A millimeter wave technique for measuring ice thickness on the Space Shuttle's external tank
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
The external fueltank of the Space Shuttle contains extremely lowtemperature propellents. A layer of material known as SOFI (Spray-On Foam Insulation) covering the outside of the fueltank provides thermal insulation between ...
Buoyancy-driven turbulent diffusion flames
(Elsevier, 1991-08)
A fundamental dimensionless number for pool fires, , in proposed. Here [sigma][beta] and Ra[beta] denote a flame Schmidt number and a flame Rayleigh number. The sublayer thickness of a turbulent pool fire, [eta][beta], is ...
Theory of lateral bandgap variation achievable by strain engineering in patterned substrate strain epitaxy
(Elsevier, 1990)
Energy minimization considerations are used to estimate the strain tensor for pseudomorphic structures grown on a patterned substrate. We show that if a material B is deposited below critical thickness in a hole of width ...
Spark ignition of propane-air mixtures near the minimum ignition energy: Part II. A model development
(Elsevier, 1991-01)
A model is developed to simulate the kernel growth observed in the exprimental study of Part I. Kernel growth, described as a two-step process, initially involves a blast wave over a negligible short time followed by a ...
Infinite Prandtl Number Convection
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic/Plenum Publishers ; Springer Science+Business Media, 1999-01)
We prove an inequality of the type N ≤ CR 1/3 (1+log + R ) 2/3 for the Nusselt number N in terms of the Rayleigh number R for the equations describing three-dimensional Rayleigh–Bénard convection in the limit of infinite ...
Stability of coextrusion through converging dies
(Elsevier, 1991-12)
A linear stability analysis of multilayer flow of viscoelastic liquids through long, converging dies is performed by a rigorous two-dimensional analysis (2-D), as well as by a simplified one-dimensional analysis (1-D) on ...
Renormalization scheme dependence in e+e- annihilation and [tau]-lepton decay at the next-to-next-to-leading order of perturbative QCD
(Elsevier, 1991-09-12)
We present a detailed investigation of the renormalization scheme dependence of the next-to-next-to-leading order QCD predictions for the processes e+e--->hadrons and [tau]-->[nu][tau]+hadrons. Based on it the ...
Nearest-neighbor distances in diffusion-controlled reactions modelled by a single mobile trap
(Elsevier, 1991-02-15)
We consider a system consisting of an infinite number of identical particles on a lattice initially uniformly distributed, which diffuese in the presence of a singke mobile trap and ask for the time-dependent behavior of ...
Evidence for multiple scattering of high energy partons in nuclei
(Elsevier, 1991-04-18)
New experimental information is presented about the effect of a nucleus on partons which have undergone a hard scatter. We have observed clear dijet events from 400 GeV / c p-nucleus interactions and compared them to dijets ...
Erratum: Quasi-collinear and partially degenerate four-wave mixing: An alternative explanation of the phase-conjugation property of backward stimulated scattering [JETP 88, 235–245 (February 1999)]
(Nauka/Interperiodica; American Institute of Physics ; Springer Science+Business Media, 1999-06)
