Is forced convection possible in pro/e

[ksarita20]

hi ,


i have a thermal analysis problem where i have to generate a forced convection. i know that the coffecient of the plate(h) changes with respect to the velocity of air flow. but i am not able to get how to enter this in pro/e.


i tried to define a convection boundary condition and tried to select temporial variation. but there i can specify the temperature variation with respect to time. but i want to enter the variation of coffecient of plate with respect to time.


BUt first of all is my aproach right! please help me how to proceed in pro/e.


thanks in advance

Sari,


Unfortunately there is no way to enter a convection coefficient as a function of direction. However, you can subdivide the surfaces were you are going to apply the convection coefficient creating surface regions and assigning a different confident at each location. Again this an approximation that may be able to get you useful results.

hi,


yaa i came to know about this.


But this is the first time that i am using thermal module. Is there any source where i can get an example for Transient thermal analysis.


THanks Luis for all ur replies,

Sari,


The PTC customer support website has plenty examples. I don't know if all your questions are related to school work or youare working with a company. If you are working with a company and they are paying maintenance you should have access to the support website.

hi


i do have access to the support , but i couldnt find a example with transient loads.

You meant by 'transient loads' the time right? because different from steady state thermal analysis performingtransient thermal analysis in mechanica allows you to enter a time(min, max ,and time increment)which you like to see results for.You can findone in mechanica help which comes with its installation.
