“…Many computational fluid dynamics (CFD) studies are conducted on gas-liquid flow. Some of the most common modeling approaches include the Eulerian-Eulerian model (Shu & Wilks, 1995;Yamoah et al, 2015;Zhang et al, 2019;Acharya & Casimiro, 2020), the volume of fluid model (Shu, 2003b;Laleh et al, 2011;López et al, 2016) and the mixture model (Shu et al, 1997;Shu, 2003a;Shang et al, 2015). In this study, the Eulerian-Eulerian model was used as a modeling approach to solve the ensemble-averaged mass and momentum transport equations for dispersed gases, as well as continuous liquids, allowing detailed modeling of phase interactions.…”

A multiphase flowmeter (MPFM) is used in the upstream oil and gas industry for continuous, inline, real-time, oil-gas-water flow measurement without fluid separation. An MPFM typically consists of phase-fraction (holdup) and velocity (or flow rate) measurements. It is desirable to have homogeneous flow at the measurement location so that the phase-fraction measurement is representative. A horizontal blind-tee pipe-section is often installed to homogenize flow in the downstream vertical Venturi-based flowmeters; however, little information is available on the effect of horizontal blind-tee depth (HBD) on flow homogeneity. In addition, the Venturi vertical entrance length (VEL) leading to the Venturi inlet from the horizontal blind-tee outlet is another design parameter that may potentially affect the downstream phase distribution. The phasefraction measurement principle requires liquid properties (e.g. water salinity). The local liquid richness makes the horizontal blind-tee an ideal location for measuring liquid properties; however, an excessive HBD may affect the reliability of the measurements of liquid properties, because local vortices may degrade liquid measurement representativeness if the local liquid velocity is too low. This study uses a computational fluid dynamics approach to evaluate the effect of HBD  Corresponding author.

“…The evolution of fish swimming skills can be traced back hundreds of millions of years, and the underwater bionics constructed by the human research community is only a product of modern times (Sfakiotakis et al 1999;Singh et al 2017;Acharya and Casimiro 2020). Therefore, the autonomous underwater vehicle (AUV) is a famous propulsion representative currently active in the field of applied fluid mechanics, and its development is inspired by the mobility of fish (Roper et al 2011;Wynn et al 2014;Singh et al 2019).…”

In this study, we proposed an underwater robotic swimmer integrating dual-actuated composite tentacles. We employed overlapping grid technology to manipulate virtual swimmers and performed simulations of incompressible viscous flow. To facilitate the distinction between three driving modes (the reverse, homologous, and interlace modes), the rear flexible module of the swimmer was divided into three components: thigh links, calf links, and caudal fins. The cooperative motion mechanism behind the double-tentacled module exhibited special hydrodynamic properties. Under the same kinematic parameters, the reverse mode exhibited the best energy-saving and propulsion effect, whereas the homologous mode was affected by lateral energy loss, thus resulting in the worst propulsion effect. However, the joint system exhibited anti-interference and spanwise flexibility. The interlace mode produced a certain error in the lateral displacement, and the propulsion efficiency was between the former two modes. Compared with traditional fish-like robots, the diverse actuation morphologies of the swimmer reported in this study exhibit extremely powerful self-propelled functionality, and its key features, including the geometry of an aquatic squid and the kinematics of the stretched body-caudal fin pattern, offer insights into the analysis of self-propelled hydrodynamics.
