I am doing a corona simulation. But particles are not spreading.

      In my simulation particle injected from the surface of mouth, it should have spreaded to the room but the particles are dropping soon. I have used 2 inlets and one one outlet. The inlets have 3m/s velocity and the outlet is the pressure outlet. I have used water liqid as injection material. i Have ran the simulation for 1 sec. the room volume is 738m^3

      Hi,

      If gravity is enabled, heavy water droplets will settle fast. For testing, try to turn gravity off to see if they otherwise spread

      Yeah I have tried, still the particles are falling. How can I resolve it? 
      should I decrease the particle size or  increase the inlet, outlet velocities?

      Yeah I have tried without gravity, it is same. So I increased the velocity and decrease the diameter. And also I was doing the simulation for 1 sec, that could be a reason.

      I am running for 1 min now. Lettsee
