CFD-based fluid calculation model selection and field analysis for small reactors

Abstract

To improve the accuracy of reactor design, this article uses k-ε, DES, LES, and SST four methods to compare the simulation results of the velocity field in the blade area, turbulence intensity, and velocity distribution of the fluid in the reactor, and predict the appropriate field model of the reactor calculation. Therefore, the calculation process is more suitable for the SST model of small reactors.
