“…3 shows the four mesh types mentioned above along with their corresponding volume fraction contours, for the corresponding process circumstance of 𝑊𝑒 𝑖𝑛 = 0.003, 𝐶𝑎 𝑖𝑛𝑡 = 0.6, and 𝑅𝑒 𝑜𝑢𝑡 = 30. As noted by previous researchers (Bashir et al 2011;Liu et al 2016), the size of the elements used does not have a notable influence on the interface or the mechanism of breakup. Table 3 provides details about various meshes used in the study, including their statistics and the inner droplet diameter as shown in Fig 3 . This table confirms the claim made in the study that mesh independence is achieved, as the inner droplet diameter only shows a 1% variation between the smallest and greatest mesh resolutions.…”

“…The contact angle used with wall adhesion affects the composition of the bubbles. The chosen contact angle for the air phase's confluence with the water phase was 36º, that being compatible with the interface, as describe by in (Pham et al 2012) [31] and (Liu et al 2016) [32].…”

With depletion of oil reserve around the world, focus has been shifted towards deeper exploration in the field that is difficult to reach. Oil production rate is influenced by perforation density distribution's along horizontal wells, specifically in reservoirs with high permeability and low-pressure drawdown. This study investigated the behaviours of the total pressure drop, mixture’s superficial velocity, void fraction and liquid film thickness that occurs with various flow patterns (i.e., bubble, slug, stratified and stratified wave flows). Two perforation density conditions are studied, namely perforation density increase at outlet and perforation density increase at inlet. The friction factor was fulfilled through the perforated and unperforated horizontal wellbore. Production is greater with a perforated horizontal wellbore than with a smooth (unperforated) horizontal wellbore. The total pressure drop, mixture superficial velocity and void fraction increases with the air superficial velocity when the water superficial was constant. The liquid film thickness decreases when the air superficial velocity increased, while the pressure drops increase with increases of mixture Reynolds number. The liquid and air products increase when the perforation density increases at the inlet section (and decreased at the outlet section) of the perforated horizontal wellbore. It was noted that the air product increased with the air flow rate. Liquid product increases with the bubble flow as the transition point of the bubble/stratified flow decreased. Validation with experimental data, as well as data from other researchers show good agreement, conforming the reliability of the numerical code used in this study. The convergence between the results is good through the patterns (bubble flow, dispersed bubble flow, slug flow, transition bubble/stratified flow, and transition stratified/stratified wave flow).

“…Commonly, the primary phase is a continuous medium and a major component of the fluid. The secondary phase is a minority phase dispersed in the main phase [22], [23]. For the sake of investigating the multiphase flow, Volume of Fluent (VOF) model, Mixture model and Eulerian model are developed and integrated in Fluent software.…”

Energy efficient conversion and saving technologies have increasingly become areas of fierce competition among countries all over the world. As a vehicle power multiplier, the turbocharger advances the power output of the engine, but also increases the power consumption due to oil leakage, which aggravates the fuel energy consumption. This work aims to investigate the sealing performance and power consumption of the proposed novel centrifugal pump type oil flinger (CPTOF) to suppress the oil leakage and reduce the power consumption of turbocharger, thereby saving fuel energy. First, the flow characteristics of CPTOF and traditional oil flinger were compared based on the established oil-air flow numerical model. Then, the effects of oil slinging hole number Z, diameter dh and inclination angle α on pumping air performance and power consumption of CPTOF were analyzed. Finally, the structural parameters of CPTOF were optimized using the orthogonal table L9(3 4 ) and the results were verified through experiment. Results showed that the oil leakage of sealing structure was effectively prevented by the pumping air effect. Moreover, Z, α and dh also had significantly effects on the sealing performance and the power consumption, and the degree of influence raised in turn. The CPTOF with Z=16, dh=1.80 mm and α=0° had the optimum working efficiency, resulting in the average pressure drop being extended to 107 kPa and the power consumption being reduced by 33.05%.INDEX TERMS Centrifugal pump type oil flinger, turbocharger, pumping air effect, power consumption.
