The effects of chordwise deformation and the half-amplitude asymmetry on hydrodynamic performance vortex dynamics batoid fish have been numerically investigated, in which two parameters were represented by wavenumber ( $W$ ) ratio above longitudinal axis to that below $HAR$ ). Fin kinematics prescribed based biological data. Simulations conducted using immersed boundary method. It was found moderate enhances thrust, saves power increases efficiency. A large can also increase thrust...
The optimization of the water-entry strategy for cross-wing underwater vehicles has become a research hotspot in field engineering, and its process is quite different from that wedges cylinders. In order to address this problem, numerical model vehicle was first established based on CFD method. governing equations boundary conditions dynamic were defined, along with basic principles discretization turbulent flow equations. overset mesh VOF multiphase introduced, size independence analysis...
Flow around a tethered model of swimming batoid fish is studied by using the wall-modelled large-eddy simulation in conjunction with immersed boundary method. A Reynolds number ( $Re$ ) up to 148 000 chosen, and it comparable that medium-sized aquatic animal cruising state. At such high , we provide, best our knowledge, first evidence hairpin vortical (HV) structures near body surface three-dimensional high-fidelity flow field data. It observed small-scale are mainly formed through two...
In this study, numerical simulations are employed to investigate the hydrodynamic performance and wake topology of a swimming Rhinoptera javanica. The study is motivated by quest understand hydrodynamics median paired fin(MPF) mode with both spanwise chordwise flexibility. employ an immersed boundary(IB)-simplified sphere function-based gas kinetic scheme(SGKS) method that allows us simulate flows complex moving boundaries on fixed Cartesian grids. A computational model constructed based...
This paper presents the difference between vacuum pressure and pore reduction for preloading projects. The experimental results show that pattern of fluid flow under can be classified into three categories—a single-phase water flow, an air–water two-phase a air flow. field test reaches highest value at ground level measured gradients in vertical direction are approximately 11 kPa/m. It is demonstrated (i) treatment area cannot sealed does not need to airtight, (ii) mixture drawn out from...
Compared with conventional well, herringbone-like laterals wells can increase the area of oil release, and reduce number wellhead slots platforms, also greatly improve development efficiency. Based on threshold pressure gradient in heavy reservoir, applied principle mirror reflection superposition, distribution equation is obtained reservoir. Productivity model proposed by reservoir-wellbore steady seepage. The example shows that productivity great accuracy to predict wells. used analyze...
The current quadruped robots are designed based on the animals in natural world, and use complex control algorithms to realize movement walking of robots, which cause problems such as difficult design bionic high production costs. In order solve above-mentioned problems, this paper will a four-legged sports robot that can walk quickly, turn cross obstacles at low cost simple control. First, establish simplified threedimensional model motion three-dimensional specific mechanical structure...
