Design and analysis of propeller blade geometry using the PDE method [PDF]
, 1993 This thesis aims to incorporate geometric and functional design of surfaces using a method known as the PDE method. In particular, it will be demonstrated how the PDE method can be extended to represent an existing marine propeller geometry ...
