This study explores the physics of laminar planar hydraulic jump power-law liquids in a horizontal channel through shallow water analysis. The theory is supplemented and validated by numerical simulation performed phase-field method COMSOL Multiphysics. analysis applicable for shear thinning as well thickening reduces to Newtonian equations when flow behavior index (n) unity. analytical results are further with experimental data present study. steady state free surface profile conjunction...
Abstract
The paper investigates a planar hydraulic jump during thin film flow over two-dimensional obstacle spanning the entire width of horizontal channel. shallow water analysis supported by numerical simulations identifies drop and simultaneous jump-drop-jump phenomenon under certain conditions. A although observed for obstacles in macro-domain has never been reported flow. study, thus, establishes efficacy which, with novel solution methodology, predicts characteristics much less computational...
How gravity affects immiscible liquid co-flow is best illustrated through experiments in inclined conduits. In the macro-domain, leads to flow stratification while microscale, phase distribution practically insensitive conduit tilt. The influence of orientation intermediate scale conventionally known as meso-domain or milli-channel, although noted, has not been discussed earlier. present study, morphology experimentally investigated during up, down, and horizontal a biphasic mixture glass...
Study of liquid-liquid flow patterns in reduced dimensions is relevant under the current trends to miniaturize process equipment. The phase distribution results from interplay surface (dominant microchannels) and gravity forces larger dimensions). proposed analysis, based on minimization total system energy comprising kinetic, surface, potential energy, unravels influence wetting properties predicts range existence annular plug as well onset stratification with increasing conduit dimension....
Draining from a closed-top tube occurs by downward displacement of liquid air. The air volume grows inside the as an axisymmetric bullet-shaped finger similar to Taylor bubble observed in gas–liquid slug flows, and drains annular film between wall. present study investigates draining shear-thinning vis-à-vis Newtonian liquids circular millichannels. Numerical simulations using phase-field method suggest that both power law Carreau models give close predictions behavior investigated domain,...
A typical culinary setting involves liquid condiments with different constitutive behaviors stored in jars, bottles, pitchers, or spouts. In the dynamic kitchen environment, handling these might require pouring, drizzling, squeezing, tapping, demonstrating interplay of container geometry, fluid properties, and expertise. There is, course, occasional accidental toppling. We investigate combined effects surface confinement dimensions on short-time spilling pouring dynamics a toppled cuvette....
The study presents a generalized “shallow flow” analysis of natural planar hydraulic jump in power-law liquids. It is based on self-similar velocity profile defined as function flow behavior index, n, and shows significant improvement over the previous which assumed quadratic failed for n < 0.5. Thus, enables deeper understanding influence shear thinning vis-a-vis thickening liquids emphasizes that description adequate highly if parameters are valid range interest.
