Hi,
Could you please help me to get smth like that?
Can solidworks do that? Can i apply gas pressures and temperatures like that on a material face? I will use this method to find out the temperature dist. over an engine main frame (combustion chamber)
this sounds more like a solidworks simulation issue vs solidworks flow simulation in flow you wouldn't set those temps/pressures. you'd let the software figure them out.
in solidworks simulation, just craete splitlines to break the faces and then apply the BCs to those faces as you have outlined in your model. just be warned that you'll have discontinuities at those splitlines and you'll have to pay attention to how those discontinuities will affect the results.
Thnk u for reply,
Yes, i had figured out spliting method. But i cant identify the gas properties, instead, i can identify only the surface temp of the solid face by using "simulation". But i need convection heat transfer between gas and the wall first (by divided faces), then conduction heat transfer between wall face and engine blok.
The text that has this pic says this analysis is done with NX NASTRAN. May be this gives idea.
This is an exp from literature.
After applying these properties, in fact, my REAL aim is to find this temp. dist. over the blok created by the hot gases. The problem is this: the gas pressure and temp varies withrespect to crank angle.
what are your inputs?
what are the outputs that you want?
I can give you whatever you want as an input, but all i need is temp. dist. over the engine blok. I have different temperature and pressure values for gas that is inside the engine blok withrespect to their "splited faces"
If you wanna try, u can just do it by imaginary values. Just divide the inner surface of a ring, then let the gas effect these faces with different temp and pres. values.
I'm stucked at how to do it. I managed to find some results but they didnt make me glad.
the purpose of flow simulation is to determine the pressures and temperatures from a flow
it seems like you already know that, so why not apply it to the system for your stress analysis? (on the split faces)
if you don't know that information or you want to solve it, you're over defining your problem by trying to import it. setup the flow problem and then export the information to solidworks simulation for the stress analysis.
Yes, i know gas properties (P,T) withrespect to crank angle. But my purpose is to estimate the temp. dist. over the metal blok caused by gas temp inside the metal blok.
After this, i will open some cooling passages where the temp is high
then just apply the temps on the inside surface in solidworks simulation as a thermal analysis, get the temp gradients in your part, and add cooling passages. re run the thermal analysis with a temperature applied at those cooling passages (coolant temp) and rerun to see what it does.
with that being said, a better simulation would likely be to use convection coefficients on the inside. to know what the convection coefficients are, you either need to know from experiment, back calculate or pull from a flow simulation.
