THIART, G. D.  and  VON BACKSTROM, T. W.. Numerical Solution of Flow through Turbomachinery with the SIMPLEN Algorithm. R&D j. (Matieland, Online) [online]. 1992, vol.8, pp.1-10. ISSN 2309-8988.

The SIMPLEN algorithm for the numerical solution of convection-diffusion problems on nonstaggered grids is applied to two turbomachinery through flow problems. Incompressible flow only is considered, and the k-ε model is used to simulate turbulence effects. The first problem is that of flow through a propeller. Both a uniform and a shear approach flow are considered. The thrust and torque exerted by the propeller on the fluid are modelled as prescribed body forces. Good agreement between the numerical results and the corresponding results available in the literature is obtained. The second problem is that of the flow through an axialflow fan. Both an axisymmetric and a distorted inflow is considered. Blade element theory is used to model the thrust and torque exerted by the fan blades on the air. Reasonable correspondence with experimental results is obtained.
