Gas turbine and nuclear power
The gas turbine engine, essentially a jet engine coupled to a turbine that is geared to a propeller shaft, appeared to have found a niche in commercial ship propulsion about 1970. However, the fuel…
Detonation or Knocking in IC Engines
Detonation or knocking in I.C. Engines - The loud pulsating noise heard within the engine cylinder of an I.C. engine is known as detonation (also called knocking or inking). It…
Difference between 2 stroke and 4 stroke Engine
The stroke of an engine is referred to the distance covered by the piston from the top dead center to the bottom dead center. If the piston moves two times…
Propulsion and auxiliary machinery
At the beginning of the 20th century the near-universal ship-propulsion device was the reciprocating steam engine, furnished with steam from fire-tube boilers in which coal-combustion gases passed through tubes immersed in water. Turbine…
Engineering Materials – Introduction
The knowledge of engineering materials and their properties is of great importance for a design engineer. A design engineer must be familiar with the effects which the manufacturing processes and…
Factors affecting material properties:
Heat treatment: Heat treatment is used to control heating and cooling of the metals to change the properties and also to improve the performance or to enable processing. For example:…
Ship motions in response to the sea
In manoeuvring, a ship experiences yaw (rotation about a vertical axis) and sway (sideways motion). More generally, motions are possible in all six degrees of freedom, the other four being roll (rotation about…
