Y+ value in porous zone while modelling flow through porous media ?

I am modelling a flow through porous media using ANSYS Fluent. The flow through porous media is assumed to be laminar. Shall I need to check y+ value in the porous zone also?

How to Determine the amount of heat flux while imposing UHF conditions ?

I am simulating a pipe flow using water as working fluid under Uniform Heat Flux conditions. The ultimate aim is to calculate Nusselt number in laminar and turbulent regime of the flow. I am not...

What d you mean by Delta X+, Delta Z+ in grid requirment of LES?

Large eddy simulation grid requirement mention about Delta X+ = 100, Delta Z+ = 30 and y+ = 1. Y+ is known but what do you mean by Delta x+ and Delta Z+, x is streamwise and z is spanwise directions,

Is LES model suitable for simulating transitional flow in a pipe?

I am trying to simulate transitional flow in a smooth circular pipe using Ansys FLUENT. Is LES is suitable for transition flow modeling? if yes, which SGS model can capture the transition behaviour?

Do we need to check the y+ values for SST K W turbulence model during post processing and if yes, should the y+ value be `1’ everywhere on the wall?

In SST k omega model the flow is resolved up to the wall. For this the y+ =1. However, in some cases where the solution is converged and showing fairly good results, the y+ values...

How to calculate fluctuating velocity components (u' v' w') for turbulent flow in FLUENT?

I am trying a case in FLUENT where I need to calculate fluctuating components of the velocity. I RSM model for capturing turbulence. Can you suggest any method to get these components
