Get Price### Using CFD to Understand the Effects of Seam

CFD studies have been conducted on a smooth sphere and four different soccer balls, including a 1/3 scale model soccer ball and a real ball. The results have been compared to previous wind tunnel results of these balls, and the drag coefficients show consistent trends. It was found that the seam width and sharpness have a large effect on the ball's aerodynamic behaviour. Various other balls

01.01.2015· The pure CFD model fails to predict the free surface profile of the slurry air system inside the mill but the coupled model can effectively predict the free surface, so we infer that there is a major effect of drag forces of particle on the fluid. Once the drag force from the DEM simulation is incorporated as momentum source terms in the fluid cells the slurry profile from the coupled model gives a better

CFD stands for computational fluid dynamics (and heat transfer). As per this technique, the governing differential equations of a flow system or thermal system are known in the form of Navier–Stokes equations, thermal energy equation and species equation with an appropriate equation of state. In the past few years, CFD has been playing an increasingly important role in building design
