Hi,
I want to create a model to see how the light(laser) is absorbed in a tube fill with water (absorption vs length of the tube)using COMSOL. I already created geometrical structure of the tube, but confused about the physics and boundary conditions.
So, which physics should I use and which boundary conditions will I use? Is there any model example that I can follow?
For reference, I am attaching two figures.
*Capture 11 ( I want to recreate this model and plot the absorption vs length of tube)
[Capture 11 is taken from Article Fast-pulsing LED-enhanced NMR: A convenient and inexpensive ...
)*Capture 12 ( my design in COMSOL)
Thanks for Helping.
Are you trying to model radiative transfer equation? i am not sure if it is possible via Comsol.
Not sure about the radiative transfer equation. But want to model a tube in which light will absorb, and want to plot absorption vs length of the tube.
tube is my absorbing media.
Analyzing capillary action in CFD necessitates the integration of multiphase flow models to accurately depict the interactions between distinct phases, such as a liquid and a gas, which are essential for capturing the dynamics of capillarity. Crucial to this simulation is the modeling of surface tension, a key force driving the fluid within narrow spaces, requiring CFD software to precisely account for surface tension forces at the interface of different fluids or between a fluid and a solid. Equally important is the implementation of the contact angle, the angle at which a liquid/vapor interface meets a solid surface, which plays a pivotal role in determining the hydrophilic or hydrophobic nature of the material and thus impacts the capillary action.
Hope this helps
