V. The onset of flow instability for downward flow in vertical channels. Jour- nal of Heat Transfer, 118(3):709-714, 1996.Stelling, R.; McAssey, E. V.; Dougherty, T. & Yang, B. W. (1996). The onset of flow instability for downward flow in vertical channels, ASME Journal of ...
A downward or vertical flow-through rapid diagnostic device and assay are provided. The device comprises a test area and reagent storage area, which are linked via a channel. The test area further comprises a reaction zone and an absorbent zone. A capture reagent is immobilized on the reaction...
Experiments of flow pattern for vertical downward gas—liquid flow are reported. In addition theoretically based transition criteria for the flow pattern are presented. The experimental results compare resonably well with the theoretical model for the prediction of flow pattern in vertical downward flow...
three-position control valve 105 is shown, connected to control the flow of pressure fluid to the cylinder 104. Valve 98 includes a solenoid winding 106 to operate the valve for control of cylinder 104 in driving the press ram downwardly through the charger. Winding 106 is energized via a ...
摘要: An increase of wall shear stress as compared to single-phase turbulent flow was observed. The existence of the single-phase law-of-the-wall was proved for downward flow. A comparison of upward and downward bubbly flow structure was made....
a downward flow of mercury in a heated duct, affected by a coplanar magnetic field (directed transverse to the main flow and along the long side of the duct), is studied experimentally for symmetrical (two-sided) and asymmetrical (one-sided) duct heating, showing different flow behaviors in ...

Two-phase flow excursion instability especially for a downward flow in a narrow rectangular channel heated on both sides was experimentally investigated. Three test channels with different gap sizes (2.5, 3.3 and 4.1mm) for the same channel width (40mm), the heated width (30mm) and the length...
