Turbulence models in CFD
CFD stands for computational fluid dynamics. A vast field of numerical analysis in the field of fluid s flow phenomena is represented by this topic. Primarily CFD deals with understanding and solving ordinary and partial differential equations and much more than that. turbulence when present in a flow dominates all other flow phenomena.The modeling of turbulence thus greatly improves the quality of numerical simulations.
The main steps in solving a CFD problem is
- geometry and grid generation
-setting-up a ....etc

Introduction
CFD
CFD is computational technology that enables us to study the dynamics of things that flow.
Using CFD, a computational model that represents a system or device that we want to study is built. Then we apply the fluid flow physics to this virtual prototype, and the software outputs a prediction of the fluid dynamics.

Application
fluid flow, heat transfer , mass , phase change , chemical reaction, mecha ....etc

The preceding chapter described the basic steps and concepts involved in FLOTRAN analyses. This chapter describes a sample laminar and turbulent fluid flow problem. Chapter 5, FLOTRAN Thermal Analyses, offers additional examples based on a buoyancy-driven flow problem.Before you begin reading about the laminar/turbulent example, note the following:

The example problem described is only one of many possible FLOTRAN analyses.

It does not illustrate every technique you might use in a FLOTRAN analysis, and is in ....etc

Computational Fluid Dynamics (CFD) is an extremely effective tool to solve problems involving mass and even heat transfer. Problems with varying degrees of complexities can now be easily solved with the help of appropriately written CFD codes. A CFD analysis is performed to:1)understand the nature of fluid flow around differsnt geometries like an aerofoil or any other shape for that matter.2)find the lift and drag effects for an aerodynamic structure.3)analyse the heat transfer by fluids in devices ranging from radiators to furnaces to gas turb ....etc

I am a mech student taking a CFD course, I've been trying to implement the SIMPLE algorithm for 2D collocated grid to solve for velocity fields and pressure fields using matlab. I'm having lots of trouble writing the code since I'm new to programming. If you could provide me with a code on matlab I could understand from to finish building my own code.
thanks ....etc
