This work presents a numerical investigation of the fluid flow in first stage two-stage centrifugal pump with vaned diffuser. A computational dynamics (CFD) analysis is performed by using ANSYS-CFX software for wide range volumetric rates and also different rotor speeds. The results are validated against measured values pressure rise through impeller diffuser an overall good agreement. Nevertheless, not only best efficiency point evaluated numerically overestimated comparison but computed...
On-line identification of flow regimes is important in two-phase because hydrodynamics and adequate operation multiphase systems are highly dependent on the pattern. This work describes application an artificial neural network (ANN) to process signals measured by a conductivity probe classify them into their corresponding regimes. Experiments were performed adiabatic air–water upward rig. Some statistical parameters cumulative probability density functions (CPDF) bubble chord length used as...
Electric submersible pump (ESP) systems are commonly used as an artificial lift technique by the petroleum industry. Operations of ESPs in oil wells subjected to performance degradation due effect viscosity. To understand this a numerical study simulate flow three stages multistage mixed-flow type ESP operating with wide range fluid viscosities, rates, and rotational speeds was conducted. The problem solved using commercial computational dynamics (CFD) software. model validated experimental...
Abstract The use of hydrodynamic cavitation (HC) as a wastewater treatment and anaerobic digestion pretreatment is well‐known process. However, most the experiments have been done at laboratory scale using low concentration total solids in sludge treated. In this study, waste‐activated has mixed with pig slurry aim treating two wastes rich nutrients organic matter. HC studied not only but also industrial (up to 500 L), novel rotating device consisting rotor multiple teeth that rotate inside...
Abstract This work presents an experimental analysis of gas–liquid flows in a centrifugal rotor prototype. Pressure rise curves are evaluated considering wide range liquid and gas flowrates different rotating speeds. An innovative apparatus including dynamic sealing system, back illumination, filming frame reference is employed to visualize flow patterns at operating conditions. Volume fraction measurement bubble-size evaluation also taken into account. The allowed analyzing details the...
Electric Submersible Pumps (ESP’s) are multistage pump arrangements used in offshore petroleum production. Most of their applications subject to viscous oil pumping, which causes performance degradation with respect the regular service water and changes some characteristics related flow dynamics inside pump. The purpose this work is use CFD investigate numerically a semi-axial type ESP three stages operating fluids different viscosities. Both design off-design rates simulated, as well...
