Based on an effective energy conversion method between gas enthalpy and thermal radiation, a multi-layered type of porous air heater has been proposed. In the five layered structure which is analyzed in this work, there are five porous layers which are separated by four quartz glass windows. The main layer operates as a porous radiant burner that products a large amount of thermal radiative ene...

Now a day’s one of the critical issues in a thermal power plant is to improve the efficiency of individual equipment. The various works found in literature shows that efficiency and availability depends on high reliability and maintainability of the equipments. But in present scenario with the concept of e– maintenance reduces the overall maintenance cost. The use of intelligent fault detection...

In an internal combustion engine, the heat energy approximately one third of total fuel input energy is converted to useful work. Since the exhaust gas temperature is not equal environmental temperature, so lot of heat energy lost with hot gases. Also heat energy is lost in cooling of engine. If we recovered heat energy which lost in cooling instead on crankshaft as useful work, then increase t...

A 550 cm thermal neutron detector was constructed with five parallel sheets of 75 mm thick Li foil (95% enrichment) spaced 1.63 cm apart. Anode wire banks containing a plurality of anode wires were strung on both sides of each foil, six banks in total. The chamber was backfilled with P-10 proportional gas and over-pressured to 1.1, 1.5, 2.0, and 2.8 atm (111, 151, 202, and 284 kPa). The design ...

aIn the present study a 4-stroke 5hp diesel engine was tested with Diesel oil plus cottonseed oil blends. The blends in different proportions (10 to 50 percent by volume) were tested at constant speed of 1500 rpm. The said engine is operated at different loads and characteristics like Brake power, Brake thermal efficiency, specific fuel consumption etc. Engine performance for blends resulted in...

An ever-increasing drift of energy consumption, unequal geographical distribution of natural wealth and the quest for low carbon fuel for a cleaner environment are sparking the production and use of biodiesels in many countries around the globe. In this work, jatropha and karanja biodiesels were produced from the respective crude vegetable oils through transesterification, and the different phy...

Enlarged tetrasubstituted alkenes with high fluorescent efficiency and good thermal stability are constructed. They exhibit luminance up to 35,160 cd m(-2) and efficiency of 16 cd A(-1) in OLEDs.

in internal combustion engines, only about a third of the total fuel input energy is converted into useful work. if the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. the main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing cerium...
