Numerical Simulation of a Three Bladed Marine Propeller in Steady and Unsteady State

Abstract:

In this paper the numerical analysis for an unstructured polyhedral 3bladed un-skewed propeller in steady and transient analysis is discussed and the results are compared with the experimental data. A moving reference frame method is adopted by creating an interface between the propeller and the domain for the rotation of the propeller. The hydrodynamic coefficients such as Thrust coefficient (K_t), Torque coefficient (K_q), circumferentially averaged axial, radial and tangential velocity are compared with the experimental data. The computational time for each simulation is compared and concluded that marine propellers consume less computational time in the steady analysis when compared with the unsteady analysis.
