Featured Fluid Dynamics Case Studies
CFD Thermal Analysis of Driver Thermal Comfort in Tractor
- Segregate the necessary and unnecessary parts from the import model and make it ready for surface wrapper operation. The reason to go for wrapper in this CFD Modeling is that this model had too many problems like free edges, pierced faces, and non-manifolds.
- Create a domain around the tractor model so that during wrapper operation full domain with a tractor can be extracted for the CFD Analysis using the seed point method.
- Create a surface wrapper operation, tick gap closure option and set appropriate size settings. The wrapper was performed in three stages coarse, medium and fine. The reason to do this is to make sure that necessary features are captured with a limited number of faces. Note: At this point HX, Fan must not be included.
- Create a subtract operation to subtract HX, a fan from wrapper.
- Assign parts to region and set appropriate BC’s inside the CFD Flow Simulation Model. A single stream HX method is used here.
- Create mesh operation for HX, fan, and wrapper with the domain. Trimmer mesh so per part meshing.
- Set physics segregated flow with the K-omega turbo model.
HVAC CFD Analysis of Car Cabin Temperature Distribution
- Segregate the necessary and unnecessary parts from the import model and make it ready for surface wrapper operation. The reason to go for wrapper when performing pre-processing for the CFD Simulation is that this model had too many problems like free edges, pierced faces, and non-manifolds.
- Create separate surfaces for passenger’s faces so that it can be used later to create reports.
- Create a surface wrapper operation and extract the internal volume of the cabin using the seed point method. So that it extracts all the traced path during the Computational Fluid Dynamics Simulation Process.
- Assign parts to regions and set appropriate BC’s and set physics (Segregated flow, K-omega model)
- Create Automated mesh operation and provide necessary settings for the Fluid Flow Simulation.
- Create reports and plots
