Follow up (course codes):

Detailed description of topics:

Explanation of several flow models  and their fluid mechanics properties (pressure, velocity, mass and volume flow, momentum, energy flow etc.) and fluid domain in contrast with aerodynamics

Modeling flow models into numerical flow models.

Elementary solutions for potential flow and how to use them for panel codes which used these elementary solutions. Greens' function theory.

Grid generation techniques and how to use them. Several numerical error in the developing stage, desing and applications stage

Application for numerical method: Viscous flow Diffraction, Wave making pattern

Remarks assessment, entry requirements, etc.:

All courses mathimatics, fluid dynamics and Resistance and Propulsion of ships of MT01,MT02,MT03

Learning goals:

To distinguish the several flow models and how to use them for specific numerical flow models around ships, propellers etc.  

To use elementary solutions for potential flow and how to use them for panel codes which used these elementary solutions. Greens' function theory.

To know which numerical application has to be used for a specific problem (e.g. a given flow around ships with or  without free surface flow (pressure distribution, constant velocity, area's etc.)

know which simplifications or linearisation have to  be used and which physic phenomena is used

know which boundary conditions have to  be used

To understand the numerical models based on potential flow with or without free surface flow and it's linearisation and RANS-code.

To make the student aware for (numerical) errors and how to resolve this kind of problems

Computer use:

Three  different numerical tools (Navier-stokes, Delffrac and Delkelv) have to be used

Design content:

Opti,alisatiom of hull forms
