Properties of numerical methods
The following criteria are crucial to the performance of a numerical algorithm:
1. Consistency
The discretization of a PDE should become exact as the
mesh size tends to
Time-stepping techniques
Unsteady ows are parabolic in time
use time-stepping methods to
advance transient solutions step-by-step or to compute stationary solutions

Finite volume method
The nite volume method is based on (I)
rather than (D). The integral conservation
law is enforced for small control volumes
dened by the computational mesh:
Integral conservation
Finite dierence method
Principle: derivatives in the partial dierential equation are approximated
by linear combinations of function values at the grid points

Dimensionless form of equations
Motivation: sometimes equations are normalized in order to
facilitate the scale-up of obtained results to real ow conditions

Introduction
Propuslion: Propulsion is the act or an instance of driving or
pushing forward of a body, i.e. ship, by a propeller (in our

a) Momentum Theory
It was originally intended to provide an analytical means for evaluating ship
propellers (Rankine 1865 & Froude 1885). Momentum Theory is also well known as
