COMSOL TUTORIAL 6 3D PIPE FLOW

[@julianmoreno5542]

Thank you very much, your videos are really helpful. I was wondering if is it possible to consider a gas flow and its corrosion effects in this system, and if so could you please recommend me some documents/papers that give any help?

[@abhigithnair3101]

Sir, can we perform vapor to water condesnsation process in COMSOL.

[@amiraelayeb9237]

So brilliant Mr , can i found more tutorials about flow simulation with comsol because im beginner ! Thx !

[@simranbansal5081]

Sir can you tell how to calculate pressure drop or friction factor in comsol as I have to do my final year project which is Non Newtonian fluid flow in helical coil.

[@nasrintaghavi6877]

Hi, Thank you for this useful video. Do you know how can I simulate a burst on the pipe surface, to see how the water flow through it?

[@eduAutomacao]

Very Good Video... I'm designing a WindTunnel and I'd like to know if are there anyway to simulate a screen in inlet ? I'd like to comparete the results with a turbulent test section.

[@akshaysoni1819]

Sir, I am trying to model solidification during turbulent flow for that I need to add an additional sink term in the k-epsilon turbulent flow equations. The volume force term which I am adding is for the momentum equation. could you please suggest to me how to add an additional sink term in turbulent equations? By the way, I am your junior at IITG.

[@mahdiehyari5564]

how can I use this model to calculate pressure drop over this tube ?

[@anjansamanta8593]

Can this simulation be performed on an i3 laptop?

[@dr.mohanadm-ridha1130]

Could you please if it is possible to simulate fluidized bed reactor solid liquid with adsorption isotherm model

[@dr.mohanadm-ridha1130]

Thank you

[@davidpatkovik648]

very nice video you give us, please continue giving us more about turbulent of water

[@pioneerofsuccess4054]

I would upload turbulent flow next month. Please be subscribed to get updates.

[@shafeeahmad5001]

Very very helpful ...thank you bro

[@meghamanojverma4112]

Hi sir your videos are really helpful...can you please help me to compute a 3D FBAR .

[@mohammedhamza8451]

hi, it's very helpful. Can you make a video shown how to add nanoparticles within the fluid to see the interactions between these particles

[@pioneerofsuccess4054]

I will make it shortly..keep in touch by subscribing to my channel

[@mohammedhamza8451]

I did long than time ago

[@mohammedhamza8451]

I sent you email too

[@pioneerofsuccess4054]

I will get back to you soon. Running through a tough schedule

[@av8176]

Hi, nice video. I have a question, it's impossible to find out how a periodic flow condition works for a 3D geometry. First, I tried for a 2D geometry with this condition U_0=2U_m s(1-s)(sin⁡(ωt)+√(sin⁡〖(ωt)^2 〗 )) and s goes from 0 to 1 along the inlet edge. In case of 3D condition, on a pipe, the inlet is a circle and that equation doesn't work.. Please let me know if you have any ideas because a have to finish my project in a few days and i couldn't find any solution yet. Thanks, Ana

[@pioneerofsuccess4054]

I will check and let you know.

[@jayarajj6514]

Error appears when I apply slip boundary condition at the walls. Wat to do?

[@dr.maheralibraheemi877]

hi sir ,its really great tutorial . would you make a new one bout laser drilling ? thank you

[@pioneerofsuccess4054]

Can you send me the the physics associated with that..I can surely help you

[@khalidhussain4792]

Nice person

[@ceyhunalekberli6265]

Can you do simulation for two-phase flow (oil-water) in vertical porous medium pipe?

[@pioneerofsuccess4054]

yes, it is possible. You need to incorporate gravitational force as a volume force. For porous medium, you need to incorporate Darcy's law.

[@ceyhunalekberli6265]

and what about boundary conditions? How pressure is changing over the pipe?

[@sabrinefadi6224]

thank you for your exemple I need a helpe to simulat a concentric cylinder in the inner ther is a watter flow and in the annular ther is a layer of phase change material and the outer cylindre there is a radiation solar

[@meghnasarmah6234]

sir, your videos are really helpful...can you please help me to compute a MIXTURE MODEL, LAMINAR FLOW (eg. water and water vapour )through a pipe?

[@pioneerofsuccess4054]

It would be nothing but a two-phase flow. You need to take water and a gas as materials and put properties of water vapor (viscosity. density). All other things would remain same.

[@meghnasarmah6234]

sir ....will it be same as this video except that instead of laminar flow we will take a mixture model for 2 phase?

[@pioneerofsuccess4054]

Do you want to model for turbulent flow? If so, you need to take turbulent two-phase flow. The model that would fit your problem that you need to find out from the available research papers. If you have other queries regarding modeling then you can email me.

[@meghnasarmah6234]

sir, i would be grateful if you would give me your email id.

how to know the outlet velocity value from simulation?

[@davidpatkovik648]

what is a viscosity and density of sewage ?

[@rajeet21]

can you teach us how to plot voltage drop and current drop in secondary coils

[@pioneerofsuccess4054]

Drop me an email mentioning all the the things in detail.

How to find shear stress ?

[@ram1010101]

Can you do it for turbulent flow

[@pioneerofsuccess4054]

definitely.. COMSOL gives separate module for that (Turbulent flow that comes under fluid flow)

[@iwizazazo4064]

Hi sir , can you do a modeling for rayleigh benard convection ,thanks

[@pioneerofsuccess4054]

We can try. Drop me an email. I will get back to you.

[@iwizazazo4064]

hi,thank you for your replying.I send you a mail to [e-mail]‬.thanks

[@susovanpal9937]

I want to give fully developed velocity profile at inlet. Can you help me with that?

[@pioneerofsuccess4054]

The term fully developed is not applicable at the inlet. We consider it as a plug flow when it just enters the pipe. After entering it undergoes wall friction and thus makes boundary layer. Stay tuned to our channel for more updates.

[@susovanpal9937]

Thank you for your reply. But I basically want to assign a velocity profile data in .csv or .txt extension at the inlet of a model of 2D open channel flow. is it possible to do in COMSOL?

[@pioneerofsuccess4054]

There is a simple way out. If you have the data file then you can easily generate an analytical function corresponding to that data in excel. Once you have this you can put it as a boundary condition.

[@susovanpal9937]

ok. I'll try that. thank you very much for your help.

[@susovanpal9937]

As you suggested I have created the analytical function (-2*(1^(-5))*y^2 + 0.004*y + 0.272) and put it as inlet boundary condition. but now I am getting error like this. "Failed to find consistent initial values. Last time step is not converged. - Feature: Time-Dependent Solver 1 (sol1/t1)" Can you suggest what may be the cause of this error.

[@abusyedsajib]

Thanks for the video,it was really helpful.I am trying to design a pipe with different diameter of inner and outer part.Can you please tell me how to design it??

[@ferdinafdo5857]

how to do mixing in 2D with turbulent flow

[@pioneerofsuccess4054]

There is a module named "turbulent flow"; you need to take that one. I will be uploading videos on turbulent flow shortly.

[@faaalsh8784]

How can I change the velocity during the simulation to show the change from laminar to turbulent flow

[@kanikajain532]

the viscosity of water is 0.001Pa.s

[@sabrinefadi6224]

thank you for your exemple I need a helpe to simulat a concentric cylinder in the inner ther is a watter flow and in the annular ther is a layer of phase change material and the outer cylindre there is a radiation solar
