[en] a) Objective: The master thesis will be focused on 2D/3D numerical investigations of flow field around marine propeller. The problems will be solved using the commercial code: FLUENT. The propeller geometry is known. Aspects of flow field around propeller blades, including global hydrodynamic performance, velocity and pressure distributions will be analyzed.
b) Content (preliminary): In the last few years, RANS codes have been rapidly integrated in the propeller design process and they are routinely used to predict marine propeller performances. The viscous flow around propeller blades can be derived from the fundamental equations of fluid flow, using adequate boundary conditions. Numerical Investigation of the Hydrodynamic Performances of Marine Propeller in steady flow will be approached in two ways:
- 2D flow computation
Using lifting line theory with lifting surface corrections, the propeller blade sections, the resultant velocities and the angles of attack (at various radii), will be computed. These results will be used as input data for a 2D numerical investigation of flow field around blade profiles. - 3D flow computation
The numerical simulation of 3D flow around marine propeller will be performed in two cases: first, the computational domain will be cylindrical, including all propeller blades. Second, the computational domain will include only one propeller blade and rotational periodic boundary conditions will be used to reduce mesh size. Using incompressible RANS computations with different turbulence models, the flow around marine propeller will be numerically simulated to find out the pressure distribution on the blades and to define the propeller hydrodynamic characteristics.
