Jet impingement heat transfer – Part I: Mean and root-mean-square heat transfer and velocity distributions
Abstract
Impinging jets provide a means of achieving high heat transfer coefficients both locally and on an area averaged basis. The currentwork forms the first stage of a two part investigation of heat transfer distributions from a heated flat surface subject to an impinging airjet for Reynolds numbers from 10,000 to 30,000 and non-dimensional surface to jet exit spacing, H/D, from 0.5 to 8. In the present paper,the rel ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World’s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global ....etc

SOLAR HEAT ENERGY STORAGE IN PHASE CHANGE MATERIALS
ABSTRACT
Developing efficient and inexpensive energy storage devices is as important as developing new sources of energy. Energy storage can reduce the time between energy supply and energy demand, thereby playing a vital role in energy conservation. It improves the energy systems by smoothening the output and thus increasing the reliability.
This paper deals with storage of solar thermal energy in materials undergoing phase changes. PCMs, which include salt hydrates, ....etc

Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

Building an economical and competent resource for energy storage, plays a key role in energy conservation as it can cut down the time radically, for both energy supply and energy demand. This innovative concept as crucial as locating fresh sources of energy, can actually enhance the output of the whole energy system there by escalating its consistency.

In phase change materials (PCMâ„¢s) like the salt hydrates, paraffinâ„¢s, non-paraffinâ„¢s and eutectics of inorganic, the storage of solar heat energy, leads to compactness and de ....etc

Boiler Blowdown Heat Recovery Project Reduces Steam System Energy Losses at Augusta Newsprint


Summary
The boiler blowdown process involves the periodic or continuous removal of water from a
boiler to remove accumulated dissolved solids and/or sludges. During the process, water is
discharged from the boiler to avoid the negative impacts of dissolved solids or impurities
on boiler efficiency and maintenance. However, boiler blowdown wastes energy because
th ....etc
