The dimensionless kinetic energy dissipation rate C(epsilon) is estimated from numerical simulations of statistically stationary isotropic box turbulence that is slightly compressible. The Taylorâ€¦ (More)

We consider gas flow in pipe networks governed by the isothermal Euler equations. A set of coupling conditions are required to completely specify the Riemann problem at the junction. The momentumâ€¦ (More)

Nonhelical hydromagnetic turbulence without an imposed magnetic field is considered in the case where the magnetic Prandtl number is unity. The magnetic field is entirely due to dynamo action. Theâ€¦ (More)

Direct numerical simulations and mean-field theory are used to model reactive front propagation in a turbulent medium. In the mean-field approach, memory effects of turbulent diffusion are taken intoâ€¦ (More)

The effect of compressibility on the onset of non-helical turbulent dynamo action is investigated using both direct simulations as well as simulations with shock-capturing viscosities, keeping,â€¦ (More)
