Electrical submersible pumps (ESPs) face enormous challenges in the petroleum industry while handling gas–liquid two-phase flow. The major difficulty is caused by accumulation of gas bubbles inside ESP-impellers, which results mild to severe degradation pump performance. Therefore, analyze influence entrainment and bubble size, a combination experimental numerical analysis performed on five-sta...

The working capability of multi-stage pumps, such as electrical submersible pumps (ESPs) handling multiphase flow, has always been a big challenge for petroleum industries. major problem is associated with the agglomeration gas bubbles inside ESP-impellers, causing pump performance degradation ranging from mild to severe deterioration (surging/gas pockets). Previous literature showed that two-p...

With the demand for turbomachinery to operate at higher speeds, loads, and power, fluid film bearings that support turbomachinery must be capable of operating in these more demanding applications. Thrust bearings operating at high speeds and loads can experience high surface temperatures and thin fluid film thickness. Typically, babbitt (white metal) is the bearing lining material for most turb...

Abstract Electrical Submersible Pump (ESP) is one of the major Artificial Lift methods that reliable and effective for pumping high volume fluids from wellbores. However, ESP not recommended applications with gas liquid ratio. The presence free inside pump causes performance degradation which may lead to problems or even failure during operations. Thus, it important investigate effect on under ...

The selection criteria for multiphase boosting options remain somewhat subjective and are frequently influenced by the vendors’ data, which may mask potential limitations of this emerging technology. Existing literature on multiphase pumping tends to focus on a certain pump type for a specific field application, but does not provide more-generalized criteria for the selection of multiphase boos...
