Study of Two Phase Fluid Flow in Water Wet Reservoir Rocks by Using X-Ray In situ Saturation Monitoring
Displacement of oil and water in porous media of reservoir rocks is described by relative permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...
متن کاملExperimental results from a preclinical X-ray phase-contrast CT scanner.
To explore the future clinical potential of improved soft-tissue visibility with grating-based X-ray phase contrast (PC), we have developed a first preclinical computed tomography (CT) scanner featuring a rotating gantry. The main challenge in the transition from previous bench-top systems to a preclinical scanner are phase artifacts that are caused by minimal changes in the grating alignment d...
متن کاملUltra-fast x-ray tomography for multi-phase flow interface dynamic studies
Use of X-ray CT (Computer Tomography) system has been extended from medical fields to a variety of industrial applications [1, 2]. Among them is the visualization of multi-dimensional void distribution of two-phase flow in tubes. Mitsutake et al. [3] and Morooka et al. [4] used medical X-ray CT scanners modified for void fraction measurement within rod bundles. The results were comparable with ...
متن کاملThe effect of focal spot size on the spatial resolution of variable resolution X-ray CT scanner
Background: A variable resolution X-ray (VRX) CT scanner provides a great increase in the spatial resolution. In VRX CT scanners, the spatial resolution of the system and its field of view (FOV) can be changed according to the object size. One of the main factors that limit the spatial resolution of VRX CT scanner is the effect of the X-ray focal spot. Materials and Methods: A theoreti...
متن کاملFlow Visualization by Conditional Sampling of a Single X-Wire Probe in a Very Long Run Experiment
Flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. They have played an important role in understanding the physics of the coherent structures' formation and evolution in the transitional as well as the turbulent regions of the flow fields. Howev...
