Modeling of in-cylinder flow using overset mesh

Overset mesh has gained popularity in modeling applications with complicated geometries due to its flexibility in handling arbitrary motion. This paper presents a study on application of overset mesh for in-cylinder flow using STAR-CCM+®. Different mesh strategies were investigated including trim, poly, and direct mesh. It was found that the results are similar from different mesh while ploy mesh overall produces more robust results than trim mesh.

Pulley blade shape optimization using Optimate+

Target is to design optimized blade shape on a pulley in order to cool down a rubber that drag a belt.

The blade shape designs are optimized using Optimate+ and  STAR-CCM+® 3D CAD model.

Parameters are defined and 100 simulations are launched in order to find the best design.

Steady simulations are performed with rotation, and the best design giving high heat transfer coefficient and high velocity is found.
