A growing number of studies have focused on variations in vegetation phenology and their correlations with climatic factors. However, there has been little research changes spatial heterogeneity respect to the end season (EGS) responses climate change for alpine Qinghai–Tibetan Plateau (QTP). In this study, satellite-derived normalized difference index (NDVI) meteorological record from 1982 2012 were used characterize pattern EGS relationship temperature precipitation QTP. Over entire study...
As the centrifugal pump is running, fluid usually flows into impeller along shaft, and out radially by force of impeller. The mutual, so also subjected to reaction fluid, but distribution this on blades uneven. In addition, front rear shrouds are asymmetric, which main causes axial force. This paper adopts numerical calculation method studying mechanism at all stages multistage various working conditions, exploring formation shroud pressure differential blade twisting its variation laws...
Solar salt is the main heat storage medium for concentrated solar power plants. It will undergo thermal decomposition reactions to produce gas when temperature higher than 450°C. So that bubbles of are free in molten pump flow channel, which have serious impacts on internal and external characteristics pump. This paper takes 16ENH-2 high-temperature as research object. Based mechanism salt, we studied influence different generation rates bubble coalescence breakage phenomenon The results...
The structural parameters of the first stage impeller have an important influence on performance multistage pumps, and purpose our study is to find most significant factors affecting double-casing then carry out a comprehensive optimization hydraulic cavitation performance. With Plackett-Burman design method, we made notability analysis parameters, three control variables that are sensitive pumps were found. Based response surface carried central composite experiments for variables,...
It is an inevitable choice that intensive development of cities popular in Chinese urbanization procession, so ecological design building trend modern high-rise design. This article concerned with analyzing characteristics and environment the Lanzhou , understanding problems Lanzhou, puts forward a strategy on under cold climate conditions Lanzhou.
Balanced drum systems are widely used in high-pressure multi-stage pump axial force balancing mechanisms. When the working, fluid (solid-fluid mixture) collides with each other or rubs against case, and balance is affected by this situation for a long time, so wear of gap occurs from time to time. The first study how multistage changes at different sizes paper. Based on energy equation momentum equation, basis maintaining original unchanged, new resistance pressure difference relationship...
This article is focused on the issues of plazas in Northwestern China. Firstly, it analyzes a series ecological problems urban open space cold region. Therefore, proposes an appropriate strategy for spaces at base bio-climatic under and arid condition. Finally, taking Baiyin Jingyu Healthy Square as example, paper specific design method based conditions.
The axial force balancing capacity of a balance drum is key factor affecting the life multi-stage centrifugal pumps. At present, traditional calculation formula mainly obtained by modifying relationship between last-stage impeller head and total through empirical coefficient, result less sensitive to change clearance. However, many studies have shown that increase clearance main drum. In addition, cost measuring relatively high. Therefore, it particularly necessary derive mathematical...
