Balancing Meshing Time with Solution Accuracy
Posted Tue April 09, 2019 @10:56AM
 Print version Email story Tweet story
Application In 1963, Craig Breedlove set the world land-speed record in the Spirit of America, a record that he would later reclaim several more times in the next two years. Fifty years later, Breedlove has decided that it is time to bring the title back to America. In a new team led by Breedlove, the Spirit of America is being revived with the goal of once again claiming a new world record for land-speed vehicles.

Historically, land-speed vehicles were shaped by rule of thumb aerodynamics. However in the 50 years since the first turbojet vehicle officially set a land-speed record, computational fluid dynamics (CFD) has matured to a point where it can be inexpensively used to help simulate performance characteristics on such vehicles.

Application Large cargo ships routinely have Underwater Radiated Noise (URN) signatures from their propellers of 150dB+, louder than jet engine take-off noise. Oscar Marine has developed a new propeller design which reduces URN by between to 17dB and 21dB (an over 100 times reduction in noise power) in the frequency range most damaging to marine fauna.

 Print version Email story Tweet story
Application The development of the Rimac C_Two all-electric hypercar presents unique aerodynamic design opportunities and challenges due to the absence of an IC engine.

The internal aerodynamics team started the development based on early design concepts, developing from a closed body in 2D, moving to the 3D analysis, using CFD (Computational Fluid Dynamic) simulations and refining the status constantly.

 Print version Email story Tweet story
Application Details of novel computational models of the human lung have been presented at the 10th International Aerosol Conference.

The personalized models, based on advanced mathematical modeling of the human body and lung geometry, can be used to predict how aerosols will be inhaled, deposited on airway walls, and absorbed and cleared by lung physiology.

Design Optimization of a Diffuser Pump Stage by 4 points in Efficiency
Posted Tue September 25, 2018 @09:26AM
 Print version Email story Tweet story
Application In this project, the client asked ADT to perform a hydrodynamic design optimization of a strongly interacting diffuser pump stage using the inverse design code TURBOdesign1.

The focus of the design was to minimize the hydrodynamic loss generation, particularly in the diffuser channels.
