In this paper, a numerical study on pressure characteristics of fluid passing through a configuration of sudden expansion with central restriction only and sudden expansion with central restriction and fence has been carried out. The two dimensional steady differential equations for conservation of mass and momentum are solved for Reynolds number ranging from 50 to 200, percentage of central re...

We present an experimental and computational investigation of time-varying flow in an idealized fully occluded 45 degrees distal end-to-side anastomosis. Two geometric configurations are assessed, one where the centerlines of host and bypass vessels lie within a plane, and one where the bypass vessel is deformed out of the plane of symmetry, respectively, termed planar and non-planar. Flow expe...

The unsteady two-dimensional flow of a viscoelastic second-grade fluid impinging on an infinite plate is considered. The plate is making harmonic oscillations in its own plane. A finite difference technique is employed and solutions for small and large frequencies of the oscillations are obtained. 1. Introduction. In the past two decades, the importance of non-Newtonian viscoelastic liquids hav...

Numerical simulation of threedimensional groundwater flow near lakes shows that the continuity of the boundary encompassing the local groundwater flow system associated with a lake is the key to understanding the interaction of a lake with the groundwater system. The continuity of the boundary can be determined by the presence of a stagnation zone coinciding with the side of the lake nearest th...

OBJECTIVE The research is aimed at investigating the developing rule and the relationship between syndrome differentiation in traditional Chinese medicine (TCM) and clinical factors of gastric cancer, so that it can be helpful to the clinical work and indicating the prognosis. METHODS We collected the medical records and the information of four diagnostic methods of 325 cases of gastric cance...

Die nicht-hegemonial verankerte EU-Interventionsstaatlichkeit im Herrschaftsmodus der (Selbst-)Disziplinierung stellt die Akteur*innen in Europäischen Union vor große Herausforderungen. Johannes Gerken widmet sich, aufbauend auf den Traditionslinien kritischer Europaforschung, dem durch Euro-Krise induzierten EU-Staatlichkeitsausbau und entwickelt ein eigenes begriffliches Verständnis EU-Staatl...
