Calculations of drag coefficients via hydrodynamic cellular automata
نویسنده
چکیده
The drag coefficient, CD, of an arbitrary shaped object ca;; be calculated by twodimensional hydrodynamic cellular automata. Results spanning nearly four orders of magnitude in the Reynolds number (0.I < Re < 10~) are presented for a simple, hexagonal object, and good quantitative agreement with previous experiments on cylinders is obtained. Hydrodynamical cellular automata (IIDCA), also called "lattice gases", are believed to reproduce the physics described by the Navier-Stokes equations [1-6]. Many different researchers have shown during the

Numerical simulation of hydrodynamic properties of Alex type gliders
Simulation of an underwater glider to investigate the effect of angle of attack on the hydrodynamic coefficients such as lift, drag, and torque. Due to the vital role of these coefficients in designing the controllers of a glider and to obtain an accurate result, this simulation has been studied at a range of operating velocities. The total length of the underwater glider with two wings is 900 ...
متن کاملTranslational drag coefficients of assemblies of spheres with higher-order hydrodynamic interactionsa)
Calculations were made of the anisotropic translation drag coefficients of rigid assemblies of spheres in a variety of arrays, including lines, circular equilateral polygons, disks (polygons with a central sphere), and stacked squares. The objective was to compare results obtained using polynomial expansions for the two-body hydrodynamic interaction tensor truncated at the (a/r) 1 , (a/r)3, (a/...
متن کاملRole of hydrodynamic drag on microsphere deposition and re-entrainment in porous media under unfavorable conditions.
Deposition and re-entrainment of 1.1 microm microspheres were examined in packed glass beads and quartz sand under both favorable and unfavorable conditions for deposition. Experiments were performed at environmentally relevant ionic strengths and flow rates in the absence of solution chemistry and flow perturbations. Numerical simulations of experimental data were performed using kinetic rate ...

متن کاملتحلیل عددی نیروهای پسا و برا وارد بر بدنهی زیر دریایی بدون سرنشین UUV
When the body is running at fully immersed condition in viscous fluid, there are two components of resistance, i.e. frictional resistance and form drag. When it is near the free surface, the additional drag encountered to the body which is wave-making drag. This paper is presents the hydrodynamic performance of high-speed Unmanned Underwater Vehicle (UUV) in fully immersed condition. We did 100...
