simulation with flowsimulation

[cla88]

Bye to all,
I have to carry out the study with flow simulation of a pot for a wing-shaped plane; This muffler, warming up in its upper surface, becomes a self-supporting device, and I must really search through simulation that hides this fateful portance.
My problem is that I have a very limited knowledge of flow and that I have a very close deadline, which adds the fact that I have no material people to put this problem directly to help me, so I ask you that you are my only hope.
who was interested or had ideas also contact me via private message for files etc.

thanks to anyone who wants to try

Could you explain the phenomenon better?

look practically inside the wing we send exhaust gases to the upper inner surface, to a temp of 950°c; in the image I posted before there is only the marble part, which is what I have to study at the cfd.
In fact, for the system of pipes and inner chambers, which have the primary function of silencer, it happens that the exhaust gases lose energy and then assume that they arrive at the lower internal surface for example at 750°C.
therefore as boundary conditions we place temperatures for internal surfaces, even if I have to do the analysis of the external flow.
This delta t should allow me in practice to get a self-supporting device (the pot should be installed on a small plane), that is to say that the pot is as if to those certain conditions of use in flight weighed 0....so that engineeringly I explained myself by dog but it is a concept a messed up wire.
what I can't do is get a simulation that shows me the force of portance (for example getting a chart?) and shows me the flow of external air that invests the object, stating precisely this difference of temperature that is what creates the game.
I hope I've been clear enough

I should have understood. If I can make a simulation in the day and then I'll let you know.

Thank you for helping me! !

I'm sorry if I interfere with your discussion, but I'm interested in the subject.

I should perform some analysis on a pneumatic cylinder system, and want to have some material and confirmations to be presented at a project meeting.

the question is: is it possible, having the 3d design of the cylinder, generate pressure in the cylinder chambers and verify the feasibility of the system? if it is possible you can tell me how to do it, unfortunately flow I never used it, and I don't have much time to devote to it.

thanks to all

Bye-bye

for what I can understand I think that in your case you should use simulation and non flow simulation because with the first you can apply the loads (pressions in this case) on the faces of the model then do the study and get as are the stresses, so depending on the material you choose see whether it holds or not
