The first and simplest would be to treat the radiator as a porous media. March 8, Modelling a flow throught a radiator. And there is a fluid around the solid containing the internal fluid. Then we will see what kind of radiator you are working with and may be able to provide additional suggestions. It has fluid region that is moving heat away from or to somewhere else, yes?
And there is a fluid around the solid containing the internal fluid. However, for a dissertation, I would not recommend this approach because it does not do justice to the abilities of the code, nor to your time spent on the dissertation. If it is accomplished quickly and accurately, then expand the model to include more geometry. Modelling a flow throught a radiator. To be sure, run simulation with adiabatic and another with an HTC or temperature condition set. All times are GMT Add Thread to del.
Modelling a flow throught a radiator.
October 15, Instead, the software has been coded to recognize that fluid-solid heat transfer will be going between these regions. BB code is On. It could be more productive to start simply and develop the problem using one loop of the radiator and find the results for dissertahion case.
Can you post labeled screenshots on a website somewhere? There are several approaches for this problem.
To be sure, run simulation with adiabatic and another with an HTC or temperature condition set. This is a good, quick solution to arrive at engineering results. If you are working with a different radiator please describe. Add Thread to del.
July 15, March 20, Dcm+ describe your radiator. Make it even more physical by including other solids nearby. The complete radiator and the heat exchange from internal fluid through solid to external fluid would be very interesting. All times are GMT Flow across the radiator would simply be the transfer of heat from the radiator to the fluid at a variety of heat fluxes and temperatures, validated from experiment.

December 15, If BCs are correct, you will see the resulting heating transfer to the fluid the same either way. It has a solid that diswertation that fluid region.
How should i model this panel radiator? November 6, The others are walls. And there is a fluid around the solid containing the internal fluid. Instead, the approach that would be more physical, more complimentary to your final product dissertationand more taking full advantage of capabilities of code would be to dissertaton all three portions of this problem.
The time now is October 11, October 12, If it is accomplished quickly and accurately, then expand the model to include more geometry. Otherwise, create a connected, conformal mesh of these three regions with the latter being disseetation by a farfield condition, i.
MODELLING PANEL RADIATOR IN STARCCM+
The solid is the thickness of the radiator wall, probably only a few cells needed. However, it may not be needed.
