Fluid Dynamics Investigation of the Sonic Boom on a Supersonic Aircraft Concept
Posted Mon August 03, 2020 @10:01AM
Print version Email story Tweet story
Application The return to supersonic flight is amongst the hottest topics in aviation today, as several companies (Boom Supersonic and Aerion Supersonic, among others) are actively developing new supersonic commercial airliners targeted to enter in service in the coming years. In this context, a quiet flight over land is one of the major challenges to ensure the regulatory compliance of such airliners. Several research centers and companies are building demonstrators to show large sonic boom reductions with smarter designs of all the parts of the aircraft.

What Makes Calculation of Full Port Ball Valve Flow Coefficient Challenging?
Posted Tue July 07, 2020 @12:13PM
Print version Email story Tweet story
Application Often valve manufacturers face the challenge that their valve's flow coefficient, Cv, is less than those of competing manufacturers.

Many resources are spent on valve design only to end up with an under performing valve during experimental testing.

Accurately Model Propeller Performance Using TCFD and Pointwise
Posted Mon June 08, 2020 @04:26PM
Print version Email story Tweet story
Application Pointwise has released the case study, Accurate Performance Predictions for Marine Propellers, providing benchmark validation for accurate performance of CFD simulation results.

The high demand for improving the accuracy, quality, and credibility of the CFD simulation results, should be assessed by providing a qualitative and intensive comparison with experimental measurement data.
