Simulating Lubricant Churning in a Gearbox with CONVERGE

CONVERGE’s autonomous meshing with cut-cell approach easily handles moving boundaries, as demonstrated in this simulation of a bevel gear reducer gearbox. We used volume of fluid (VOF) modeling to capture the churning of the lubricant inside the gearbox and Reynolds-Averaged Navier Stokes (RANS) modeling to simulate the turbulence. The first view shows how the lubricant splashes and spreads, coating the surfaces as the gears turn. The second view shows a slice with the mesh overlain. You can see how CONVERGE’s meshing approach seamlessly accommodates the moving gears. In addition, Adaptive Mesh Refinement (AMR) helps to efficiently resolve the lubricant-air interface, thus optimizing the total cell count while still maintaining a sharp interface. Convergent Science's CONVERGE is an innovative computational fluid dynamics (CFD) software that eliminates the grid generation bottleneck from the simulation process through autonomous meshing.
