Javier Estrada ENG 1223 Brayton and Otto Cycle When you talk about the Brayton cycle‚ gas turbine engines should come up and when you’re talking about the Otto cycle‚ piston engines should also come up. These two cycles are the backbone of power generation. The theory of the two cycles goes all the way back to the 18th century. The Name Brayton comes from the American inventor George Brayton and Otto comes from German engineer Nikolaus Otto. Both these men changed the world and how we live life

Clausius statement. A larger quantity of heat (Q1 + Q2) is supplied to heat engine (by high temperature source at T1) Which produces net work output Wnet equal to Q1 and rejects an amount of heat Q2 to low temperature reservoir. The composite of two devices is shown in Fig. (b). It shows that the heat pump helps the heat Q2 to flow from low temperature reservoir to high temperature reservoir‚ whereas‚ the heat engine supplier back heat Q2 from high temperature reservoir to low temperature

presented which utilizes liquid nitrogen as the working fluid for an open Rankine cycle. The principle of operation is like that of a steam engine‚ except there is no combustion involved. Liquid nitrogen is pressurized and then vaporized in a heat exchanger by the ambient temperature of the surrounding air. The resulting high – pressure nitrogen gas is fed to the engine converting pressure into mechanical power. The usage of cryogenic fuels has significant advantage over other fuel. Also‚ factors such

annihilation. The idea of nanotech was conceived by a man named K. Eric Drexler (Stix 94)‚ which he defines as "Technology based on the manipulation of individual atoms and molecules to build structures to complex atomic specifications (Drexler‚ "Engines" 288)." The technology which Drexler speaks of will be undoubtedly small‚ in fact‚ nano- structures will only measure 100 nanometers‚ or a billionth of a meter (Stix 94). Being as small as they are‚ nanostructures require fine particles that

Lots of people worked in mines‚ mining for raw materials such as coal‚ iron ore and limestone to make iron and there were also quite a few copper mines around. The manufacturing industry/factory system became huge thanks to the invention of a steam engine. Factories had to be built as the new steam-powered machines were too big to fit in people’s houses. The factories were 2 or more stories high with a couple of windows for light. The rooms were very big and packed with rows upon rows of machines;
