An experimental apparatus was developed to reproduce the general characteristics of gastric motility, while supporting the use of a non-intrusive flow measurement technique (Particle Image Velocimetry).
The main objective of this research work was to characterize the mixing hydrodynamics of this reactor through the non-intrusive flow visualization technique of electrical resistance tomography (ERT).
Electrical resistance tomography (ERT), which is a non-intrusive flow visualization technique, was used to investigate the solid liquid mixing in an agitated tank equipped with a top-entering axial-flow impeller.
Non-intrusive flow visualization using photochromic dye activation is applied to study the near-wall region around individual and coalescing pairs of Taylor bubbles rising in stagnant kerosene in a vertical 25.6 mm ID tube.
This approach, however, is time-consuming, expensive, flow intrusive and requires a new set of tests for any modification in geometry, configuration, topography or load conditions, entailing additional time and expense.
His invention may very well lead to the society espoused by Friedman and Parekh, in which widespread encryption forces the government to accept a less intrusive role in information flow.
In addition to portals, researchers will often make use of consent cards or tokens in virtual worlds; this alleviates concerns that unannounced researcher presence is unacceptable, or, that a researcher's presence is intrusive to the natural flow and movement of a given locale.
This announcement did nothing to stem the flow of intrusive remarks, including comments about her weight gain, forced the family to prematurely announce the pregnancy and later feel compelled to announce their miscarriage.
To design more efficient film cooling geometries for gas turbines, non-intrusive measurements of the flow temperature, velocity and derived quantities like the turbulent heat flux are needed in well-defined, generic flow configurations.
The proposed method thus revealed to be a powerful tool for non-intrusive investigation of a complex flow pattern in a full-scale column.
The method provides a non-destructive and non-intrusive tool for studying multiphase flow for which rapid changes in fluid saturation in the entire flow domain is difficult to measure using conventional techniques.
