There is a concern in the computational fluid dynamics community that mesh generation is a significant bottleneck in the CFD workflow. This is one of several papers that will help set the stage for a moderated panel discussion addressing this issue.

Hypersonic boundary layer transition impacts vehicles through increased heat transfer and drag, alters a vehicle’s flight path, and is of great concern for hypersonic vehicles. However, it is difficult to predict real world full scale performance w

A computer model of a blow-down free-jet hypersonic propulsion test facility exists to validate facility control systems as well as predict problems with facility operation. One weakness in this computer model is the modeling of an air ejector diffus
