Problem Description

This study investigated snowfall in the park using the DPM (Disctere phase material) method. In this simulation, two types of material are used: air and particles that snow in a Disctere phase material. Trajectories of particles within the park were observed using Ansys Fluent software.

 Geometry & Mesh

the 3-D geometry of the present model is carried out using Spaceclim software.

For grid generation, unstructured mesh with 1553972 elements in the Ansys meshing module was utilized. The curvature Method was used to focus on grid-sensitive areas. The following figure shows the mesh generation for this problem.

Snowfall CFD Simulation

We consider several assumptions to simulate the present model:

  • Flow equations don’t solve.
  • The simulation is transient.
  • The effect of gravity on the fluid flow is 9.81 m.s-2 along the y-axis downward.

Also, The table below shows the characteristics and values of boundary conditions, along with the models and hypotheses.

Finally, the particle tracking values in the park are extracted, and the snowfall animation is attached.

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
