Abstract: A study of infiltration-type air flows through a room-size enclosure with an obstructing wall was conducted. A finite volume (cell finite difference) method was used, and a k-ε turbulence model ...

Abstract: The feasibility of using a new characteristic dimension (equivalent diameter) is explored for predicting rarefied flows in noncircular tubes. A conclusion is that a single characteristic dimension ...

Abstract: This paper offers importance vectors to identify the structural parameters that are most cost efficient to change to improve the reliability of an underperforming design. The methodology comprises the synthesis of reliability ...

Abstract: A generalized approach based on a model of the Boltzmann equation is suggested for predicting velocity profiles and gas flow rates through trapezoidal microgaps. Sample results are given for ...

Abstract: An experimental investigation of the mechanics of hydrodynamic lubrication and heat generation and dissipation of packed-gland rotary shaft seals was performed on a somewhat novel design. The ...

Abstract: In this paper, an innovative modeling approach is presented for the simulation of underground construction with the emphasis on tunneling. The boundary element method (BEM) is used, and the theoretical background is discussed ...

Abstract: Data collected during the Surface Waves and Processes Program are employed to investigate a possible interrelation between wind stress and surface wave breaking. From comparison of data from 15 half-hour long time segments, ...

Abstract: adiative and dynamical heating rates control stratospheric temperatures. In this study, radiative temperature trends due to ozone depletion and increasing well-mixed greenhouse gases from 1980 to 2000 in the polar stratosphere ...
