Propellers -- Data processing Fans (Machinery) -- Data processing Dissertations -- Mechanical engineering Thesis (MEng) -- University of Stellenbosch, 1996. The objective of this thesis was to develop a program to analyse steady, incompressible flow through a ducted propeller or fan. An extensive literature survey directed the project towards a perturbation potential based boundary element (panel) method. The work of Lee was instrumental to the construction of the present method. A modified Morino Kutta condition was implemented, rather than the non-linear pressure Kutta condition as proposed by Lee which necessitates extensive iterations. Three FORTRAN 77 programs were written to implement the method and various test cases are presented that verify the results produced by the program. Some problem areas are identified. Comparison between results predicted by the program and experimental results for local variation of pressure, as well as overall performance for an open propeller, demonstrates the practical value of the present method. A detailed analysis on a ducted fan system indicates a large increase in thrust produced when the blade loading is high. Although the maximum efficiency of the fan is slightly decreased when operating in a duct, an increase in efficiency is predicted at off-design conditions.
