This repository is dedicated to the individual research project during the masters program International Master's in Turbulence (IMP-Turbulence) at École Centrale de Lille, France 2017-2019.

The repository contains the work done on computation of Couette-Poiseuille flow with a mixing-length model of turbulence. This work was done as of part of turbulence practices - Individual Research Project at École centrale de Lille, France as a part of Masters program in Turbulence. The project was a supervised of Dr. Jean-Philippe LAVAL.

Objective: To write a simple program for a turbulent model for a simplified case and compare the results with the theoritical solutions in the laminar case and with the experimental results in turbulent case. Several parameters such as grid stretching, number of grid points near the walls are investegated.

Couette flow can be described as the flow of a viscous fluid between two parallel surfaces one of which is moving tangentially relative to the other. The flow is driven by virtue of viscous drag force acting on the fluid, but may additionally be motivated by an applied pressure gradient in the flow direction which is then a case combined with the Poiseuille flow. Shear-driven fluid motion is one of the most common example of couette flow.
