Plate heat exchanger modeling
 

Hi, I am trying to model flow between parallel plates. However the velocity and temperature profile are not consistent with theoretical one. If anyone did such a model, can you give me the dimensions of the plates and the boundary conditions. Thanks

From your description it sounds like you are trying to simulate plane channel flow. There are turbulent flow examples in the turbulence model section of the PHOENICS flow library of examples. I believe that there is also a library example for laminar fully-developed flow in a plane channel.

hello sir,

i am planning to model plater heat exchanger, can u give me details of ur model

with regards santosh tatepalli

It is 2D flow. I am trying to solve milk protein deposition on the surface. I need velocity, temperature profile and mass transfer at the boundary layer. This program is difficult to understand for me. I am trying from simple case without mass transfer. Thanks for your offer. Regards Ozlem

send me the mathematical model equation of heat exchanger for modification and emprovement works

Re: Plate heat exchanger modeling
 

Hello sir,

you may fabricate plate heat exchanger for practical validation ,then you can compare with simulation readings using Fluent .

Dear Ozlem,

For me there is still no clear statement of your problem, ie laminar or turbulent flow, thermal boundary conditions, nature of the discepancy with theoretical results, etc. There have been several applications of PHOENICS to plate-heat exchangers, including:

Kim S & Mills AF. Modeling of perforated plate heat exchangers. The PHOENICS Journal of Computational Fluid Dynamics and its Applications, Vol. 4 No. 1, pp 1-26, 1991. 91/11

Beale SB. Laminar fully developed flow and heat transfer in an off set rectangular plate-fin surface. The PHOENICS journal of Computational Fluid Dynamics and its Applications, Vol. 3, No 1, pp 1-38, 1990. 90/

I mention these papers because they appear in the PHOENICS Journal, which should contain the input and any ground files.

I hope this helps.

hello. How can we model a flow over a "fin with different temps." in ansys in order to find flows temprature & find mean "h"?? thanks.

I want to information about plate heat exchanger modeling

Re: Plate heat exchanger modeling
 

please sent technical data

Re: Plate heat exchanger modeling
 

You can find a comparison in Int J. Heat and Mass Transfer. 48, 15, 2005, pp. 3256-3260. There is good agreement between the CFD results (using PHOENICS) and the traditional solution for the eigenvalue problem.

dear sir i want reaserch paper on Plate heat exchanger modeling

Re: Plate heat exchanger modeling
 

respected sir

i want information about how to model plate type heat exchanger in CFD . so it is benificial to me if i got paper on it.

Re: Plate heat exchanger modeling
 

hello i am student of university. i need to information in the plate heat exchanger ,becouse of my project in the power plants lesson . please send me information if you can.

Worm Regards

hi sir, Am a student of PSG college of technology in india.Am currently carrying out a project regarding he numerical simulation of an heat exchanger.So in this regard i request you to send me papers on the same.

thank u'
