Abstract

Steady-state planar ablative flow in a laser produced plasma is studied. The calculations relate all steady-state fluid quantities to only three parameters, the material, absorbed irradiance, and laser wavelength. Here, the fluid is divided into three regions; the subcritical expanding plasma, the steady-state ablation front, and the accelerated slab. Boundary conditions at the interfaces of these regions are given. If the absorbed irradiance is nonuniform, the nonuniformity in ablation pressure is calculated. Results are compared with experiment and fluid simulation for both uniform and nonuniform illumination.

Fractal dimension of cohesive sediment flocs at steady state under seven shear flow conditions

Journal Article Zhu, Zhongfan ; Yu, Jingshan ; Wang, Hongrui ; ... - Water (Basel)

The morphological properties of kaolin flocs were investigated in a Couette-flow experiment at the steady state under seven shear flow conditions (shear rates of 5.36, 9.17, 14, 24, 31, 41 and 53 s ^-1). These properties include a one-dimensional (1-D) fractal dimension (D ₁), a two-dimensional (2-D) fractal dimension (D ₂), a perimeter-based fractal dimension (D _pf) and an aspect ratio (AR). They were calculated based on the projected area (A), equivalent size, perimeter (P) and length (L) of the major axis of the floc determined through sample observation and an image analysis system. The parameter D ₂, which characterizesmore »« less

Plasma flow reactor for steady state monitoring of physical and chemical processes at high temperatures

Journal Article Koroglu, Batikan ; Mehl, Marco ; Armstrong, Michael R. ; ... - Review of Scientific Instruments

Here, we present the development of a steady state plasma flow reactor to investigate gas phase physical and chemical processes that occur at high temperature (1000 < T < 5000 K) and atmospheric pressure. The reactor consists of a glass tube that is attached to an inductively coupled argon plasma generator via an adaptor (ring flow injector). We have modeled the system using computational fluid dynamics simulations that are bounded by measured temperatures. In situ line-of-sight optical emission and absorption spectroscopy have been used to determine the structures and concentrations of molecules formed during rapid cooling of reactants after theymore »« less

Newton-Krylov method in solving drift-flux two-phase flow problems for both pre-CHF and post-CHF conditions at steady state

Journal Article Zou, Ling ; Zhao, Haihua ; Zhang, Hongbin - Annals of Nuclear Energy (Oxford)

Furthermore, this paper presents numerical simulations of two-phase flow heat transfer for both pre-CHF and post-CHF conditions typical in light water nuclear reactors. The conjugate heat transfer problem is modeled with one-dimensional drift-flux two-phase flow model for coolant flow and two-dimensional heat conduction equation in solid walls. Fully implicit time integration schemes were employed, and the resulted non-linear equations were solved with a Newton-Krylov method. For the drift-flux two-phase flow model, the EPRI drift-flux closure correlation is used to model the relative motion between the two phases. Additional closure correlations were adopted from REALP5-3D to determine two-phase flow regime, wallmore »« less

Steady-state planar ablative flow

Technical Report Manheimer, W.M. ; Colombant, D.G. ; Gardner, J.H.

This paper discusses the theory of ablative acceleration. Since this problem can be solved in either one or two dimensions by fluid simulation, our principal object is not to find detailed solutions which can be compared precisely with experiment. Rather it is to shed light on the physics of ablative acceleration and to derive simple scaling laws. We do derive simple scaling laws for ablation pressure, blow-off velocity and separation between critical and ablation surfaces. These scaling laws depend only on the material, laser wavelength and absorbed laser irradiance. The key to deriving these simple scaling laws is not reallymore »« less
