The Particle Tracing Module, an add-on to COMSOL Multiphysics, can be used to enhance fluid flow simulations and extract more valuable simulation results. The module enables you to track particles and work in conjunction with CFD simulations. Get an overview of the module in this video:
ANSYS Explicit Dynamics Simulation: Steel vs. Lead Collision Witness a fascinating simulation of two spheres, one made of steel and the other of lead, colliding at high velocity! This study demonstrates the capabilities of ANSYS Explicit Dynamics in capturing real-world material behavior during impact.
In a previous post, I showed the beveled supersonic nozzle. If you want to use it in a Laser Wakefield Acceleration experiment, remember that if the bevel position is chosen properly, the beveled nozzle can generate an interesting gas density profile with a flat top profile and long gas density ramp. This profile might be suitable if we want to match the electron beam emittance from one stage to the next stage or accelerator element. I did a fast CFD simulation to check it. Here are the results.
Large Eddy Simulation (LES) has recently gained importance in computational fluid dynamics (CFD). This surge is primarily due to the inherent trade-offs involved in traditional Reynolds-averaged Navier Stokes (RANS)-based CFD, such as limited design spaces, long run times, and reduced physics. In this blog post, we will focus on how users can benefit from an LES workflow using Fidelity Pointwise and Fidelity LES Solver, formerly CharLES, specialized meshing tool, and GPU-enabled wall-modeled LES code, respectively.

DAY 2 🚀 Mastering the Finite Volume Method (FVM) After exploring the basics of CFD in Day 1, it's time to delve deeper into the Finite Volume Method—a fundamental numerical approach for solving CFD problems. 💡 I came across this excellent YouTube resource that simplifies FVM concepts, making it easier to understand and apply. If you’re looking to strengthen your grasp of FVM, I recommend checking it out: https://lnkd.in/gmRYMpmt #simulation #CFD #Aerospace #Aviation #maths #FVM #engineering #innovation #technology #FluidDynamics
With our recent CFD-DEM development, we are now able to simulate the movement and interaction of non-spherical particles. Combined with our previous effort in particle tribocharging modelling, we can now explore how the particle shape affect the tribocharging phenomenon.
