Hello everyone.

I'm new to ansys fluent.

I try to model a gasoline injection to cylinder filled with air. I want to analysed time of evaporation of gasoline drop.

I know temperature,pressure and volume of air, volume and time of injection of gasoline (0.5ms) and injector diameter (0.3mm). I want to use single injetion type.

Can anyone tell me:
1) what kind of model should I choose: discrete phase, multiphase, species .. to calculate evaporation using droplet particle
2) how to calculate velocity of particle
3) how long a time step should be taken,
4) where the air parameters (temperature, pressure) shoud be define.

Is there any tutorial to this kind of problem?

Thank you in advance for your answers.

Best regards.
