image matching, temperature calibration, temperature field reduction, median filtering and the like, the problems of low image position matching precision and non-uniform light intensity distribution of the two high-speed cameras can be improved, the influence of factors such as refractive index difference and camera background noise is eliminated, high-efficiency and high-precision processing of the temperature field image is further realized, and the image quality is improved. The calculation precision of the image post-processing method can be improved.

Description

technical field [0001] The invention relates to the technical field of fluid mechanics experiments, in particular to a post-processing method of a fluid temperature field image in a flow channel, a computer device and a computer-readable storage device. Background technique [0002] With the continuous increase of human demand for energy, the efficient use of energy is a necessary prerequisite to ensure the sustainable development of our country's economy. Heat exchangers are key equipment for energy transfer and conversion, so improving the heat exchange efficiency of heat exchangers is an important way to save energy. In order to improve the heat transfer efficiency of the heat exchanger, a lot of research has been carried out on the heat transfer characteristics of the heat exchanger. However, due to the limitations of the measurement technology and the complex flow channel structure of the heat exchanger, it is impossible to obtain the detailed temperature field distribu...
