How does the Reynolds Number affect my CFD model?
The Reynolds number (Re) is the single most important non-dimensional number in fluid dynamics and is recommended to be calculated before you begin any new CFD modelling project. The Reynolds Number is defined as the dimensionless ratio of the inertial forces to viscous forces and quantifies their relevance for the prescribed flow condition: Where U∞...

Tips & Tricks: Turbulence Part 2 - Wall Functions and Y+ requirements
Learn from the Expert: Turbulence Training with Dr. Florian Menter
Dr. Menter is a world-recognised expert in turbulence modelling.
He developed the widely used Shear-Stress Transport (SST) turbulence model, which has set a milestone in the accurate prediction of aerodynamic flows. He has also contributed to the formulation of one-equation turbulence models, advanced near wall treatment of turbulence equations, transition modelling and unsteady flow models. He has been in charge of the turbulence modelling program at ANSYS for more than 15 years and has been involved in a wide range of industrial modelling challenges.
Tips & Tricks: Turbulence Part 1 - Introduction to Turbulence Modelling
We will now focus on Turbulence Modelling, which is a critical area for any engineer involved with industrial CFD. There are a number of different approaches so it is important that you have solid grounding in this area to enable you to choose the appropriate model for your simulation requirements. It is worth noting that in August...
Tips & Tricks: Convergence and Mesh Independence Study
The previous posts have discussed the meshing requirements that we need to pay attention to for a valid result. It is important to remember that your solution is the numerical solution to the problem that you posed by defining your mesh and boundary conditions. The more accurate your mesh and boundary conditions, the more accurate...
Tips & Tricks: Global Meshing Controls in ANSYS
Welcome to the first in LEAP's series of CFD Tips & Tricks blogs. The topics for this first series of blog entries will focus on the selection of efficient and appropriate meshing methods, mesh sizing and mesh controls in ANSYS Workbench Meshing. Meshing is one of the most important influences on CFD simulation accuracy, although it...
How the top Formula One (F1) teams stay on the podium
You may already know that Computational Fluid Dynamics (CFD) is currently used by all Formula One teams as part of their ongoing development for their aerodynamics and cooling packages. Since the technologies pioneered in F1 car development regularly flow through into other engineering industries, we felt that a post on this topic was the perfect...
