Infrared and thermal imaging is a global area inspection technique that detects and measures temperature and temperature differences to detect indication of disbond, delamination, cracks, residual stress and other conditions that impact heat flow. IR images provides temperature maps. Thermography is the use of IR imaging and measurement camera to see and measure thermal energy. Thus thermography measures heat which is constantly radiating away from any surface. This method is attractive for diagnosis because of its safe and non-invasive nature. ....etc

Geo-thermal energy is an important type of energy source, which is now available for commercial use. Geo-thermal energy finds its application in different purposes were low temperature is required. It can be defined as thermal energy stored in the underground deposit of steam, hot water and hot dry rocks. Geo-hermal energy is one of the cleaner forms of energy available in commercial quantities. The use of this alternative energy source, with low atmospheric emissions, has a beneficial effect on environment by displacing more polluting fossil a ....etc

It is widely discussed fact that the world is facing an energy crisis. All our major resources of power are diminishing in strength and demand is increasing steeply. In a few decades world?s petroleum resources will be emptied. This fact had been made scientist all over the world to think of energy resources which are everlasting.(perennial, renewable) One big step to the exploration of such renewable energy source is the conversion of ocean thermal energy.


As we all know energy is the basic resource for the nation?s economic development. ....etc

Solar thermal power plants use the sun?s rays to heat a fluid, from which heat transfer systems may be used to produce steam. The steam, in turn, is converted into mechanical energy in a turbine and into electricity from a conventional generator coupled to the turbine. Solar thermal power generation is essentially the same as conventional technologies except that in conventional technologies the energy source is from the stored energy in fossil fuels released by combustion. Solar - thermal technologies use concentrator systems due to the high t ....etc

The fiber/matrix adhesion is most likely to control the overall mechanical behavior of fiber-reinforced composites. An interfacial reaction may result in various morphological modifications to polymer matrix microstructure in proximity to the fiber surface. The interactions between fiber and polymer matrix during thermal conditioning and thermal shock are important phenomena.

Thermal stresses were built-up in glass fiber reinforced epoxy composites by up-thermal shock cycles (negative to positive temperature exposure) for diff ....etc

Heat engines are based on considering various factors such as durability, performance and efficiency with the objective of minimizing the life cycle cost. For example, the turbine inlet temperature of a gas turbine having advanced air cooling and improved component materials is about 1500oC. Metallic coatings were introduced to sustain these high temperatures. The trend for the most efficient gas turbines is to exploit more recent advances in material and cooling technology by going to engine operating cycles which employ a large ....etc
