Fluctuating Inlet Boundary Condition In ANSYS CFX
Hello Experts,
My Problem is that " How to Input Fluctuating Inlet Boundary Condition (Time Dependent Velocity/Inflow Turbulence/Transient Boundary Condition) In ANSYS-CFX??" Thank You In Advance. |

I tried to found out the Equation for that but can't get appropriate Equation for Time Dependent Velocity, if you have please post here or give any reference book/material... |

PS Equation for time dependent velocity: v = f(t). |

You can specify turbulence intensity at the inlet, will that work for you? Turbulence intensity is defined as u'/U, so e.g. 5% would be u' = 0.05*U. As far as I know there is no way of specifying time-varying fluctuations at the inlet unless you have measurement data and include it through interpolation functions.
CFX does not have any of the fancy turbulence synthesizers that Fluent has. |
