The scope of this work is to present and discuss the results obtained from simulating three-dimensional plunging breaking waves by solving the Navier-Stokes equations, in air and water, coupled with a dynamic subgrid scale turbulence model (Large Eddy Simulation, LES). An original numerical tool is used for the complete description of the plunging breaking processes including overturning, splas...

In this paper the high-order accurate spectral difference method for the Navier-Stokes equations is applied to moving boundary problems. Boundary movements are achieved, firstly, through rigid displacement of the entire flow domain. In order to account for the dynamic rigid mesh motion, the Navier-Stokes equations are modified through an unsteady coordinate transformation. Airfoils in pitching ...

In this paper we present, the design and modeling of the novel nonlinear limiter control feedback control plant [Myneni et al., 1999; Corron et al., 2000; Corron & Pethel, 2002], applied for the first time here in an aeroelastic system, and actuated as a jet reaction torquer control of a wing with potentially chaotic dynamics. This study will provide a better understanding of the nonlinear dyna...

J Korean Assoc Oral Maxillofac Surg 2012;38:160-5) Objectives: This study evaluated the clinical results of partial sublingual glandectomy accompanying the excision of ranula as new treatment modality. Materials and Methods: A total of 43 patients who were treated between 1999 and 2007 for oral or plunging ranula were reviewed. All patients were treated surgically by various methods with a tota...

The existence of the radius of marginal stability means that accretion flows around black holes invariably undergo a transition from a MHD turbulent disklike flow to an inward plunging flow. We argue that the plunging inflow can greatly enhance the trapping of large scale magnetic field on the black hole, and therefore may increase the importance of the Blandford-Znajek (BZ) effect relative to ...

The evolution of fault slip through time may yield insight into the geodynamics of deforming lithosphere. Precise determination of temporal variations in fault slip is often hindered, however, by a dearth of markers of varying age from which to reconstruct fault slip. Here we determine slip rates across the White Mountain Fault Zone over the past ca. 0.8 Ma from displaced alluvial deposits pres...

OBJECTIVES/HYPOTHESIS The aim of this study was to evaluate the indications for, and outcomes and limitations of, OK-432 therapy in various otolaryngological cystic diseases. STUDY DESIGN A retrospective clinical study at Yamagata University School of Medicine and the Fukase Clinic in Japan. METHODS Between April 1996 and November 2009 we tried OK-432 therapy in 148 patients with otolaryngo...

At plunging breakers, air bubbles are entrained at the impingement of the water jet, formed at the top of the wave, with the water free surface in front. During the present study, air bubble entrainment at a pseudo-plunging breaker was investigated at near full-scale and further experimental work studied the bubble detrainment process. Experimental observations included the generation and propa...

Part with sculptured surfaces is obtained in three stages: roughing, semi-finishing and finishing. The roughing operation consists in using flat end tools or fillet end tools on sequential horizontal cutting planes to remove the most material from the raw part as rapidly as possible using “Parallel Planes” or “Offset Contours” machining strategy. When roughing deep parts, radial cutting forces,...
