the subject we discussion about are nucleation and meta stable phenomena’s , superheat liquids , supercold liquids and meanwhile  applications of this liquids. all in all meta stable situation can occur in three condition: first while changing liquid phase to gas phase by heating , second changing liquid phase to solid phase by cooling , third while moving water stream in subsonic nozzles or su...

Utilizing the combined cooling, heating and power generation (CHP) systems to produce cooling, heat and electricity is growing rapidly due to their high efficiency and low emissions in commercial and industrial applications. In conventional CHP systems the deficit of the system power can be purchased from the grid. However, this system cannot be used as the standalone application. The hybrid so...

The purpose of this paper is to show that hemochromatosis which means too much iron or iron overload, is the cause of many far too many cases of irritable bowel syndrome (IBS) and may be the leading reason to test for iron overload or hemochromatosis in patients presented with IBS. Until now there hasn't been a cause of IBS stated, the way I understand it. Now in more and more cases, iron overl...

In order to analyze the heating and cooling conditions of high voltage motors of YKK series in starting process, the starting characteristics and ventilation systems are calculated. The starting characteristics calculation method is improved and compared with the static characteristic, dynamic characteristics come to more consistent with the actual situation. The calculation result of heating i...

Global warming has today turned to one of the most important environmental issues due tooveruse of fossil fuels, and it needs serious attention. Since the mid-1970s, an urgent needwas therefore felt around the world to reduce the use of energy for heating and cooling inbuildings. Using green covers, especially green facades, in appropriate environmentalconditions can be regarded as a method to ...

We model the thermal effect of young stars on their surrounding environment in order to understand clustered star formation. We take radiative heating of dust, dust-gas collisional heating, cosmic-ray heating, and molecular cooling into account. Using Dusty, a spherical continuum radiative transfer code, we model the dust temperature distribution around young stellar objects with various lumino...

jet impingement heat transfer is an effective and practical approach that is employed in many industrial processes where heating, cooling, or drying is required. details of the heat or mass transfer rate have been investigated both experimentally and numerically and can be found in the published literature. in most of the numerical studies, control-volume approach has been employed to solve the...
