I am trying to compute the time taken by a solid to reach steady state(30cmX30cmX0.5cm) if I have constant heat flux bc on one of the surafaces of the solid(30cmX30cm on bottom) that is placed in an open ambient environment where there is only convection between other 5 faces of solid and fluid...
Hi All,
I am trying to understand equations used by CFD solvers in solving an external flow Natural convection problem.
I know for computing the density variation term in the momentum equation they have 2 approaches; 1 Boussinesq approximation 2. Ideal gas law.
I am pretty familiar with...
Hi All,
Why r triangular/tapered longtudinal fins more efficient than straight fins from a convection heat transfer standpoint? Could any one please let me know. I have done some literature search and all i could find is analyical equations which ay that trainagular/tapered fins are better than...
Are there any commerical cooling fin design software to determine optimal fin topology, dimensions of the fins and spacing between the fins and number of fins) for natural and forced convection cases?
I have looked up online not able to find any.
The fins usaally i see use rectangular cross...
Hi All,
I am simulating a steady state Natural convection heat transfer problem in Acusolve. The solutions seems to be not converging.
I have no idea what migght be causing the convergence issues.
I am experienced in Structural analysis and trying to learn CFD analysis.
I would really...
Hi All,
I hope all are doing good!
I had our lab do a test for heat transfer for a simple scenario. It is heat transfer from a top(outside) surface of a horizontal plate. The temperature of the ambient is around 23 C and temperature measured at 2 thermo couple points on the top surface of...
