Title: Interphase Momentum and Heat Exchange in Turbulent Dust-Laden Plasma Jet under Continuous Radial Powder Injection

Abstract

Potential possibilities of an advanced approach based on the usage of DC cascade torch providing an axially symmetric plasma jet outflow, and continuous radial injection of powder into a plasma flow are discussed. Comparison is made of the results, obtained using two models of interphase heat and momentum exchange between polydisperse alumina particles and air plasma jet, other factors being the same. The widely used model of gradientless particles' heating was applied for computing the two-phase plasma jets' temperature and velocity fields. The model is compared with corresponding model of gradient particle heating computed by using an efficient numerical method developed. Calculations were conducted under different scales of dense loading conditions to estimate the maximum productivity of plasma spray process.

  • The convincing evidence of Verma et al. that K/sub H/ does not equal K/sub W/ in conditions when H and LE are of opposite sign is not necessarily in conflict with the predictions of conventional flux-gradient relations, particularly when the gradient measurements are made very close to the canopy. Almost all the extensive flux-gradient investigations of the past 20 years have been conducted over relatively short, often sparse, vegetation. Before formulations derived from such circumstances can be extended to the case of deeper canopies, it must be assured that the zero-plane displacement heights are known to sufficient accuracy. Citing othermore » studies the authors state that the suggestion that different zero planes might be appropriate to the cases of temperature and humidity profiles is fairly clear. The heights of observations listed in the data of Verma indicate that in their particular experiment zero-plane displacement inequalities might explain part of the observed differences between K/sub H/ and K/sub W/. On analysis of Verma's data for k/sub H//K/sub W/, the authors conclude that part of the observed difference between K/sub H/ and K/sub W/ might have been done to this effect. The authors also point out that attempts to relate K/sub H//K/sub W/ to ..delta..T/..delta..e and LE/(R/sub n/ + S) are likely to be quite misleading. To illustrate this point, a surrogate data set was constructed from random numbers to provide values simulating ..delta..T/..delta..e ranging from -0.15 to -0.85 and uncorrelated values of LE/(R/sub n/ + S) ranging from -1.2 to -2.4. The data were treated in the same manner used by Verma. These values are then compared to those reported by Verman et al.« less
  • The propagation pattern of electromagnetic waves (EMWs) in dusty plasmas is quite different from that in electron-ion plasmas. For instance, here the ponderomotive force acts on dust grains as a negative pressure, and a nonlinear Schroedinger equation with an additional nonlinear term is obtained. Based on this equation, the modulation instability is examined and it is shown that the growth rate becomes maximum when that additional term compensates the diffraction term. The main part of this work is devoted to the localization of the grains by the EMW. Considering both subsonic and supersonic regimes, it has been shown that undermore » certain conditions the grains are localized and the ions circumnavigate the grains, whereas the electrons escape from the region of localization. Further, the localization of grains by the EMW is found to be shape-dependent of the pulse. Comparing pancake and light bullet shaped pulses in the supersonic regime, and it is shown that only the light bullet shape leads to the compression of grains. Finally, investigating nonstationary solution, it is shown that for some parameters, the nonlinear wave breaking and the formation of a shock wave can take place.« less
  • Thermal plasma processing involves complex interactions of particulates with plasmas. In previous studies (see Parts I and II of this series), an assessment of different effects has been made considering the dynamics and heat and mass transfer of a single particle immersed into a thermal plasma. The last paper of this sequence is concerned with the simulation of thermal plasma jet reactors and the effects caused by multiparticle injection. A mathematical model is proposed for the simulation of thermal plasma jet reactors, including the mixing phenomena between the jet and the surrounding gases by generalizing the governing equations for simplemore » mixing flows. Also included is the density fluctuation effect by extending the K-epsilon model to a four-equation turbulence model combined with a probability density function. This model is internally consistent covering additional physical phenomena which are not covered by existing models. Unfortunately, its expected higher accuracy cannot be proven because of the present uncertainties associated with the input. For multiparticle injection, the simulation repeats calculations for single-particle injection, bit with different initial conditions correcting the solutions by considering the coupling effects between particles and the plasma. The results indicate that (i) thermal plasmas show different mixing behavior in different gases; (ii) the density fluctuation effect is important since it causes large differences between the mass-weighted and unweighted time-averaged temperatures of thermal plasma jets; (iii) coupling effects become important when the particle loading rate exceeds half of the plasma mass flow rate; (iv) there are 16 constraints imposed on the modeling work which have to be considered for establishing a base for comparison with future experimental studies.« less
  • Stress fields in a continuous fiber composite with a variable interphase subjected to thermomechanical loadings are studied by using a four concentric circular cylinders model. An exact closed form solution is obtained for the stress field in the interphase in a series form using Frobenius method in a certain case. Numerical results are presented for FP fiber/Al 6061 composite with interphase, and carbon fiber/Al 6061 composite with interphase. It is found that the variableness of the thermoelastic constants in the interphase has significant effects on the stress distributions in the interphase. Therefore, this will, in turn, affect the initiation ofmore » cracks in the interphase.« less
  • Momentum and heat transfer associated with a translating liquid droplet with/without mass efflux from the droplet surface in a quiescent argon thermal plasma environment is studied. A Chebyshev--Legendre spectral method with a fractional time stepping method is expanded to treat the compressible nature of the thermal plasma flow as well as the internal droplet incompressible flow. Steady-state solutions for the case of plasma flow over a constant temperature solid sphere and incompressible flow over a droplet without mass efflux from the droplet are calculated and compared with previously published results. The interfacial phenomena are studied with interfacial physical properties. Transientmore » solutions with droplet internal motion and convective heat transfer with/without mass efflux from the sphere surface are presented. Results indicate that uniform droplet internal temperature is established more quickly than that of a solid sphere in the plasma environment for no mass efflux case. Also, a symmetric interfacial velocity distribution develops along the droplet interface as Reynolds number increases. In case of mass efflux from the sphere, results show that the drag force and heat transfer rate are reduced in the presence of radial mass efflux at the droplet surface.« less
