Electrical and optical emission properties of non-equilibrium atmospheric air discharges between a metal pin tap water anode/cathode are presented. With anode the glow type as is derived from short-exposure time plasma imaging electrical characteristics. Additionally, validity extrapolated scaling laws low pressure discharge supports these findings.In case cathode filamentary in nature at surface. In anode, diffuse down to 10 ns. The timescales on which filaments visible near region...
Electrical and optical emission properties of a burning plasma between liquid cathode metal anode are presented in this paper. The has constricted contact points at the is clearly filamentary nature near water surface.The voltage drop depends on conductivity rather than pH significantly different for distilled electrolyte solutions. An acidification due to always observed.The rotational temperature OH N2 bulk is, respectively, range 3200?3750?K 2500?2750?K. nitrogen typically two times...
Stimulated by a recent controversy regarding pressure drops predicted in giant aneurysm with proximal stenosis, the present study sought to assess variability prediction of pressures and flow wide variety research groups. In phase I, lumen geometry, rates, fluid properties were specified, leaving each group choose their solver, discretization, solution strategies. Variability was assessed having interpolate results onto standardized mesh centerline. For II, physical model geometry...
Abstract Model reduction has significant potential in design, optimization and probabilistic analysis applications, but including the parameter dependence reduced‐order model (ROM) remains challenging. In this work, interpolation among matrices is proposed as a means to obtain parameterized ROMs. These ROMs are fast evaluate solve, can be constructed without reference original full‐order model. Spline of system space tangent Riemannian manifold compared with Kriging predicted outputs. A...
Electrical breakdown and water surface deformation in a metal pin–water electrode system with dc applied voltages is studied for small inter-electrode distances (2–12 mm). The radius of curvature the pin 0.5 cm to exclude corona before at these spacings. Calculations as function voltage initial spacing are compared measurements elevation. For smaller than 7 mm calculated stability limit corresponds experimentally obtained voltage. It proved fast CCD images calculations electrical field...
In recent years the role of FSI (fluid-structure interaction) simulations in analysis fluid-mechanics heart valves is becoming more and important, being able to capture interaction between blood both surrounding biological tissues valve itself. When setting up an simulation, several choices have be made select most suitable approach for case interest: particular, simulate flexible leaflet cardiac valves, type discretization fluid domain crucial, which can described with ALE (Arbitrary...
DC-excited discharges in vapour bubbles capillaries are studied. A bubble is generated a capillary filled with NaCl solution due to Joule heating. The fluid columns on either side of the serve as electrodes for electrical inside bubble. breakdown (corresponding corona-to-spark transition) quasi-static discussed. field decreases length. For larger bubbles, reduced smaller than where electron attachment equals ionization, indicating that discharge surface discharge. Linear translation cathode...
Abstract Partitioned fluid–structure interaction simulations of the arterial system are difficult due to incompressibility fluid and shape domain. The interface artificial compressibility (IAC) method mitigates constraint by adding a source term continuity equation in domain adjacent interface. This imitates effect structure's displacement as result pressure disappears when coupling iterations have converged. IAC requires small modification flow solver but not black‐box structural it...
The goal of this paper is to present a computational fluid dynamic (CFD) model with moving boundaries study the intraventricular flows in patient-specific framework. Starting from segmentation real-time transesophageal echocardiographic images, CFD including complete left ventricle and 3D mitral valve was realized. Their motion, known as function time segmented ultrasound imposed boundary condition an Arbitrary Lagrangian-Eulerian framework.The allowed for realistic description displacement...
