1 sty 2014 · In this paper, a unified flow pattern classification for liquid-liquid flow is proposed. This classification enables the direct comparison of flow pattern maps for further analysis.
Circuit balancing valves (CBVs) combine a double regulating valve with a primary measuring element for determining and adjusting hydronic fluid flow in an HVAC system. CBVs are an effective means of ensuring occupant comfort in buildings incorporating hydronic heating or cooling systems.
1 kwi 2014 · By accounting for the fact that this flow map determines the types of flow patterns during flow through pipe bends with three diameters, i.e., d = (0.016, 0.022, 0.030) m, it can be recommended as a example map for forecasting various water–oil flow patterns, as well for other geometries of pipe bends.

24 sie 2020 · Figure 1 presents a liquid-liquid flow pattern map developed for mineral oil and tap water, featuring superficial phase velocities. Various other parameters have been employed in the construction of flow pattern maps, as discussed in Section 2.2.
1 kwi 1993 · Experimental data were determined for co-current air-water horizontal flow in a 0.0935 m i.d. pipe. The flow patterns were identified by a combination of visual/video observations, the pressure fluctuation characteristics and a detailed examination of the pressure loss and holdup data.
9 NOTE: Spears® recommends that Flow Velocities be maintained at or below 5 feet per second in large diameter piping systems (i.e. 6" diameter and larger) to minimize the potential for hydraulic shock. Refer to Spears® engineering section entitled "Hydraulic Shock" for additional information. Friction loss data based on utilizing mean wall dimensions to determine average
