    "abstract": "The contribution of the \"rapid\" part of the pressure diffusion to the\nturbulent kinetic energy balance is analyzed, and a new model to describe its\neffect is suggested. A new transport equation for the turbulent kinetic energy\nis derived. The new k-equation does not require any modification in the\nstandard epsilon-equation. A new k-epsilon model, which includes the new\nk-equation and the standard epsilon-equation, is validated in four separated\nflows: a planar diffuser, over a backstep, in a channel with wavy walls, and in\nan axisymmetric combustion chamber. It is shown that a new model reproduces the\nmean velocity, shear stress, and turbulent kinetic energy profiles and the skin\nfriction coefficient in very good agreement with experimental data.",
