SprayFoam for Water Injection Into Plume
 

I have attached a figure so you may visualize what I want. The white dots and the arrows represents where I want the "spraying" of water to take place, aimed towards the plume with a 45 degree angle. Would this be feasible without reaction? I only wanna see how the water effects the velocity and the temperature of the outer plume flow.

The velocity of the rocket flow at the nozzle exit will be approximately 2.6k m/s and temperature will be around 2800K.

Kind regards,
LS
