I'm simulate spary. But i'm confused by several question .
1.what‘s the mean of injection velocity magnitude in particle injection regions?
I don't konw the difference bewteen injection velocity magnitude and injection direction (contions three velocity of x ,y,z).
Do they coincide with each other or are the same with each other?
2 why wall film can't be used in steady?
Equation dependent(set restitution coefficent ) isn't suitable for my model,
because particle can bounce ,spread and splash(because i simulate it at a constant temperature and cold-wetting surroundings)
Must i simulate it using Elsaesser Particle-Wall Interaction Model in transient simulate???
Transient simulate will greatly increase calculation
