It has an upstream compressor coupled to a downstream turbine, and a combustion chamber in-between. (Gas turbine may also refer to just the turbine element.) This machine has a single-stage ... http://koolkampus.com/engineering-notes-2/mechanical/gas-turbine-combustion-turbine/ A centrifugal compressor, also called a radial blower, squirrel cage, or squirrel wheel compressor, consists of a cylindrical assembly of compressor blades mounted on an axle. The compressor operates by using the centripetal force applied to an air mass to achieve compression. Centrifugal compressors are used throughout industry because they ... http://koolkampus.com/engineering-notes-2/mechanical/centrifugal-compressors/ Axial compressors are compressors in which the fluid flows mainly parallel to the rotation axis. Axial flow compressors have large mass flow capacity and high efficiencies, but have a smaller pressure rise per stage than centrifugal compressors. Axial compressors are widely used in gas turbines, notably jet engines. Engines using ... http://koolkampus.com/engineering-notes-2/mechanical/axial-compressors/ The Carnot cycle is a particular thermodynamic cycle, modeled on the Carnot heat engine, studied by Nicolas Léonard Sadi Carnot in the 1820s and expanded upon by Benoit Paul Émile Clapeyron in the 1830s and 40s. Every thermodynamic system exists in a particular state. A thermodynamic cycle occurs when a system ... http://koolkampus.com/engineering-notes-2/mechanical/carnot-cycle/ The Rankine cycle is a thermodynamic cycle. Like other thermodynamic cycles, the maximum efficiency of the Rankine cycle is given by calculating the maximum efficiency of the Carnot cycle. It is named after William John Macquorn Rankine, a Scottish polymath. Processes of Rankine Cycle There are four processes in the Rankine cycle, ... http://koolkampus.com/engineering-notes-2/mechanical/rankine-cycle/ Condenser refers here to the shell and tube heat exchanger installed at the outlet of every steam turbine in Thermal power stations of utility companies generally. These condensers are heat exchangers which convert steam from its gaseous to its liquid state, also known as phase transition. In so doing, the ... http://koolkampus.com/engineering-notes-2/mechanical/condenser/ A fire-tube boiler is a type of boiler in which hot gases from the fire pass through one or more tubes within the boiler. It is one of the two major types of boilers, the other being the water-tube boiler. A fire tube boiler can be either horizontal or vertical. This ... http://koolkampus.com/engineering-notes-2/mechanical/fire-tube-boiler/ A water-tube boiler is a type of boiler in which water circulates in tubes which are heated externally by the fire. Water-tube boilers are used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats up water in the steam-generating tubes. In smaller boilers, additional generating ... http://koolkampus.com/engineering-notes-2/mechanical/water-tube-boiler/ A High Pressure Steam Locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 PSI (1.4 to 1.7 MPa). High pressure locomotives can be considered to start at ... http://koolkampus.com/engineering-notes-2/mechanical/high-pressure-steam-locomotive/ The first law of thermodynamics is a generalized axiom of nature in relation to the conservation of energy. The most common enunciation of first law of thermodynamics is: First law of thermodynamics "The increase in the internal energy of a thermodynamic system is equal to the amount of heat energy added to ... http://koolkampus.com/engineering-notes-2/mechanical/first-law-of-thermodynamics/
