Simulating such multi-stage marine propulsors involves handling the interaction between the rear blades and the wake sheets of front blades. The wake sheet and blade geometry can intersect, which may lead to singularity and incorrect pressure distribution. Different techniques are proposed to allow a simulation without singularity. The results obtained with these techniques are presented, and their advantages and disadvantages are discussed.enhttp://rightsstatements.org/vocab/InC/1.0/Boundary element methodTandem propellerTechnikIngenieurwissenschaftenConference Paper10.15480/882.335510.15480/882.3355Fluiddynamik und Schiffstheorie M-8Other
