STAR CCM+ DISSERTATION

It could be more productive to start simply and develop the problem using one loop of the radiator and find the results for this case. The solid is the thickness of the radiator wall, probably only a few cells needed. March 20, If BCs are correct, you will see the resulting heating transfer to the fluid the same either way. November 6,

And there is a fluid around the solid containing the internal fluid. October 15, , The others are walls. October 11, , Add Thread to del.

December 15, The others are walls.

July 15, And there dissretation a fluid around the solid containing the internal fluid. Should i model the radiator that only one part of which?

Modelling a flow throught a radiator. Instead, the software has been coded to recognize that fluid-solid heat transfer will be going between these regions.

November 6, October 11, Can you post labeled screenshots on a website somewhere? Staf, 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.

October 15, If you are working with a different radiator please describe.

Disaertation BCs are correct, you will see the resulting heating transfer to the fluid the same either way. 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 model all three portions of this problem. Flow across the radiator would simply be the transfer of heat from the wtar to the fluid at a variety of heat fluxes and temperatures, validated from experiment.

However, it may not be stwr. Perhaps describe your radiator. The hardest part of this problem is the cad and making sure you have conformal mesh. October 10, If it is accomplished quickly and accurately, then expand the model to include more geometry. March 8, To be sure, run simulation with adiabatic and another with an HTC or temperature condition set.

The complete radiator and the heat exchange from internal fluid through solid to external fluid would be very interesting. Make it even more physical by including other solids nearby.

  NFWF BUSINESS PLAN

The time now is There are several approaches for this problem. Otherwise, create a connected, conformal mesh of these three regions with the latter being bounded by a farfield condition, i. The solid is the thickness of the radiator wall, probably only a few cells needed.

Add Thread to del. It has fluid region that is moving heat away from or to somewhere else, yes?

Then we will see what kind of radiator you are working with and may be able to provide additional suggestions. March 20, It could be more productive to start simply and develop the problem using dissretation loop of the radiator and find the results for this case. It has a solid that contains that fluid region.
