“…It is noticed that the energy-loss coefficient (Kd) is directly proportional to the holdup ( Φ ) because of the increase of fluid viscosity with increasing Φ . In all cases the less coefficient decreases with increasing Reynolds as previously concluded in El-Askary et al [2].…”

“…Emulsion (oil-in-water) fluid flow in curved diffusers was first experimentally conducted by El-Askary et al [2]. They concluded that the outer wall pressure coefficient is higher than that the inner wall and the energy-loss coefficient, Kd, is found to be inversely proportional to Reynolds number, diffuser area ratio and diffuser curvature ratio.…”

Experimental and numerical studies on emulsion (oil-in-water) flow in rectangular cross-sectional area S-shaped diffusers have been carried out. The effects of different parameters including area ratio, curvature ratio, turning angle, flow path, inflow Reynolds number, oil concentration and emulsion status (stable/unstable) on the static pressure distributions and energy loss coefficient are considered. The numerical study is carried out using ANSYS R-15.0 software Fluid Flow Fluent (FFF) 3D with different turbulence models. The comparisons between the numerical results and experimental data show good agreement. The results indicate that the S-diffuser energy-loss coefficient is affected by the geometrical parameters of S-diffuser, and the flow parameters. The energy-loss coefficient for the case of stable emulsion is found to be greater than that of the unstable emulsion flow. A general correlation of energy-loss coefficient including geometrical and flow parameters for the validated studied cases of S-diffusers is developed in this paper.
