Pointwise awards Meshy for propeller mesh testing cavitation.
The winning mesh by Prof. Rickard Bensow from Chalmers University of Technology.
Pointwise recently named Prof. Richard Bensow from Chalmers University of Technology the winner of its Meshy Award. The winning mesh is used to simulate the cavitation on a ship propeller by assessing the effect of the installation upstream, energy efficiency and stator blades on the propeller inflow.
“Prof. Bensow’s entry, selected from a number of other qualified offerings, demonstrates a mastery of both Pointwise and CFD (computational fluid dynamics) in general,” said Dr. John Steinbrenner, VP of R&D at Pointwise.
The winning mesh was announced at the 2014 Pointwise User Group Meeting. Meeting attendees obtained t-shirts depicting the winning mesh. The award was offered to the creator of the most outstanding mesh created using Pointwise software. The meshes were judged on their originality, visual appeal and uniqueness.
Steinbrenner said, “Prof. Bensow has produced a visually and analytically impressive multi-scale representation of a tanker ship stator-propeller blade geometry … He employs a combination of surface mesh types, including structured quad surface meshes arranged in C-H topologies wrapping the rotor and hub, high aspect ratio anisotropic triangle elements on the stator blades, and isotropic Delaunay and advancing front triangles on the remainder of the surfaces. These surfaces used in conjunction with the T-Rex mesher result in a 20 million element volume grid of mixed type (tet, pyramid, prism and hex) that forms a precise and accurate flowfield framework for his LES flow solution.”
Given Professor Bensow’s expertise in the field, it isn’t surprising that he was able to produce a mesh of such complexity. Currently, Prof. Bensow is the Head of Research in Hydrodynamics at the Department of Shipping and Marine Technology at Chalmers University of Technology in Gothenburg, Sweden. Additionally, he is the director of the Rolls-Royce University of Technology Center in Computational Hydrodynamics. Finally, his research specialty includes the study of computation methods in transient flow phenomena, such as noise and cavitation, around marine propellers.
