Computation of viscous compressible turbulent aerodynamic flows

A general proof-of-concept prototype multiblock system, which provides Euler and Navier-Stokes flow solution capability for complex configurations, has been developed. The flow system is formulated on a multiblock concept which divides the flow field into non-overlapping blocks, arranged so that bod...
