Heat pipe Simulation
 

Hi all,
recently, I got project to do simulation for it this project was multi-phase flow heat pipe vapor in core and water in wick structure and the heat pipe consist of 3 sections ( evaporator, adiabatic and condenser ), evaporator adding heat and condenser reject the heat .
my question is how 2 set these with Fluent

Hi friends no-body is expert in my case pls necessary ????

Hi if you find it ,please sent me ,i similar you try to solve heat pipe problems ,
i have a lotof file aboute the heat pipe,if you need i can sed for you please send for me your email

Okay Amir really thanks for ur offer
my e-mail is omer.adnan84@gmail.com

Hi Dear;
I think you must study some published Papers such as Faghri's work and his colleagues i.e. M.B.shafii, Y.Zhang. Just as I memorized They modeled phase change within wicked heat pipe by a CFD approach. However, no accurate method has been still published for this simulation. The model wich they used , in my opinion, is a general approximation.

Hello Dear, yes All these papers as you maintained useful but I couldn't get the method to simulate, these papers explain the wicked heat pipe with physical way I need to transfer this to Fluent there r multiphase choice inside Fluent for instant VOF, mixture, and Eulerian

sfx or cfx
 

i remember a person said that must be model with cfx or sfx (sorry i forghat actualy name) your wright in fluent has big problem for model the boiling the droplet to fluid (water)to vapor
my frind i dont have any model file ,i have a paper and book about heat pipe
do you have any program in matlab or anuther softwer for select a heat pipe?
similar this http://www.supersonicengineer.com/ :confused:

One way to model is to use UDFs and write correlations for boiling and condensation to predict the quality. Using that information (quality, Tsat,...), the adiabatic section can be reasonably modeled using VOF. It worked for me in COMSOL as the UDFs there can be written in MATLAB. I never worked with UDFs in Fluent.

I think u meant fix.c ,,,, dear if if u have tutorial pls send me okay thanks

yes dear now I reached to UDFs with fix.c but I need now more and more tutorials and manuals to achieve this by myself .... thanks

no cfx is new version of fluent -ansys 12
please search in google about it

Dear this software available but nothing new upon my issue .
manual and tutorials .

Hello to everyone.

I would want to know whether its possible to use the evaporation-condensation mass transfer equation to simulate the evaporation process of water to vapor and thus avoid writing a UDF for the same.

I've been simulating the flow but it seems its just natural mixing of water into air (temperature effects of boiling are not visible) even after setting the wall and flow temperatures above saturation. Any help would be highly appreciated.

Many thanks in advance.

Dear Amir
Could your please send me your file and UDFs for me?
Thanks for your kind attention

simulation of heat pipe (evaporation part)
 

Hi everyone, i am currently doing my undergrad and i get this topic (heat pipe) for my final year project...... Just wanna ask whether cfx or fluent is easier to use to model the boiling part of the working fluid in it. Any suggestion??

for the heating part, do i need to draw a heating medium to contact to the pipe?? or juz put the boundary condition of the heat pipe wall as heat flux in to serve as a heating source??

type of working fluid: water
type of HP material: copper
and there is very thin porous domain in the heat pipe to simplify things....

i'm running out of time, hope anyone in this forum can give some suggestion and guidance.... thanks in advance...

Heat Pipe
 

Hi everyone
i want simulate Heat pipe,with Fluent,But i dont Know haw simulate boiling working fluid in heat pipe?any body solve this problem or do this work?
plz help me....

I neeed to model a heat pipe in comsol
 

Hi
I really need to do this (modelling a heat pipe) as a part of my final project :confused:. I prefer to creat a model in Comsol. I would be grateful if you could help me.

question
 

hi
i am simulating a 2d assymetric pipe in comsol.when i have volume force(gravity) for my model ,comsol cannot converge but with out it i cant get good answers.anybody can help me?

Assalam Amir
 

I am working on a heat pipe. I am stuck in UDF part as you mentioned if i can get any help from you i ll be realyy helpfull.

Thank you, My mail id snadeembe@gmail.com

Dear Shahid

your heat pipe is wick or wick less ??

Hello Mohammed,
Its a wick heat pipe

at any program that you used it to solve case of heat pipe ex.Fluent,COMSOL,...etc?

Mohammed i am planning to USe CFX or Fluent. What is your suggestion on this

if use COMSOL program please inform me
i have video will learn you to solve heat pipe by COMSOL

Sure bro i would like to see that and try

Hi everyone,
I want to model a heat pipe and simulate it. So anybody who has already done it can send me the videos of the work. My mail I'd is saikiranvarma331@gmail.com

Help in simulation of heat pipe.
 

Anyone succeed to simulate the heat pipe evaporator and condenser?
I'm doing my bachelor project on it and i will appreciate any help in this case because, i'm beginner with fluent however, i know the equations of energy and momentum which need to be written in the UDF but i failed to simulate it.
My email : Abdelhamidkassem93@gmail.com
If anyone have udf or tutorials to help me in this case.

ask some question
 

hello, Muhammed, i am working on the simulation of loop heat pipe, and i want to use comsol to serve it and i want to know if it is feasible . and can you give me some advice and study materials, please? best wishes.

Heat Pipe simulation-Fluent-VOF-UDF
 

I succeeded in simulation of a 2d heat pipe using fluent 17 VOF multiphase model with hooking UDF with the case. :cool:

The UDF didn't work on Ansys 16 due to some bug in the program, you should use ANSYS 15 or 17 instead.

If someone need help in the simulation, write your email and i will send some good resources.

hello,i am simulating micro flat heat pipe,can you give me udf or detail about it .thx
