drag and lift coefficients for CFD and fluid dynamics

Drag coefficients in fluid dynamics

This week at the Volupe blog we are announcing our new web page regarding drag coefficients. The web page is an addition to the “Volupe Engineering Handbook” that already comprises the y+ calculator and the information on dimensionless numbers. The aim is to provide useful information on our webpage, that can help the calculation engineer …

Analyzing particles on a stick boundary using boundary sampling in Simcenter STAR-CCM+

In this week’s blog post we will investigate Lagrangian post-processing and more specifically the function of boundary sampling. We will use it to track particles hitting a wall with a stick boundary condition and give an example of how to analyze data on these particles. Setting up the boundary sampling Boundary sampling is a way …

Streamlines in Simcenter STAR-CCM+

Visualization of results is always important. We will therefore look closer one of the more popular visualization tools, streamlines, in this week’s Volupe blog post.  What are streamlines?  Streamlines are flow paths for massless particles calculated based on the flow field. Streamlines can provide an understanding of how the fluid will flow in the domain …

Turbulence for multiphase simulations in Simcenter STAR-CCM+

Last week’s blog post was about transition modelling in Simcenter STAR-CCM+. I was thinking that this week we keep working with turbulence in Simcenter STAR-CCM+. Specifically, I will discuss multiphase turbulence and how that is treated, and even more specifically, how to simulate turbulence in your Eulerian multiphase simulation (EMP). Back in version 2021.1, mixture turbulence …
