Injection of Fuel
Hello Sir,

I am trying a simple model to understand the injection of fuel in an Engine cylinder. I have made a simple model with following co-ordinates: (0,0) , (84,0) , (0,99) , (84,90) and (84,99). I have named the part from the last 2 co-ordinates as inlet and the boundary condition as pressure - inlet and all other surfaces as walls but all my attempts to simulate the fuel injection have failed. Can you please give me some hints on how to proceed with the model?

But...first of all....are you using one of the implemented model of injection of Fluent??????

I am using the define -> Injection option. and I am specifying the start and end points of the injection (Here I am confused too as it asks me to enter the end point of injection, which we dont know and I am just assuming a value).

You could have a look to the tutorial 17 of Fluent....
