Experimental investigations on operating characteristics of a closed loop pulsating heat pipe

Yu WANG

Frontiers in Energy 2015, Volume 9, Issue 2,   Pages 134-141 doi: 10.1007/s11708-015-0354-x

Abstract: The operating mechanism of the pulsating heat pipe (PHP) is not well understood and the present technology cannot predict required design parameters for a given task. The aim of research work presented in this paper is to better understand the operation regimes of the PHP through experimental investigations. A series of experiments were conducted on a closed loop PHP with 5 turns made of copper capillary tube of 2 mm in inner diameter. Two different working fluids viz. ethanol and acetone were employed. The operating characteristics were studied for the variation of heat input, filling ratio (FR) and inclination angle of the tested device. The results strongly demonstrate the effect of the filling ratio of the working fluid on the operational stability and heat transfer capability of the device. Important insight into the operational characteristics of PHP has been obtained.

NITROGEN MANAGEMENT: THREE MAJOR PRACTICES IN CLOSING YIELD GAPS FOR AGRICULTURAL SUSTAINABILITY IN NORTH-WEST

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 4, doi: 10.15302/J-FASE -2020355

Abstract:

Agriculture faces the dual challenges of food security and environmental sustainability. Here, we investigate current maize production at the field scale, analyze the yield gaps and impacting factors, and recommend measures for sustainably closing yield gaps. An experiment was conducted on a 3.9-ha maize seed production field in arid north-western China, managed with border and drip irrigation, respectively, in 2015 and 2016. The relative yield reached 70% in both years. However, drip irrigation saved 227 mm irrigation water during a drier growing season compared with traditional border irrigation, accounting for 44% of the maize evapotranspiration (ET). Yield variability under drip irrigation was 12.1%, lower than the 18.8% under border irrigation. Boundary line analysis indicates that a relative yield increase of 8% to 10% might be obtained by optimizing the yield-limiting factors. Plant density and soil available water content and available nitrogen were the three major factors involved. In conclusion, closing yield gaps with agricultural sustainability may be realized by optimizing agronomic, irrigation and fertilizer management, using water-saving irrigation methods and using site-specific management.

Introducing Sea Water from Bohai Sea to West China And Controlling Desert and Sandstorm

Chen Changli

Strategic Study of CAE 2001, Volume 3, Issue 10,   Pages 13-21

Abstract:

An advanced way for controlling desert and sandstorm to protect, recover and expand wetland in north and northwest China is proposed in this paper. The necessary conditions for increasing precipitation in inner continental basin contain mainly three aspects ： westerlies, high mountains for condensation and broad wetland fog as vapour resources . A scheme of project is envisaged, which introduces sea water from Bohai Sea through north Inner Mengolia to Xinjiang. The target of the project is to recover and expand wetland in northwest China. It will produce economis and ecological benefits in the aspects.
