The conventional rotary component for marine propulsion, the propeller, is not always simple. Some marine applications require variable-pitch propellers; some propellers must be adjustable for navigation in close quarters. The installation may take a nontraditional form, such as shrouded or ducted. Propulsion may come from a water jet system. The 21st century marine engineer will likely encounter a broad range of challenges.

A systems approach is the key to successful design. The breadth of high-fidelity analysis tools hosted within the ANSYS integrated platform provides the ideal environment for this challenging task.

Engineering simulation tools from ANSYS provide high-fidelity advanced physics that turbine designers need, whether the application is new machine design or machine rerating. The suite’s flexibility means the tools can be applied for operation in interactive mode or in batch mode within the design system of the manufacturer or consultant. The technologies are integrated within a common fluid dynamics and electronics software for which ANSYS is well known.
