摘要：Abstract.Taking the uniformity of the flow field and pressure field on the tube plate as a measure, this paper designs four kinds of circular distribution plates which is installed at the chamber to improve fluid field distribution. The simulation on CFD results show that the circular distribution plate can improve the flow field distribution and pressure field distribution obviously on the tube plate. Under the condition of a certain opening rate, when the diameter ratio of the circular plate to the tube plate is about 0.5, the distribution of the flow field and the pressure are more uniform.The research results have a certain guiding significance for the selection and design of the circular distribution plate in the inlet chamber.
