Two-phase flows in gun barrel: Theoretical and experimental studies
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
In the paper theoretical and numerical model of two-phase flow of solid granular propellant and its products of combustion in the gun barrel during interior ballistic cycle is given. Two cases are considered: base ignition ...
Experimental method for determining Forchheimer equation coefficients related to flow of air through the bales of soy straw
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The paper presents results of experimental investigation conducted to determine permeability coefficient of a porous bed formed by biomass bales, whereby the said coefficient represents one of the most important parameters ...
Fade performance prediction of automotive friction materials by means of artificial neural networks
(Elsevier Science Sa, Lausanne, 2007)
Temperature sensitivity of friction materials has always been a critical aspect while ensuring their smooth and reliable functioning, and that sensitivity need to be constantly optimized. The performance of friction materials ...
Redundancy problem in writing: From human to anthropomorphic robot arm
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 1998)
This paper presents the analysis of motion of a redundant anthropomorphic arm during the writing. The modeling is based on the separation of the prescribed movement into two motions: smooth global, and fast local motion, ...
Nonlinear transformation of electromagnetic waves in suddenly created cold magnetized plasma: Longitudinal propagation
(AIP Publishing, MELVILLE, 2002)
The transformation of a circularly polarized electromagnetic source wave in a suddenly created cold magnetized and weakly nonlinear plasma is considered. For the case of longitudinal propagation (a source wave propagating ...
Electron drift velocities in mixtures of helium and xenon and experimental verification of corrections to Blanc's law
(Amer Physical Soc, College Pk, 2005)
Measurements of electron drift velocities were performed in pure Xe and He and in a number of mixtures ranging up to 70% of Xe. The data were obtained by using a pulsed Townsend technique over the density-normalized electric ...
Advanced seismic slope stability analysis
(Springer Verlag, 2013)
The objective of this study was to present an advanced methodology for assessing seismic slope stability by taking into account the uncertainties related to the main input parameters. The methodology was applied on a real ...
Research on the shell-side thermal performances of heat exchangers with helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper presents the results of experimental research on shell-side heat transfer coefficient concerning 3 heat exchangers with helical coils. Measurements were carried in laboratory and the following correlation was ...
Low-temperature convective drying of apple cubes
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The paper presents results of an experimental investigation of convective drying of Idared apple in full recirculation laboratory scale dryer. The experiments were conducted with cube-shaped apple samples (side length 10 ...
