How to define volume particle injection locations with User Fortran and Zero Slip Velocity?


From version Ansys CFX 10 on, the following CCL can be applied for volume particle injection. Note that the "Zero Slip Velocity" Option is not available in the GUI.

FLOW:
DOMAIN: Your Domain Name
PARTICLE INJECTION REGION: Particle Injection Regions 1
FLUID: Liquid Water
INJECTION CONDITIONS:
INJECTION METHOD:
Number of Positions = 1000
Option = User Defined
Particle User Routine = Uniform Injection
Particle Volume Injection Return Variables List =
Particle Position
END
MASS AND MOMENTUM:
Option = Zero Slip Velocity
END
PARTICLE DIAMETER DISTRIBUTION:
Diameter = 5 [micron]
Option = Specified Diameter
END
PARTICLE MASS FLOW RATE:
Mass Flow Rate = 0.1 [kg h^-1]
END
TEMPERATURE:
Option = Value
Temperature = 300 [K]
END
END
END
END
END
END
