I would like to define a velocity inlet in 45-degree angle for my quenching multiphase flow (water and air) case in 2D. I have tried to give the axial and radial velocity to inbuilt system, however it does not give me the exact solution. Could anyone help me about it? Do I have to add a UDF file or is there any other tricks you could recommend?
Following pictures are my actual case and the velocity vector that I want:
Thanks for the help in advance,

Yes method is correct but I want the velocity of water is going like spray, so I need a converging velocity profile at the inlet. I have been trying it for some time but still couldn't tilt the velocity vectors in 45 degrees. Do you have any hint how to do that ? Thanks in advance

Why can't we see any vectors next to the jet?

This is the last version. I have done it via UDF code in axial velocity and gave the radial velocity as -10 m/s. However, my goal is to define the vectors to left from inlet. This is an axisymmetric case. Do you have any idea how to change the direction? Thanks in advance.
DEFINE_PROFILE(vel_profile, t, i)
real x[ND_ND]; /* this will hold the position vector */
y = x;
F_PROFILE(f, t, i) = -15 - y*sin(45);
