Abstract
The classical adage: “Less Noise __ More Sound” challenged our interest -whether if it is or not possible to model by numerical simulation a suitable prediction in terms of sound quality to discriminate between Consonant _ Dissonant _Neutral sound patterns. Ansys_Fluent CFD_CAA code was used (with a 1e -6 time-step for 12milon of hexahedral cells grid) in order to perform related gas-dynamic numerical prediction – in ventilation. We have started our investigations with a simplest designed flat plated blades (for a revers spinning centrifugal fan) –prescribing three different incremented blade disposal. We have set some monitoring points (at certain transversal sections). The LES model with FW-H mode predicted results, were first Fast Fourier Transformation converted, than we have processed them with Matlab –in order find the most relevant group (octaves)/musical notes, and finally to decide by the use of an dedicated Wolfram code –whether the predicted sound should experience psycho acoustic supportability (i.e.-perception).
