This document summarizes the efforts of EMMI Rapid Reaction Task Force on "Suppression and (re)generation quarkonium in heavy-ion collisions at LHC", centered around their 2019 2022 meetings. It provides a review existing experimental results theoretical approaches, including lattice QCD calculations semiclassical quantum approaches for dynamical evolution quarkonia quark-gluon plasma as probed high-energy collisions. The key ingredients transport models are itemized to facilitate...
The objective of this paper is to assess the current theoretical understanding extensive set quarkonium observables (for both charmonia and bottomonia) that have been attained in ultrarelativistic heavy-ion collisions over two orders magnitude center-of-mass energy. We briefly lay out compare currently employed frameworks their underlying transport coefficients, then analyze excitation functions yields characterize nature varying production mechanisms. argue an overall coherent picture...
With k — ε turbulent model, non-cavitating performance of a pump-jet propeller was obtained by calculating RANS equations. The comparison between calculation results and experiment data shown that the numerical model method reliable. cavitating hydrodynamic it calculated analyzed with mixture homogeneous flow cavitation based on Rayleigh-Plesset equations sliding mesh. effects different inlet velocity ratio, number characteristics were studied. When occurred blades, thrust torque decreased...
The BWB-UG is a glider with smooth and integrated fuselage wing. Its lift-to-drag properties are some of the most significant factors affecting its performance. In order to improve hydrodynamic characteristics, method steady-stream active flow control (SS-AFC) proposed. computational fluid dynamics used numerically investigate SS-AFC BWB-UG. mechanism effect on characteristics revealed from field aspect. before after installing was simulated using FLUENT. results show that can effectively...
The rapid acquisition of flow field characterization information is crucial for closed-loop active control. proper orthogonal decomposition (POD) method a widely used downscaling modeling to obtain characteristics effectively. Based on the POD method, reduced-order model (ROM) constructed in this paper control hydrofoil blended-wing-body underwater glider (BWB-UG) with stabilized suction and blowing forces. Compared computational fluid dynamics (CFD) simulation, time required predict target...
In recent years, with an increasing interest in the underwater wave glider, which is propelled by converting ocean energy into forward thrust through flapping multi-foil, flapping-foil aerodynamics has become important and popular topic of research biomimetic field. However, due to complex marine environment, motion frequency low uncontrollable, amplitude are non-constant, make multi-wing fluttering flow field aircraft unsteady. Therefore, it crucial study propulsive characteristics...
The ocean current is a disturb force when the autonomous underwater vehicle (AUV) navigating in sea, it can induce position change of dynamic positioning AUV, so effect low velocity maneuvers torpedo-shaped long-distance AUV. appropriate motion math model for torpedo- shaped AUV was built and AUV's built. Than to maneuverability which motioning simulated. results simulation show that obvious different at depth or direction different.
As a underwater vehicle with new thrust mode, the glide had shown some enormous advantages. When it is moving, changes its motion trajectory through changing gravity, buoyancy and location of lateral wing. The many advantages, such as simple structure, low resistance, noise, high utilize ratio energy, can fit need manufacture cost, energy expend, long time navigation, so be used kind auto carry platform or surveillant platform.This paper presents dynamics model vehicle. has compressed body...
As a new type of underwater observation platform, glider is widely used in marine explorations and military surveys, most gliders are powered by their own batteries whose capacities limited. It therefore necessary to analyze the energy consumption glider.

In order to explore influence law mechanism control lift drag hydrofoil, which is profile glider, based computational fluid dynamics (CFD) method SST k-ω turbulence model, hydrofoil under different conditions studied, include three factors: angle, position ratio, as well states: no stall, critical stall over stall. Then in state...

The successful operation of an Autonomous Underwater Vehicle (AUV) requires the capability to return a dock. A number underwater docking technologies have been proposed and tested in past. allows AUV recharge its batteries, download data upload new instructions, which is helpful improve working time efficiency. During process, unsteady hydrodynamic interference occurs between device AUV. To ensure docking, it very important that hydrodynamics understood. In this paper, numerical simulations...
Superhydrophobic surfaces could repel water due to the capillary force associated with surface roughness, which has a large range of applications, such as underwater drag reduction, heat transfer enhancement, oil/water separation, and so on. However, engineering applications superhydrophobic rely on stability surfaces. In this study, hydrophilic metal mesh was modified be superhydrophobic. The resulting designed bowl capable holding without leaking boat floating top sinking. an impacting...
