Research of the problems of heat conduction in fluids

Abstract

In the fluid of the pipeline, the phenomena of heat convection, heat conduction, and radiation heat transfer occur between the pipeline and the outside world as well as between the pipeline and the inside. In the calculation of the relevant temperature and heat, we need to know the heat transfer coefficient, pipeline characteristic length, flow velocity, and other data to get the results. Based on previous research results, this paper will use Ansys software to explore the change law of heat transfer effect with various parameters. We can find that in the simulation, as the flow rate increases, the heating effect will become worse and worse.
