December 19, 2019 at 2:05 amSubhoSubscriberI am facing problem in modeling air filter placed in polluted air. I want to see dynamic behavior of porosity and deposited mass on filter when polluted air pass through it. For this in models section I have specified K epsilon standard viscous model and two types of injectors with two different particle size and run the simulation with pressure based transient simple scheme with time step 0.1s , but I am not finding any post processing parameters which shows the required parameters so that I can calculate life of any filter. Also in my simulation I am finding very high pressure and velocity at the entrance and exit of filter. Filter I have defined as porous medium with laminar zone and defined viscous and inertial resistance parameter from experimental data of pressure drop vs velocity. I am also not finding and proper tutorial and theory in Ansys Users and theory guide. If I am getting help in this regard it will be very helpful for me.
Thanks in Advance

Thanks for your quick reply Amine.
What I have understood from Particle residual time post process that it will give characteristic of particle but I am more interested to know about filter property. Like when polluted air is passing over filter medium some particle will stuck on surface and for this why filter property such as porosity, internal and viscous resistant will change. Slowly all pores of filter will be filled with particle and after some time flow will be stopped.
I will be highly obliged if you please give any suggestion regarding filter medium simulation.

Can you please guide me in customization. I am not finding any material for customization like this.
December 19, 2019 at 11:07 amDrAmineAnsys EmployeeYou won't find it. For general questions check customization manual. If you have access to customer portal you mind find something related.
