Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

INTRODUCTION: In thermodynamics, energy can be neither created nor destroyed (1st law): it is either converted to usable work or lost as waste heat. The second law of thermodynamics states that the total entropy (disorder) of a system will never decrease over time; that is, systems can only be at constant entropy or have increasing entropy. This may be restated by saying that there is an upper limit to the efficiency of the conversion of heat to work, as in a heat engine. From these principles of thermodynamics, it is clear that there is an upper limit to how efficient power generation can be at most power plants. Many power plants, including those fueled by fossil fuels, nuclear sources, geothermal sources, biomass, and solar thermal, operate by generating a source of heat (burning fossil fuels, reacting nuclear materials, using the sun’s rays, etc.), using this heat source to heat water to steam, and passing this steam through a turbine. When the turbine spins, power is generated.…
