Hello. I'd like to simulate a blood flow under magnetic fieldand model the blood as ferrofluid. Which module should I use? I assume i can use magnetic field no currect and single phase laminar flow?
Hi, To simulate blood flow under a magnetic field, where the blood is modeled as a ferrofluid, you will need to couple fluid dynamics with magnetic field simulations. Suggested Modules: Magnetic Fields (mf): You are correct in assuming you can use the Magnetic Fields, No Currents interface if the current is not a factor in your system. This allows you to model the magnetic field acting on the ferrofluid (blood) in your simulation. Single-Phase Flow (spf): To model the flow of blood, you can use the Single-Phase Laminar Flow interface if the blood flow is slow and can be assumed to be laminar. If the flow is turbulent, you may need to switch to the Turbulent Flow module. Multiphysics Coupling: Use the Magnetic Forces multiphysics coupling to account for the interaction between the magnetic field and the ferrofluid. This will enable you to calculate the force exerted by the magnetic field on the ferrofluid (blood) and integrate that into the fluid flow equations. You may also need to define the magnetization properties of the ferrofluid based on how blood behaves under the influence of a magnetic field (e.g., defining magnetic susceptibility). Hope this will help.
@@LearnwithSAI hello. I modeled with mfnc and laminar flow module and I added kelvin force as a volume force where only kelvin force is added into momentum equation. (Lorentz force is negligible). The results look OK. Thanks!
please how can we calculate the number of bejan with comsol and if we can make an example of geometry like this article 'Natural convection and entropy generation of hybrid nanofluid in double annulus separated by a thin rotating partition under magnetic field'
Thank you for your question! The current model in the video assumes a fluid with constant viscosity. However, if you want to simulate fluids with different viscosities, you can modify the material properties to reflect this by setting up separate domains or using a viscosity function to vary the viscosity based on certain conditions (like concentration or temperature).
Thank you for your question! To compute particle temperature in COMSOL, you need to couple the Particle Tracing module with a Heat Transfer module. Here’s a general approach: Activate the Heat Transfer in Fluids: Add the Heat Transfer in Fluids module to your model to account for temperature distribution in the fluid. Enable Particle Temperature: In the Particle Tracing for Fluid Flow module, go to the Physics tab, and select Heat Transfer to Particles. This will allow you to track the temperature of the particles as they move through the flow. Set Initial and Boundary Conditions: Define the initial temperature of the particles and apply appropriate boundary conditions for heat transfer between the fluid and particles. Run the Simulation: After setting up the above, run the simulation to compute the temperature distribution of both the particles and the fluid. Let me know if you need more detailed guidance on setting this up!
Hi can you please upload a video on how to mix 2 different gases with different concentration to get a diluted gas at the outlet using comsol
Thanks for the suggestion! I’ll work on it and, once the model is ready, I'll create a video on it.

Very well explained. Please keeping making videos!
Thanks, will do!

Please make a video on how to simulate 2D electroosmotic flow with two reservoir connected with a conical channel.
Sure, will simulate soon.

A bit complex two-way coupled numerical modelling, possible to simulate in comsol.
Pls is this for different viscosity!
