Scenarios of energy efficiency and CO2 emissions reduction potential in the buildings sector in China to year 2050 [PDF]

, 2018
As China’s rapid urbanization continues and urban dwellers become more affluent, energy use in buildings is expected to grow. To understand how this growth can be slowed, we explore four scenarios for Chinese buildings, ranging from a high-energy-demand ...

Numerical study on the effect of rim seal slot filleting on turbine endwall cooling

AIP Advances
In this study, the effect of rim seal slot filleting on turbine endwall film cooling performance is numerically investigated. For comparison with the baseline case, five different fillet radius and width (R/W) ratios are adopted, i.e., R/W = 1.25, 2.5, 3.
