Turbulent pressure (or turbulence pressure) is a component of pressure, e.g., of a gas, due to turbulence. The presence of turbulence implies some deviation from hydrostatic equilibrium, and models of pressure incorporating a component based on turbulence can be significantly better in some situations. Different models are used to determine such a pressure component. When magnetism is significant, magnetohydrodynamics may be useful. They are used in models of stars, for example, when modeling asteroseismology, when modeling supernovae, and modeling gas clouds, up to the size of intracluster media.
