Numerical Investigation of Subsonic Flow through an Aggressive Flat Bottom Diffuser [PDF]
Airflow through an aggressive, constant pressure gradient, flat-bottomed 2D diffuser is simulated with the compressible version of the stabilized, implicit finite element code PHASTA. The freestream Mach number of fluid entering the diffuser is held at a

An analysis of a swimmer’s passive wave resistance using experimental data and CFD simulations
The passive resistance of a swimmer on the free surface has previously been researched experimentally. The contribution of wave resistance to total drag for a swimmer with a velocity around 2.0 m.s-1 was found to vary from 5% for Vorontsov and Rumyantsev
