Abstract

Aiming at the problem of wastewater treatment system, the Navier-Stokes equations of incompressible flow were calculated by one-direction staggered grid method. The reason and inhibiting method of the unreasonable pressure field was dicussed in the article. The expressions of correction equations of speed in different directions were derived. As an example, the speed field and temperature field of liquid flow at right angles were simulated. The results showed that the maximum temperature difference between both ends of the model is about 50 , and the minimum temperature difference between the both ends is about 30 at y=0.375m. The lowest temperature is at the exit of the flow field. The results were compared with the staggered grid results, which verifies the calculation method proposed in this article is reasonable.
