SINOPSIS

This present paper describes three dimensional computational analysis of complex internal flow in a cross flow fan, (CFF) with a special emphasis on the performance improvement by varying impeller and casing geometries, inlet and tongue clearance gaps. RNG k-ε two-equation turbulence model is used to simulate the model with unstructured mesh. Sliding mesh interface is used at the interface between the rotating and stationary domains to capture the unsteady interactions. Three impeller geometries, seven casing configurations and three inlet and tongue clearances are varied in the present study. The efficiency of the fan has improved from 59 % to 71 % and that of casing from 37 % to 61 %. Maximum energy transfer through the impeller takes place in the region where the flow follows the blade curvature.
