Two Dimensional Model

A change of surface pattern of materials during polishing is simulated and analyzed from the fractal point of view. We have proposed a simple two-dimensional model for microscopic processes of polishing. We have obtained a result that the time dependent fluctuation of surface scales with the momentum of the polishing particle.

Set Up

Averaging pitot tube has been applied in practice more often in these years. This paper set up the two-dimensional model of the bullet-shaped averaging pitot tube, numerical simulation based on CFD was used to investigate the changes of flow coefficient along with the Reynolds number. The geometric size of the section was changed to investigate how it influences the flow coefficient and differential pressure. To guarantee the accuracy of the simulation, the grid and the simulation model were investigated too.
