Particle generation using DPM and tracking in fluent
I am simulating a room with a person in fluent. The room has an air inlet (boundary) and outlet(pressue outlet boundary). My aim is to find the number of particles (coming out of person's mouth) leaving the room when person talks. For this, i defined the periodic mass flow inlet boundary condition at the person's mouth to mimic the breathing rate ( 3.5 cfm) . Also, i am trying to use DPM for particle (water vapour) generation near person mouth. I want to generate a particle concentration of 100/cm^3 for every timestep 0.01 s and then track them. I tried to find the concentration option in injection tab, but could not find it.
Is there an option to give particle concentration as input ?
