Porosity
 
Hi All, Anyone know how to define a porous medium using CFX 5.5.1

not possible. cfx 5.5.1 sux ;)

try using momentum sources, so you could define for example pressure drop at the flow region...

Hi Jan,

here an example how it might look like

SUBDOMAIN: porous

Coord Frame = Coord 0

SOURCES:

MOMENTUM SOURCE:

Quadratic Resistance Coefficient = 0.5*density*42300[m^-1]

END # MOMENTUM SOURCE

END # SOURCES

END # SUBDOMAIN

where 42300 1/m represents a zeta-value for the pressure drop.

Hope this helps,

Markus

Hi, Markus!

What's meaning 42300 for zeta-value? and how to use the program you describe in CFX5.1.1?

Thanks a lot!
