Course description: Course objectives:
Knowledge of NavierStokes equations and the physical meaning of individual terms. Learning about the discretization procedures and numerical solution of the discrete equations. Getting familiar with turbulence modelling and turbulence models. Getting familiar with the methods of grid generation and commercial software package. Ability to critically evaluate the results of numerical simulations.

Enrolment requirements and required entry competences for the course:
No prerequisites.

Student responsibilities:
Attending the lectures and excercises and complete project assignment.

Grading and evaluation of student work over the course of instruction and at a final exam:
Project assignment, oral exam.

Methods of monitoring quality that ensure acquisition of exit competences:
Attending lectures and excercises, accomplishing project, oral exam.

Upon successful completion of the course, students will be able to (learning outcomes):
Analyze the water flow around the ship hull. Identify the main causes of reduced physicality in the numerical simulation. Compare different approaches of turbulence modelling, in order to choose the most favorable one. Prepare students to use a commercial software package in marine hydrodynamics. Analyze the quality of the generated grid of finite volumes. Investigate the effect of changing the geometric features of ship hull on the flow around the ship hull. Determine the validity of the obtained solution using the verification and validation studies. Critically evaluate the results of numerical simulation of viscous flow (project).
