Know Your Mesh – Basic Methodologies

Consider the simulation of flow field past a solid obstruction. Generating a grid to solve a discretization scheme shall proceed in one of few routes. First a surface grid covering the boundaries of the solid body may be generated. In subsequent step, If a finite-difference scheme is employed, then a curvilinear coordinate system aligned with the grid lines shall be …

All About Turbulence Modeling – The “All You Can Eat” Menu

I love turbulence. Knowing how to model it in just the right fidelity is an art imho. An art I fell in love with 💕 The intention of this set of posts is to embark on a journey of connecting the dots between CFD and turbulence modeling with the phenomenological and practical concepts of engineering …

Turbulence Modeling Best Practice Guidelines: Standard EVMs – PART II

In Part I of "Turbulence Modeling Best Practice Guidelines: Standard EVMs" I have presented some motivation, and two of what I find as the most immediate and more pressing issues regarding turbulence modeling in general, namely, that before following and choosing any particular best practice guideline one should at least know the basics about each …

Turbulence Modeling Best Practice Guidelines: Standard EVMs – PART I

In the following set of posts I shall present what I find as the most effective best practice guidelines to the challenge of modeling turbulence. I shall try to keep the posts as practical as I can from an engineering standpoint, and as pointed as I can towards the best practice guidelines themselves. To be …

Some Fundamental Thoughts About Turbulence Modeling…

As far as we know, there is only one objective physical reality, but there are many ways of describing it. Usually, we refer to these ways as “theories” or sometimes "models". Ever since the days of Aristotle and his contemporaries, science has discovered many such theories or models, some may be harder to perceive but …
