Hello all, I'm having a problem with surface injection of nanofluid in discrete phase model . In injection I couldn't able to add al2o3 as a material?

I'm working with ANSYS fluent to run the DPM simulation of Al2O3 nanofluid to perform the sedimentation analysis. I have a problem setting up the surface inlet injection of al2o3 nanoparticle as a...

Why fluent y+ does not match the calculated y+ ?

Dear all, Currently I'm performing a 2D axisymmetric simulation with constant heat flux. I have adjusted y (wall distance) value in the unstructured meshing based on the y+ calculation (equal to...

Do we expect 25% increment in heat transfer coefficient for 1% Al2O3-water nanofluid for Re=10,000 to 100,000 when compared to water?

Hi all, I'm kind of stuck in my validation for Al2O3 water nanofluid. the correlations for Nusselt number from Pak and Choi; Xuan and Li and Maiga seem a bit strange for me to compare my numerical...

Should I have to consider same velocity and temperature for Eulerian model in fluent (1% Al2O3 nanofluid) ?

I know this is basic question. In Eulerian model the velocities and temperatures are different for continuous and discrete phases. In this problem: For single phase (1% Al2O3 - water...

Why Eulerian model gives unrealistic high temperature at the pipe outlet (Fluent; 1% Al2O3Nanofluid)?

Pipe dimensions: length=1m; diameter=0.01m Axi-symmetric model under constant wall temperature (350 K) (Inlet temperature = 293 K) Eulerian model Realizable K-epsilon (per phase) coupled solver...

How to fix fluent error: WARNING: 30502 cells with non-positive volume detected (floating point exception)?

Hi there, I'm working 2D axisymmetrical pipe groove (CFD) model with constant wall temperature. During the hybrid initialization, I have a non-positive element error along with a floating point...
