Proc. ASME. IMECE98, Fluids Engineering, 153-162, November 15–20, 1998
Publisher: American Society of Mechanical Engineers
Paper No: IMECE1998-0998
... Abstract This paper presents the results and analysis of in-situ air and water velocities, concentration and their impact on other parameters of multi-phase flow such as flow patterns. Experimental data of in-situ physical parameters such as spatial concentration, mixture velocities...

... results. Then, the effects of refrigerant components and operating parameters on flow patterns, heat transfer coefficients and heat and mass transfer resistance are discussed as the ranges of mass flux, saturation pressure and vapor quality are 200–800 kg/(m 2 ·s), 2–4MPa and 0.15–0.90, respectively...

... with triangular cross section (200 μm × 573 μm). The experiment was conducted with the mass fluxes of 330.07–550.11 kg/(m 2 ·s) and heat flux of 14.5–411.3 kW/m 2 at an inlet temperature of 15°C. Four flow patterns including bubbly flow, slug flow, churn flow and annular flow were captured with the visualization...

Proc. ASME. IMECE2012, Volume 7: Fluids and Heat Transfer, Parts A, B, C, and D, 2971-2980, November 9–15, 2012
Publisher: American Society of Mechanical Engineers
Paper No: IMECE2012-89707
... with the available empirical correlations in the literature. A reasonably good agreement was obtained for both parameters with mean absolute errors as low as ±7.5% for pressure drop and ±15.6% for Nusselt number. Further, a qualitative comparison of various flow patterns against experimental visualization data...
