As the CFD engineer, you need to describe boundary conditions for your turbulence equations. This article typical turbulence values for normal simulations.
Turbulence does tricky things near walls. Turbulence is most critical near the wall, so how to consider near wall effects? Learn more here.
Turbulence is the defining feature of modern computational fluid dynamics (CFD). What type of approximation, and which turbulence model should you select?
How do we stretch the limits of linear algebra to accommodate non-linear CFD equations? How do we take the mathematics from one cell and apply them to millions of cells?
CFD convergence is not an exact science. Monitors, flow patterns, and residuals. Learn how to use these tools and reliably juge convergence.
If we want to solve the equations of computational fluid dynamics (CFD), we need a way to fake calculus. Enter interpolation equations.
Transport equations form the fundamental language of CFD. Today we explain transport equations and the significance of their terms.
Navier Stokes is essential to CFD. Today we review Navier Stokes Equation with a focus on the meaning behind the math.
Just fresh out of college, and the boss assigned your first project for computational fluid dynamics (CFD). You are excited. You can’t wait to begin the challenge. You sit down at your computer, start up the CFD software . . . and freeze like a deer in headlights. How to begin? What to do first? Today we discuss the general workflow for a CFD project and highlight some general modeling advice.
What happens behind the curtain when the CFD engineer goes to work? What goes into making a CFD simulation? As a project manager, you need to understand the workflow of a CFD project; this helps you plan the project and track budget expenses. When we understand the workflow, we know the right questions and can anticipate project delays.
Is there anything that CFD can’t do? Practically speaking, we can achieve the result, but you may regret paying for the answer. Several CFD projects involve combinations of different CFD methodologies. Combined together, they evolve into a major project risk. Gain some insight about the risk factors for your next CFD project. Plan a strategy to minimize project risks so that you don’t get caught by combining unknown cost increases.
What is CFD? It uses the computer and adds to our capabilities for fluid mechanics analysis. If used improperly, it can become an incredible waste of time and money. With the right engineer, CFD can be cost effective, incredibly informative, and offer unparalleled flexibility. But what is this wonder of modern science? Learn more about this expansive tool.
