Fluid Mechanics in Naval Architecture, Ocean and Marine Engineering

These flashcards cover essential vocabulary and concepts in fluid mechanics related to naval architecture and marine engineering.

Fluid Properties

The properties of fluids include density, viscosity, specific gravity, and units.

Hydrostatics

The study of fluids at rest, focusing on pressure, Pascal’s law, and buoyancy.

Bernoulli Equation

A principle that describes the conservation of energy in fluid flow; applicable in incompressible and inviscid flows.

Cavitation

The formation of vapor bubbles in a fluid due to local low pressure, which can lead to material damage.

Reynolds Number (Re)

A dimensionless number used to predict flow patterns in different fluid flow situations, indicating whether flow is laminar or turbulent.

Froude Number (Fr)

A dimensionless number that compares the speed of a fluid to wave speed, important in ship hull design and open channel flow.

Dimensional Analysis

A method used in fluid mechanics to check the consistency of physical equations, often using the Buckingham Pi theorem.

Pitot Tube

An instrument used to measure fluid flow velocity by comparing stagnation and static pressure.

Flow Types

Flow can be classified as steady (unchanging with time) or unsteady (changing over time), and uniform or non-uniform based on spatial variation.

Aquatic Energy Density

Energy per unit surface area of waves; significant wave height is a measure used to estimate this energy.
