Today, the content compiled by Xiaobian is the numerical simulation of plate heat exchangers. Friends who want to know will follow the introduction of Xiaobian to take a look.
When gas-liquid two-phase flow flows in a plate heat exchanger, the flow variable is increased. Moreover, the relative velocity of the gas-liquid two-phase, the volume fraction of the gas phase, and other physical property parameters have great randomness, so the flow and heat transfer situation is very complicated. There is great randomness. Many scholars are based on existing gas-liquid two-phase flow theory. Divides research methods into two categories:
(1) The Euler-Lagrangian model, which uses the liquid phase as a continuous phase and the gas phase as a discrete phase, is suitable for the study of particle dynamics and particle orbital models;
(2) Treat both gas-liquid phases as continuous phases with continuous velocity and temperature distributions in space.
Different turbulence models are established according to different physical models. The continuous medium model considers the particle phase as a continuous medium that penetrates into the fluid. The fluid and particles fill the flow field at the same time. For the motion, the Euler-Euler model is used to process the two-phase motion. So it can be called the Euler method. For different continuous media. Each phase has independent mass, momentum, and energy conservation equations, and these equations are coupled by interphase interaction.
I hope that the introduction of the plate heat exchanger above will bring you some help.
