| Description | Journal: Iop Conference Series: Earth and Environmental Science In this paper, a three-dimensional hydrodynamic model based on adaptive mesh was established. The cubic mesh based on octree structure was adopted to solve the three-dimensional Navier-Stokes equation by the step-by-step pressure decomposition method, which realized the automatically encryption and coarsening of the grid. The calculation of three-dimensional square cavity flow showed that the calculation results of this model are in perfect agreement with those of Chen, and the calculation accuracy is high. Through the calculation of three-dimensional flow around a cylinder, the model can automatically encrypt the grid near the complex boundary, and can refine and coarsen the grid reasonably through the vorticity field. Meanwhile, it can also reduce the calculation amount and improve the calculation speed while maintaining the calculation accuracy. |
