this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...

In this study, ANSYS-FLUENT packages are employed to simulate the turbulent flow around DTMB4119 propeller in open water conditions. In order to form a mesh, the multiple reference frame (MRF) methodology is used. The results are compared with the experimental results and a good conformity is obtained, which endorses numerical simulation. Furthermore, the  turbulence model is used, which is sup...

The development of any design support system (DSS) is complex. It depends on the task being supported and the organization that is going to use it including its present design practices. This paper describes the initial steps in developing a DSS for marine propeller design based on the process carried out at HSVA (Hamburg Ship Model Basin). We follow a structured approach for this development. ...

This paper introduces a control scheme to vector thrust in marine cycloidal propellers with non-zero forward speed, despite the presence of measurement noise and current-like disturbances. Cycloidal utilize 360° thrust-vectoring provide agile maneuvering surface vessels like tugboats double ended ferries, but have yet be utilized present-day unmanned autonomous vehicles. work strategizes low-le...
