This paper presents an analysis of the noise generated by a marine propeller in oblique flow, using detached eddy simulation for flow field modeling, and Ffowcs Williams Hawkings equation hydroacoustics. The study aims to expand understanding generation from under moderate blade loading subjected lateral which simulates idealized off-design condition like steady-state maneuvering. Hydroacoustic results time frequency domains are compared with those predicted straight conditions, highlighting...
A few months ago, BitTorrent developers announced that the transfer of torrent data in official client was about to switch a new application-layer congestion-control protocol using UDP at transport-layer. This announcement immediately raised an unmotivated buzz new, imminent congestion collapse whole Internet. As control aims offering lower than best effort transport service, this reaction not built on solid technical foundation. Nevertheless, legitimate question remains: whether is...
Abstract. Within the framework of fourth phase International Energy Agency (IEA) Wind Task 29, a large comparison exercise between measurements and aeroelastic simulations has been carried out featuring three simulation cases in axial, sheared yawed inflow conditions. Results were obtained from more than 19 tools originating 12 institutes, ranging fidelity blade element momentum (BEM) to computational fluid dynamics (CFDs) compared state-of-the-art field 2 MW DanAero turbine. More 15...
Abstract This paper presents the activities performed in GARTEUR Action Group HC/AG-26 to study acoustic and aerodynamic characteristics of small rotor configurations, including influence rotor-rotor interactions. will focus on comparisons between numerical wind tunnel results a provided by DLR. The models included Rotor/Rotor/Pylon isolated, tandem coaxial configuration. experiments for acoustics were DLR’s Acoustic Wind Tunnel Braunschweig (AWB) PIV test CIRA within joint CIRA/DLR program....

Last year, the official BitTorrent client switched to LEDBAT, a new congestion control algorithm targeting lower-than Best Effort transport service. In this paper, we study protocol through packet-level simulations, with special focus on performance comparison other protocols such as TCP-LP and TCP-NICE: our aim is indeed quantify relatively weight level of Low-priority provided by protocols. Our results show that LEDBAT generally achieves lowest possible priority, default configurations...
This paper is devoted to a theoretical and numerical hydroacoustic analysis of marine propellers. The use the Ffowcs Williams-Hawkings equation addressed compared with Bernoulli-based methodology, typically used in naval context. A computational tool based on boundary element formulation for velocity potential determine hydrodynamic loads propeller blades. Then, both Bernoulli equations are evaluate pressure far field. role played by incompressibility assumption treated from points view;...
Nowadays, due to excessive queuing, delays on the Internet can grow longer than several round trips between Moon and Earth - for which "bufferbloat" term was recently coined. Some point active queue management (AQM) as solution. Others propose end-to-end low-priority congestion control techniques (LPCC). Under both approaches, promising advances have been made in recent times: notable examples are CoDel AQM, LEDBAT LPCC. In this paper, we warn of a potentially fateful interaction when AQM...
This paper presents a boundary-field integral formulation suitable for the prediction of noise scattered by moving bodies. Although based on same flow modeling assumptions, linear formulations derived from velocity potential or pressure disturbance wave equations provide different predictions when scatterer is not at rest. Indeed, discrepancies reside in influence neglected nonlinear terms. Here, potential-based approach developed extracting first-order contributions yields linearized...
