Samenvatting
The vortex finder is an essential part in gas cyclones. In order to obtain a new vortex finder shape for minimum pressure drop, the discrete adjoint method is employed. The new optimum cyclone will save 66% from the driving power needed for the Stairmand cyclone. A new framework for the grid independence study using the adjoint solver and the grid convergence index is introduced. The proposed framework has been applied successfully on the optimum cyclone. A comparison of numerical simulation of the new cyclone and the Stairmand cyclone confirms the superior performance of the new vortex finder shape compared to the cylindrical shape. The results of this study open new era in the optimization studies of the gas cyclones by using the adjoint methods instead of the traditional techniques. Moreover, the computational costs for the grid independence studies will be reduced via the application of the adjoint methods.
