Hi. For the past few months I have been modelling the movement of neutrally buoyant dye through a pipe with the species model in Fluent 5.5. I have found that altering the turbulent Schmidt number from 0.5 to 1.5 makes a 300% difference to the results. I know Fluent claims that a value of 0.7 is generally OK, but does anybody know if there is more detailed information for pipe flow. Thanks John
