Simulate oil spill weathering with system dynamic model

Aihaiti KASIMU, Junran DONG, Yuan BIAN, Desheng WU

Frontiers of Engineering Management Pages 696-696 doi: 10.1007/s42524-019-0060-1

Abstract: Numerous oil spill fate and trajectory models have been recently developed to predict oil spill weatheringA system dynamic model is thus developed based on the most significant oil weathering processes, whichWe employ differential equations to describe these main oil weathering processes, which vary and haveConsidering the main oil weathering processes, our model provides a different method of predicting theSimulation results of oil properties and fates are also presented in this study.

wood dust type on mechanical properties, wear behavior, biodegradability, and resistance to natural weathering

Sawan KUMAR, Ajitanshu VEDRTNAM, S. J. PAWAR

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 6, Pages 1446-1462 doi: 10.1007/s11709-019-0568-9

Abstract: Further, the biodegradability and resistance to natural weathering of WPCs were evaluated following ASTMIt was noticed that the biodegradability corresponds with resistance to natural weathering; more biodegradableWPCs were having the lesser resistance to natural weathering.

Micro-alloyed Steels 一 Review and Prospect

Wang Yikang

Strategic Study of CAE 2000, Volume 2, Issue 2, Pages 77-82

Abstract:

In recent years, the GNP (General Gross National Production) of the major countries in the world shows apparent relation with their consumption of steel and the steel is reconfirmed as the backbone of the engineering materials. This is due to the fact that the steel making industry has been reformed perfectly by the high technique — Advanced Process Control System and brought out new steels with superior property as “high tech” steels. Micro-alloyed steel is one of the major high tech steels with largest market demand. Micro-alloyed steels are produced by the Advanced Metallurgical Manufacturing Process with addition of strong carbide and nitride alloying elements, i. e. , Nb, Ti, and V to refine their grain size in re-heating and to harden and toughen their matrix after rolling. There were developed the micro-alloyed steel of HW60R for the manufacture of large dumping trucks in open-mining, the line pipe steels of X52 ～ X65 for the construction of high pressure pipeline, and the micro-alloyed weathersteel for transportation container manufacture with great economic successes in China. In view of the micro-alloyed steels being environment conscious materials and the further development of high tough line-pipe steels, high strength ship steels and high tough SUF steel plate, the micro-alloyed steels are prospective in China in the 21 century.

Numerical simulation of micro scale flowing and boiling

Wen WANG, Rui ZHUAN,

Frontiers in Energy 2009, Volume 3, Issue 4, Pages 396-401 doi: 10.1007/s11708-009-0049-2

Abstract: Numerical simulations of flowing and boiling in micro channels are presented, including the modeling of bubble dynamics of nucleate boiling, and a description of the interface of two phases with the volume-of-fluid (VOF). The two calculated cases are compared with related experimental data in literature. Some simulated results are found corresponding well to the experimental data. The simulated results also show the details of 3-dimensional heat transfer and the flow in micro channels, which are helpful to the investigation of the mechanism of two-phase heat transfer and flow in micro channels.
