Variability of Winter Storminess in the Eastern United States during the Twentieth Century from Tide Gauges

Interannual to multidecadal variability of winter storminess in the eastern United States was studied using water level measurements from coastal tide gauges. The proximity to the coast of the primary winter storm track in the region allows the use of tide ...

Dynamic stall development

Karen Ann J Mulleners

Dynamic stall on an oscillating airfoil was investigated by a combination of surface pressure measurements and time-resolved particle image velocimetry. Following up on previous work on the onset of dynamic stall (Mulleners and Raffel in Exp Fluids 52(3):7 ...

One- and two-dimensional UVP velocity sampling in a cuboidal basin subject to in- and outflow sequences

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of an experimental study on the influence of in- and outflow sequences on flow patterns and suspended sediment behavior in reservoirs, flow fields and inflowing jet were sampled by Ultrasonic Velocity Profilers (UVP). The laboratory set-up ...

Short wavelength ion temperature gradient turbulence

Laurent Villard, Stephan Brunner, Xavier Lapillonne

The ion temperature gradient (ITG) mode in the high wavenumber regime (k(y)rho(s) > 1), referred to as short wavelength ion temperature gradient mode (SWITG) is studied using the nonlinear gyrokinetic electromagnetic code GENE. It is shown that, although t ...

Quantification of the Small-Scale Spatial Structure of the Raindrop Size Distribution from a Network of Disdrometers

Alexis Berne, Joël Jaffrain

The spatial structure of the raindrop size distribution (DSD) conveys crucial information for reliable quantitative estimation of rainfall using remote sensing techniques. To investigate this question, a network of 16 optical disdrometers has been deployed ...

Synergy between ion temperature gradient turbulence and neoclassical processes in global gyrokinetic particle-in-cell simulations

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

Based on the CYCLONE case, simulations of collisional electrostatic ion temperature gradient (ITG) microturbulence carried out with the global gyrokinetic particle-in-cell (PIC) code ORB5 are presented. Considering adiabatic electrons, an increase in ion h ...

Sensitivity studies of dust ice nuclei effect on cirrus clouds with the community atmosphere model CAM5

Athanasios Nenes

In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations. Both parameterizations consider ...

Swirl Jets in Crossflow at Low Velocity Ratios

Peter Ott, Alexandros Terzis, Charilaos Kazakos

This investigation examines experimentally the behavior of swirled jets produced by axial flow fans blowing into a crossflow at low velocity ratios. The main difference with non-swirl cases is an asymmetry of the dominant kidney vortex and a slight distort ...

Effect of pre-aerated approach flow on delector-generated jets

Michael Pfister

Flip buckets are terminal spillway elements, generating free jets for energy dissipation. Deflectors are an alternative to flip buckets with constructional ease yet of similar hydraulic features. A first experimental study published at the 33rd IAHR Congre ...

Effects of Swirl Velocities From Fan Assemblies Mounted on Lifting Surfaces

Alexandros Terzis, Charilaos Kazakos, Nikolaos Papadopoulos

The penetration of a jet of fluid into a traversal moving stream is a basic configuration of a wide range of engineering applications, such as film cooling and V/STOL aircrafts. This investigation examines experimentally the effect of blowing ratio of fans ...
