Coding turbulent diffusion coefficient for a scalar equation
Let’s start by dissecting the title, since it’s quite a mouthful one! First thing first, I am dealing with a turbulent flow then I am solving a scalar equation and I got to code something, so UDF stuff! It might sound a bit daunting, but it is rather a simple problem, yet the typical written resources are all over the place. I decided to gather bits and pieces from here and there and put everything into a step-by-step and easy-to-follow blog post.
