Written by Japanese scienntist Tomoyasu Tanaka, from Cambridge University, i like this article because we can found basic of thermodynamic like The thermodynamic system and processesThe thermodynamic process is a process in which some of the macroscopicproperties of the system change in the course of time.The zeroth law of thermodynamics.If two systems are in thermal equilibriumwith each other,

Thermodynamic laws, entrophy and CPH Theory

2010-01-31T03:17:00.000-08:00

this document written by Hossein Javadi from Azad University, this article take a new at thermodynamics laws and entropy according the CPH theory.Heat energy in CPH theory In CPH theory, energy is same as matter with high speed. In the other word, energy moves with speed of light c, and matter moves with speed of v, that v < c.So, speed of heat is c, too, because it is a kind

Refrigeration is the process of removing heat from an enclosed space, or from a substance, and rejecting it elsewhere for the primary purpose of lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. The term cooling refers generally to any natural or artificial process by which heat is dissipated. The process of artificially producing extreme

Thermodynamic Analysis of Compressed Air Vehicle Propulsion

2008-04-18T23:46:00.000-07:00

by : European Fuel Cell ForumThe fist compressed air vehicles were built by Andraud and Tessié du Motay inParis between 1838 and 1840. Since then the idea has been tried again andagain, but has never reached commercialization. In recent years the Frenchdeveloper MDI has demonstrated advanced compressed air vehicles. However,the claimed performance has been questioned by car manufacturers

Selected Values of Chemical Thermodynamic Properties

Prepared by David R. Lide.Introduction The theoretical framework of thermodynamics was well established by the time NBS was founded, and certain important applications, such as improving the efficiency of steam engines, had been demonstrated. However, the broad application of hermodynamics to the design and control of industrial processes had to await the accumulation and organization of a large

The gas-turbine operates on the principle of the Brayton cycle, where compressed air is mixed with fuel, and burned under constant pressure conditions. The resulting hot gas is allowed to expand through a turbine to perform work. In a 33% efficient gas-turbine approximately two / thirds of this work is spent compressing the air, the rest is available for other work download more at http://

System and Boundary in thermodynamic

A thermodynamic system is defined as a quantity of matter or a region in space chosen for analysis, surrounding or environment is can defined as the mass or region outside the system or everything external to the system boundaryThe closed surface that separates the system from its surroundings, through which energy and mass may enter or leave the system.Boundaries can be fixed or movable

Fourier's law of heat conduction

2007-04-07T16:20:00.000-07:00

The basis of conduction heat transfer is Fourier’s Law. This law involves the idea that the heat flux is. Thermal conductivity, k, a property of proportional to the temperature gradient in any direction materials that is temperature dependent, is the constant of proportionality.Heat always conducts from warmer objects to cooler objects. The composition of a material effects its conduction rate.

Thermo History

Although various aspects of what is now known as thermodynamics have been of interest since antiquity, heat:formal study began only in the early 19th century through consideration of the motive power of work. Today the scope is larger, dealing generally with energy andthe capacity of hot bodies to produce , and with relationships among the properties of matter. Moreover, in the past 25 years
