Pacific Water Pathway in the Arctic Ocean and Beaufort Gyre in Two Simulations With Different Horizontal Resolutions
Download2019-01-01
Hu, Xianmin, Myers, Paul G., Lu, Youyu
A set of numerical simulations (with horizontal resolutions of 1/4 degrees and 1/12 degrees ) is conducted to study the Pacific Water pathway in the Arctic Ocean and the freshwater content in Beaufort Gyre. Passive tracer tags the Pacific Water entering through Bering Strait into the Arctic Ocean...

CO2 solubility in brine in silica nanopores in relation to geological CO2 sequestration in tight formations: Effect of salinity and pH
Download2021-05-01
Li, Wenhui, Nan, Yiling, You, Qing, Jin, Zhehui
Geological CO2 sequestration during CO2 enhanced oil recovery in tight formations is a technically and economically viable option to alleviate carbon emission. In tight formations, there existsare enormous number of nano-scale pores, which can be filled with connate and injected water. In...

Zhou, Kaiyu, Maugard, Vincent, Zhang, Wenming, Zhou, Joe, Zhang, Xuehua
Recent developments in ultrafine bubble generation have opened up new possibilities for applications in various fields. Herein, we investigated how substances in water affect the size distribution and stability of microbubbles generated by a common nanobubble generator. By combining light...

A coarse resolution model is developed to study the thermohaline circulation of the North Atlantic. This model is driven by the annual mean Hellerman and Rosenstein wind stress field, Levitus sea surface restoring temperatures, and Schmitt, Bogden, and Dorman freshwater flux fields (mixed...

The pressuremeter is a unique method for assessing directly the in situ shear stiffness of soils. However, the correct interpretation and application of the measured modulus must account for the relevant stress and strain level acting around the pressuremeter during the test. A method to correct...

An opportunity to re–examine the liquefaction potential of hydraulically placed tailings sand has been provided by the Canadian Liquefaction Experiment (CANLEX). As part of this experiment, undisturbed samples of tailings sand were recovered after freezing the tailings in situ. Examination of...

Abstract: The Berkeley trigger criterion for evaluating the potential for earthquake-induced phenomena in sandy soils is reviewed in this paper. The historical database comprising the criterion is reconsidered using a consistent ''weakest-link-in-the-chain'' approach. Revised plots of average...

Abstract: The initial state of a sand, defined by the void ratio and effective mean normal stress, can be used to predict its large-strain response. Laboratory studies have shown that the shear-wave velocity of a sand is controlled primarily by the effective confining stresses and void ratio....
