Default smoke (fire simulation)
Posts: n/a
hi everyone, I am trying to simulate a fire and instead of simulating combustion, i want to release smoke from a surface. However, i could not find physical properties (density, viscosity, etc.) of smoke. does anyone has a suggestion? My main problem is i dont have necessary hardware (such as enough ram) to simulate combustion nor release number of species (CO, CO2, H2O, soot etc.) from a surface. Instead I am trying to find out what would be the viscosity and density of a typical smoke. Instead of releasing 4-5 different species from a surface, i just want to release air and smoke mixture into air. Since it would be impossible to duplicate chemical combination of a car fire, anything close to it would be enough for me. I hope it is clear. thanx much
