Homework Equations
The Attempt at a Solution
i don't know how to start...
i want to import a designed geometry to ansys or comsol from proengineer but i can't.
(ProE Filetype:*.prt)
in ansys:
it gets no error but continues processing and becomes not responding...
in comsol:
it says" Internal error translating CAD model Output file could not be saved"...
the problem is :
the fluid with 5atm pressure and -50C flows through the pipe , the pipe is heated by heaters on its side and has constant temp 200C.
i want to find the required length to have fluid with 100C.
its 3D analize because it has a wavy shape (it's not straight) so i can't do it axis symmetric..
i create 3D pipe geometry in ansys workbench and i import it in ansys.
but i can't mesh it with element "FLUID116" ...
with witch element i can mesh instead??
tanx
ok
but how i can calculate film coefficient from nusselt?
i am using fluid116...
and has N1...N4 input.
can i change its options to change required inputs?
tanx...
hi minger
but all i have is nusselt, prandtl and reynolds numbers...
so i have 3 known factors but 4 unknown: N1,N2,N3 and N4.
it has not a unique solo...
Hi
i need to calculate nusselt number for stimulation of air flow in a pipe with 5mm diameter and the pressure is 5atm.
it should be in the form:
Nu = N1 + N2 Re^N3*Pr^N4
and i want to calculate N1,N2,N3,N4.
but i don't know how?
can anyone Help?
