International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Synchronized Multiple Drop Impacts into a Deep Pool
Fluids, 2019 Drop impacts (onto dry or wet surfaces or into deep pools) are important in a wide range of applications, and, consequently, many studies, both experimental and numerical, are available in the literature.

Measurement of flow vorticity with helical beams of light
, 2015 It is possible to devise an experiment in which the local vorticity of a flow can be estimated by probing the fluid with Laguerre–Gauss (LG) beams, i.e., optical beams that show an azimuthal phase variation that is the origin of its characteristic ...

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation
Polymer Composites, EarlyView.Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

Joint statistics of acceleration and vorticity in fully developed turbulence
, 2005 We report results from a high resolution numerical study of fluid particles transported by a fully developed turbulent flow. Single particle trajectories were followed for a time range spanning more than three decades, from less than a tenth of the ...

The impact of Arctic sea‐ice loss on winter weather in the British Isles
Quarterly Journal of the Royal Meteorological Society, EarlyView.Arctic sea‐ice loss shifts the North Atlantic jet and storm track equatorward, and results in a more negative North Atlantic Oscillation and more positive East Atlantic and Scandinavian patterns. Strong extratropical cyclones weaken and become less frequent for the British Isles, but there is model disagreement for precipitation, surface winds, and ...

Tip Effect of the Tapping Mode of Atomic Force Microscope in Viscous Fluid Environments
Sensors, 2015 Atomic force microscope with applicable types of operation in a liquid environment is widely used to scan the contours of biological specimens. The contact mode of operation allows a tip to touch a specimen directly but sometimes it damages the specimen;

Stirring Vortices with Vorticity Holes
Procedia IUTAM, 2013 AbstractA vorticity hole is a region with, in absolute value, significantly lower vorticity than its surroundings. Here we discuss the dynamics of a Rankine vortex with two equal circular holes. Since a symmetric initial condition is assumed, the evolution depends on three parameters only: the vorticity drop, the hole radius and the distance between ...

Nuclear vorticity in isoscalar E1 modes: Skyrme-RPA analysis
, 2013 Two basic concepts of nuclear vorticity, hydrodynamical (HD) and Rawenthall-Wambach (RW), are critically inspected. As a test case, we consider the interplay of irrotational and vortical motion in isoscalar electric dipole E1(T=0) modes in $^{208}$Pb ...

Can tropical cyclones exist near the Equator?
Quarterly Journal of the Royal Meteorological Society, EarlyView.Schematic showing how a developed TC responds to reduced Coriolis parameter (f). Zero‐f lowers inertial stability and increases agradient force, enhancing radial inflow at lower levels. Stronger inflow deepens the inflow layer and promotes convergence, intensifying convection and downdrafts in outer rainbands.
