Thermal stratification which is common in water bodies subject to such factors as the depth of body (a lake or reservoir, for instance), fluidity and local meteorological conditions. The stable thermal reservoirs will lead changes physical chemical properties well distribution aquatic creatures, hence leaving an impact on quality. Daheiting Reservoir was taken research object this study. Based ...

Abstract Through a field experiment on sandy beach at Pingtan, China, we propose the first model to characterize variability of apparent von Kármán parameter in thermally and sedimentologically stratified air flows. The shows that is negatively correlated flux Richardson number as well sediment transport rate. atmospheric stability can be either from thermal stratification or sedimentological s...

The Çaygören Reservoir was sampled monthly from February 2007 to January 2009 at three stations to determine the relationships between the chlorophyll-a (Chl-a) dynamics and soluble reactive phosphorus (SRP), nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), water discharge, water transparency, water temperature (T), specific conductance (SC) and pH. Thermal stratification occurred in the re...

The effects of chemical reaction, thermal stratification, Soret and Dufour numbers on magneto-hydrodynamic free convective heat and mass transfer of a viscous, incompressible,and electrically conducting fluid on a vertical stretching surface embedded in a saturated porous medium are presented. A similarity transform is used to reduce the governing partial differential equations into a syste...

HCCI operating window has two distinct boundaries of knock at higher load region and misfiring/partial burning at lower load region. Moreover, there is no conventional direct way of controlling combustion timing in an HCCI engine. In this research, experimental study were carried out to investigate the effect of thermal and charge stratification on expansion of the operating range of a natural ...
