COMSOL Simulation of MEMS Heat Exchangers
Переглядів 2732 місяці тому
In this video, we demonstrate how to build and solve a heat transfer problem involving both conduction and convection using the Nonisothermal Flow multiphysics coupling in COMSOL Multiphysics. The example focuses on a stainless-steel MEMS heat exchanger, commonly found in lab-on-a-chip devices used in biotechnology and microreactors like those in micro fuel cells. We'll explore the heat exchang...

COMSOL Simulation: Velocity profile of liquid confined between a moving and stationary wall: Part 2
Переглядів 2155 місяців тому
In this video, we examine the transient viscous diffusion of momentum, exploring how the velocity changes over time between a stationary lower plate and a moving upper plate in a confined space in COMSOL Multiphysics. We consider two cases: 1. Upper wall is moving with a constant velocity such as vx=vx0 (Part 1). 2. Upper wall is oscillating to the right and left in such a way that its x veloci...

ASPEN HYSYS Simualtion of Catlytic Reaction in a Plug Flow Reactor
Переглядів 4919 місяців тому
Here we simulate the production of styreren in a catalytic Plug flow reactor. Styrene is produced by catalytic dehydrogenation of ethylbenzene at temperatures starting from 630◦C and pressures slightly above atmospheric pressure in the presence of water steam. Two main side reactions take place in this process: pyrolysis of ethylbenzene to benzene and ethylene and ethyl-benzene hydrodealkylatio...

Hello, can you help me of simulation
hi, sure, let me know what you want to simulate
Great work sir. Keep it up
Informative video sir.. Kindly sir make a video on how to download the comsol and aspen..
Hello. I have a 2D system. There is a vein with blood flow and I want to define biological tissue. For 2D system, I assign non-isothermal laminar flow for flow domain and heat transfer in fluids for biological tissue. Is it correct? Should I assign heat transfer in solids to define the tissue? thanks
Hello. Can you instruct how to simulate a laser pulse acting on skin tissue! Thank you!!!
Excellent video, sir. Kindly bring some videos on 2D axisymmetric simulation of nucleate boiling using phase field method
Thanks for appreciation and suggestions. I shall try to upload videos on boiling soon.

Can you please demonstrate Transient Elastohydrodynamic squeeze film interaction in comsol
Can you send me this presentation!!!
Hello, there is no ppt. It is a step by step tutorial. You may find this example in the book referred in description.
Thanks for the video, it was instructive. When would you release the part2?

Hi, can u help me to calculate a heat transfer coefficient for my thesis because i still confuse about this software? I already have the result after run the simulation
Hi.. sure..please share the problem
@@chemsim3160 Okay Sir, i will send the problem through your email. Thank you
@@chemsim3160 I need help too 🥺🥺
Can you please help me in calculating avg nusselt no. In a 3d rectangular channel which is same as the one u have used just its rectangular? In which fluid is moving in turbulence and a constant flux is at base

Thank you for this informative video, I would like to ask, Is it possible to model a Transient HT problem for a an Insulated tank that contains aggregate held in 100 c and see the temperature of the aggregate after 24 hours, in other words what would be the temperature of the aggregate after 24 hours if it was preheated and sent to the tank at 100 C. I appreciate highly if you could suggest something or tip sth in this regards. which boundary conditions may be used in such case, and how to model the aggregate? Thank you in Advance
could you perform optimization for this case please
Hi, you calculated heat transfer coefficient for boundary 4 which is not a wall of flow or fluid?
Boundary 1 is symmetryy, boundary 2 and 3 are inlet and outlet, respectively, while boundary 4 is wall, which is exposed to heat flux qw.
thnks for this vidio what this name method?
any vedio for newly heat exchanger which we have to design

thank you for this video but i,m working on absorption cycles water/libr via aspen plus and i'm blocked on the fiste step becouse i dont have the flow rate of the water between condensor and evaporateur an i,m worked on low pression so please if you could help me how i can figure out this problem I will be grateful and thank you
sir, I thinked you should record your voice over with it. And my suggestion is that make a basic course of comsol, that how we will known that which model we need to use, which equation will be using etc.
V good dear keep it up
Voice over needed😊
So, what the result value number
Check at 10:46
May I get your contact email
Wow
Thanks bro greetings from Poland
How to model solid material, but surface of the material will be changing with time based on environment temperature. For different materials the response will be different. For example during when the whether is 5 degC, some materials like glass with time can reach 2 degC meanwhile at same condition other materials like plastic will be between 4-5degC. Thanks
So, basically you're saying that the surface or basically the material is non-homogenuous???? Then, you must model the material during the construction of Geometry carefully.
Hello please i have a question could share your email?
Hello nice demonstration using very common question. Can you please tell me why you did "Union" operation. Is that mandatory? What if we don't do that, please explain!
Thanks 🙏
Great video! Thank you!
hello, I have a problem on comsol, I have not found a solution to make a twist by fixing the Z axis
can you elaborate? I did not get your question. Where in this simulation you actually want to fix the z-axis?
Where did you get the th out?
Line 12 calculates the value of Th_out
