You need to realize that it's not possible to get direct access to radial direction in Cartesian Coordinate which is native to Cylindrical Coordinate system.

The radial direction can only be...

Momentum source term in cylindrical geometry

If this momentum source term is constant, you need to enter this value to
cell zone condition--> fluid--> source term --> x and z momentum.

If this source term changes with velocity or any other...

momentum souce term

I don't think it should be a problem for cylindrical geometry. In cylinder, we need to define the axial and radial momentum source terms which I believe can be done specifying the source term in 'y'...

Trickle bed reactor_porous media

Hello Abhik,

1. Using backflow volume fraction is tricky in FLUENT for E-E multiphase flow. I suggest to use "dispersed phase" i.e. secondary phase volume fraction to set "0" at outlet.

Outflow...

Trickle bed reactor_porous media model

Forgot to mention that you need to calculate boundary conditions by solving "phenomenological models" - proposed any of those by Holub et al(1992,1993), Larachi et al (1990), Wammes et al...

Trickle Bed Reactor_mometum source model

Hello Avik,

Well, I've spent sometime to build up this model since this post however validation with experimental data is still pending. The porous media model can be built using both "viscous and...

Adding momentum source terms in multiphase eulerian simulation

Hello All,

I'm carrying out multiphase eulerian simulation in porous media to estimate pressure drop and liquid hold up. Addition of momentum source terms in both the phases (gas & liquid) have...
