Vertical zigzag maneuver of a generic submarine

چکیده
A study of a 10/10 vertical zigzag maneuver the generic submarine Joubert BB2 is presented. CFD simulations, involving moving planes and rotating propeller using dynamic overset technique, are performed at constant rotational speed in model scale on four systematically refined grids compared against experimental data for depth, pitch, pitch rate, drift, velocity, absolute thrust torque coefficients. grid also self-propelled approach condition before starting maneuver, used to obtain speed, controller horizontal commands, boat attitude. The analyzed full 6, 10 15 knots. Results indicate that matches very well data, even coarsest grid, with RPS converging slowest grid. By comparing results, it can be concluded simulations good surrogate parameters related motions, but as expected forces strongly affected by operational point changes considerably. Analysis moments affecting control from hull, sail stern planes, hull help understand response vehicle.

Zigzag carbon nanotubes with generic electron-electron interactions
A Hamiltonian is derived for a zigzag carbon nanotube with an arbitrary number of weak electron-electron charge and spin interactions, which become significant in ultraclean systems. The renormalization group and bosonization are used to determine the ground-state phase diagram. Our phase diagram contains some exotic phases which have not previously been predicted in carbon nanotubes with physi...
متن کاملZigzag codes and concatenated zigzag codes
This paper introduces a family of error-correcting codes called zigzag codes. A zigzag code is described by a highly structured zigzag graph. Due to the structural properties of the graph, very low-complexity soft-in/soft-out decoding rules can be implemented. We present a decoding rule, based on the Max-Log-APP (MLA) formulation, which requires a total of only 20 addition-equivalent operations...
متن کاملThe vertical excursion of the body visceral mass during vertical jumps is affected by specific respiratory maneuver.
Most of the inverse modeling of body dynamics in sports assumes that every segment is 'rigid' and moves 'as a whole', although we know that uncontrolled wobbling masses exist and in specific condition their motion should be optimized, both in engineering and biology. The visceral mass movement within the trunk segment potentially interferes with respiration and motion acts such as locomotion or...
متن کاملThe Second Conference of Global Chinese Scholars on Hydrodynamics Direct simulation of zigzag maneuver for fully appended ship
In this paper, a CFD-based method coupling with overset grid technique is used to directly simulate the 20/20 zigzag maneuver of the fully appended ONR Tumblehome ship model. Numerical computations are carried out by our in-house CFD code naoe-FOAM-SJTU, which is developed on the open source platform OpenFOAM. The overset grid module is used to predict the ship motions with 20/20 zigzag maneuve...
