A closed-form analytical model for predicting 3D boundary layer displacement thickness for the validation of viscous flow solvers

AIP Advances, 2018
A closed-form analytical model is developed for estimating the 3D boundary-layer-displacement thickness of an internal flow system at the Sanal flow choking condition for adiabatic flows obeying the physics of compressible viscous fluids.

Measurement of entropy production rate in compressible turbulence

, 2006
The rate of change of entropy $\dot S$ is measured for a system of particles floating on the surface of a fluid maintained in a turbulent steady state. The resulting coagulation of the floaters allows one to relate $\dot S$ to the velocity divergence and

Splitting of inviscid fluxes for real gases [PDF]

Flux-vector and flux-difference splittings for the inviscid terms of the compressible flow equations are derived under the assumption of a general equation of state for a real gas in equilibrium.

Influence of turbulent mixing on critical behavior of directed percolation process : effect of compressibility

, 2017
Universal behavior is a typical emergent feature of critical systems. A paramount model of the non-equilibrium critical behavior is the directed bond percolation process that exhibits an active- to-absorbing state phase transition in the vicinity of a ...
