Application By Nick Wyman
Director, Applied Research
Pointwise, Inc.

Effective use of overset grid technology can improve your simulation results. New features coming in the next release of Pointwise, will ease the burden of constructing an assembled overset grid system.

Overset gridding refers to the use of multiple disconnected grids to discretize the flow domain. The component grids, which can be any size, type, or shape, need only overlap each other to completely cover the solution domain.

Application By Scott Burch, CFD engineer, and Dean Cowling, Team manager
Garry Rogers Motorsport

In June 2013 Volvo Car Australia announced that Garry Rogers Motorsport (GRM) would become the base of its factory backed V8 Supercar team, joining forces with its global racing partner Polestar. Featuring a 650 horse power 5 liter V8 developed and built at Volvo Polestar headquarters in Gothenburg, Sweden, the bodywork and aerodynamics of the S60 derived racecar was to be entirely designed and constructed at the GRM headquarters in Australia. The finished product races from 0-100 kph in 3.2 sec and reaches a top speed of over 300 kph.

Application By Prof. Rickard E. Bensow
Department of Shipping and Marine Technology
Chalmers University of Technology
Gothenburg, Sweden

Unsteady propeller blade loads are important to consider in the design of the propulsion system in order to avoid problems with noise and vibrations. This is normally done through an analysis of the average wake field flowing into the propulsor in order to correctly match the different components of the propulsion system. As computational resources increase, it starts to become possible to better study the impact on the natural wake flow unsteadiness and how this influences the behavior of the propeller.

Application By Dr. V. Babu, Professor,
Department of Mechanical Engineering,
Indian Institute of Technology Madras, Chennai, India

Conventional jet engines use a turbine-driven compressor to compress air prior to combustion of fuel. The exhaust from the combustion drives the turbine and creates thrust from the nozzle to propel the plane. Ramjet engines replace the compressor with a specially shaped duct, open at the front, that uses the forward motion of the aircraft to compress air. No moving parts are required in a ramjet.
