Sir, thank for this video and many others. I have been following them. you explain thing with much clarity. I am wondering if you could couple it with heat transfer in liquid. the initial velocity will be set to zero and movement will be prompted by expansion of liquid oil caused by heating.
Thanks for the videos, im following them daily. I would like to hear about level set parameters more. My questions are, is it really necessary to set the solver Fully Coupled? Seggragated approach should do pretty much the same. Secondly, why didn't u assign Wetted Wall? Not sure if its needed though, this option is pretty much confusing for me.
I created another video on the wetted wall. When you do not assign anything it takes whatever was available by default. Please watch this video it may be helpful ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NjbjWxEA_NI.html
@@pioneerofsuccess4054 I have read some literature, in which they say euler -euler method is good for fluidized bed simulations. what is the difference between euler -euler method and particle tracing method, If possible can you do a video on both.
@@pioneerofsuccess4054 How do we do patching (like in Ansys) in comsol.I wanted to set initial conditions (volume fraction) in some regions of the domain initially only
@@lakshmisreep Euler-Euler model is a model where we take dispersed phase as interpenetrating continuum in the contiguous phase and RANS equations are solved for each of the phase. This is computationally less expensive and since fluidized bed are having domain size of industrial scale, hence it is preferred. On the other hand, particle tracing method is an Euler-Lagrange model where, dispersed phase is taken as collection of particles for which Newton's law of motion is solved for each particle. Continuous phase is solved through RANS approach. It is highly accurate but computationally very expensive and therefore not preferred for Industrial scale problems. For more insight, you can refer
