RANS 湍流通道流附matlab代码.zip

## RANS simulation of a turbulent flow through a channel [](https://es.mathworks.com/matlabcentral/fileexchange/101098-rans-turbulent-channel-flow)   An incompressible fully developed turbulent flow is considered in a channel (statistically stationary and homogeneous in directions parallel to the wall). The numerical code compares different characteristic properties of a turbulent flow, e.g., mean velocity profiles $U/u_\tau$, turbulent kinetic energy $k/u_\tau^2$, dissipation $\epsilon/(u_\tau^3/h)$, turbulent viscosity profiles $\nu_T/(u_\tau h)$, for various turbulent Reynolds numbers Re $_\tau$ = \{180, 550, 950, 2000\} using different turbulence models: * Length mixing, * TKE, * k-epsilon. I have included the report (written in spanish) that I wrote along the numerical code. ## Numerical models implemented: Models | Transport eqs. | ------------- | --------------- | Length mixing | 0 | TKE | 1 | k-epsilon | 2 | ## Database Data extracted from direct numerical simulations of a fully developed plane turbulent channel flow.
