## RANS simulation of a turbulent flow through a channel

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 <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static">$U/u_\tau$</math-renderer>, turbulent kinetic energy <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static">$k/u_\tau^2$</math-renderer>, dissipation <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static">$\epsilon/(u_\tau^3/h)$</math-renderer>, turbulent viscosity profiles <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static">$\nu_T/(u_\tau h)$</math-renderer>, for various turbulent Reynolds numbers Re <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static">$_\tau$</math-renderer> = {180, 550, 950, 2000} using different turbulence models:

• Length mixing,
• TKE,
• k-epsilon.

Additionaly, I have included the report that I wrote (in spanish) along the numerical code.

## Numerical models implemented:

Models Transport eqs.
Length mixing 0
TKE 1
k-epsilon 2

## Database
