CFD (Computational Fluid Dynamics)

For Hydraulic Optimization

CD Adapco’s commercially available STAR CD and STAR CC+ software tools are employed by Varel to perform CFD analysis on new bit designs. The 3D model developed in Pro-E is loaded into the CFD model. The Varel analyst works through a proprietary set of process steps to prepare the model for analysis.

The output from the CFD analysis is used to identify areas of high erosion potential, reverse flow, or hydraulic stagnation. When the output reveals the potential for hydraulic deficiencies in the bit body design the model is ported back to Pro-E to make recommended adjustments to nozzle locations and orientations. It is then remodeled in STAR. Once the hydraulic model is determined to be optimized the Pro-E CAD design is ported into the Pro-E CAM model.
