Pressure gradient alignment with strain rate and scalar gradient in simulated Navier--Stokes turbulence
Journal Article
·
· Phys. Fluids; (United States)
In a simulated turbulent shear flow the pressure gradient caused by velocity fluctuations alone has increased probability for alignment with the most compressive strain direction, which is similar to passive scalar-gradient behavior. The pressure-gradient component depending on the mean shear indicates no correlation with the strain directions.
