要約

The present study evaluates numerically convection heat transfer of swirling flows in a cylindrical cavity with rotating top. The Generalized Integral Transform Technique (GITT) was used to obtain a hybrid analytical-numerical solution of the two-dimensional Navier-Stokes and energy equations in terms of streamfunction only formulation, in which the Boussinesq approximation was used for the buoyancy force. Results for the temperature and velocity fields were presented for different Reynolds and Richardson numbers in the range 100?Re?2000 and 0
