This work shows the observed changes in sample permeability and fracture geometry that occur within a fractured piece of low permeability shale with different effective stress gradients applied to the plug sample. These observations were made using an in-situ micro-CT fluid flow imaging apparatus with a carbon fibre Hassler-type core holder. Changes within the preferential fluid flow path under...

4 Q B A multi-faceted instrumentation approach is described which has played a significant role in ob*ing fundamental data for two-phase flow model development. This experimental work supports the development of a three-dimensional, two-fluid, four field computational analysis capability. The god of this development is to utilize mechanistic models and fundamental understanding rather than rely...

During its near-ground hovering phase a Short Take-Off and Vertical Landing (STOVL) aircraft creates a complex three-dimensional flow field between jet streams, the airframe surface and the ground. A proper understanding and numerical prediction of this flow is important in the design of such aircraft. In this paper an experimental facility, used to gather validation data suitable for testing C...

Computational Fluid Dynamics (CFD) simulations of gas-solid flow through a positive low-pressure pneumatic conveyor were performed using Eulerian-Eulerian framework. Pressure drop in pneumatic conveying pipelines, creation and destruction of plugs along the horizontal and vertical pipes, effect of 90° elbows and U-bends on cross-section concentrations, and rope formation and dispersion were...

In simulating two-phase flows, interface normal vectors and curvatures are needed for modeling surface tension. In the traditional approach, these quantities are calculated from the spatial derivatives of a scalar function (e.g. the volume-offluid or the level set function) at any instant in time. The orders of accuracy of normals and curvatures calculated from these functions are studied. A ne...

Abstract In this work, the role of appropriate mixing for mercaptan removal from Kerosene using caustic soda has been investigated in the pilot scale. Static mixer at different condition has been used as a passive mixing tool to achieve proper mixing and consequently high performance of mercaptan removal. Two lengths of static mixer including 20 and 40 cm as well as two pitches 1 and 3 m...
