Abstract: The Vortex Method (VM) based boundary condition of Sergent (2002) was implemented in the general purpose CFD solver Fluent. It is shown that the VM offers a relatively inexpensive and accurate way to generate random fluctuations representing a turbulent flow field at the inlet. Since the generated velocity field is temporally and spatially correlated, it is a much more realistic representation of turbulence than the one obtained with a simple velocity distribution, using a random generator. Validations are reported for fully developed turbulent channel flow, pipe flow and separated hill flow.
