The exhaust gas needs to be cooled down from 703K to 333K by spray cooling. The flow rate of gas is 8.7 m3 per sec at 1 bar pressure. The chamber for cooling is a pipe of diameter 500 mm and length of 2500 mm having two bends. The spray pattern for cooling is full cone and the nozzle is spiral full cone nozzle of spray angle 60°.

What is needed to calculate is the mass flow rate and the pressure of the water that needs to be sprayed inside chamber such that the temperature is reduced effectively and the orifice diameter of nozzle.

The model used by me is Realizable K-Epsilon model. The boundary conditions given by me are velocity inlet and pressure outlet.

Can anybody suggest me a way to find the above mentioned parameters.
