Flow pattern map
WebHowever, cross sections without vertical exaggeration are required when attempting to interpret groundwater flow directions. Maps are already scaled equally in the x and y direction and are most commonly used to represent two-dimensional groundwater flow patterns. An example of the process used to construct equipotential lines is illustrated in ... WebTwo-dimensional flow pattern maps serve to visualize the most likely liquid-gas flow pattern found in a section of constant diameter, inclination, fluid properties, and input volumetric gas and ...

A flow regime is identified based on the Froude number of the mixture (Fr m) and input liquid content (no slip liquid holdup C L). Fr m = v m ²/ g.D. where, v m is …
WebApr 12, 2024 · The flow pattern classification map shows that the boundary constraint increases the Reynolds number required to generate the turbulence flow pattern, and the range of the Reynolds number in the flow pattern of the laminar vortex street has a maximum increase range. The correlation between the time-averaged drag coefficient or … WebJun 15, 2024 · Flow patterns in the channels packed with metal foams occur in different conditions from the ones recorded for empty channels so gas−liquid flow maps developed for empty channels cannot be used to predict analyzed flows. A new gas−liquid flow pattern map for a channel packed with metal foams with the porosity of 0.92–0.94 was developed.
WebFlow pattern maps are presented in two ways: mass flux-quality as coordinates, and superficial velocities as coordinates. The quality range of experiment is from 0 to 1 thermally. Mass flux varies from 50 to 250 kgm-2s-1. Flow patterns are classified as: plug/slug flow, transitional flow, and annular flow. The quality of boundary between two ... WebOshinowo-Charles (Oshinowo and Charles, 1974) suggested by experiment that the flow patterns depend on the volumetric flow rate of the gas flow and other fluid dynamic …
WebJun 1, 2015 · The flow pattern map has the disadvantage that several dimensionless ratios are plotted versus the Martinelli-Parameter. Depending on the transition curve, the y-axis is a modified Froude number, the product of the modified Froude number and the square root of the Reynolds number or the ratio of pressure drop to hydrostatic pressure. Thus, the ...
