Abstract: This paper describes results from a study to evaluate components of an operational air quality modeling system for complex terrain. In particular, the Cinder Cone Butte (CCB) ?modeler's dataset? is used to evaluate the ...

Abstract: Fluid dynamic properties of Dacron vascular grafts were studied under controlled steady-flow conditions over a Reynolds number range of 800 to 4500. Knitted and woven grafts having nominal ...

Abstract: The objective of this paper is to present a grid model for the nonlinear analysis of plates. The model, composed of a grid of beam elements responding in flexure and torsion, is described ...

Abstract: A perturbation expansion and a multigrid technique are developed for simulating the fully-nonlinear unsteady-interaction of short waves riding on long gravity waves. Both numerical techniques are ...

Abstract: Numerical simulations of vortical free-surface flows are prone to developing spurious high-frequency dispersive waves unless the flow field is given sufficient time to adjust. At low Froude ...

Abstract: A simple approach to the estimation of angle variation and losses produced by the secondary flows near the hub and casing of a turbine is presented. The angle variation is predicted by ...

Abstract: Low-frequency turbulent boundary layer eddies inject a power P s into the elastic structure over which the boundary layer is formed which generally greatly exceeds the acoustic power P a ...

Abstract: A simple model for a complex system is presented that contains the essential properties of the guyed tower. The dynamic response to wave load of a guyed tower is represented by a single ...

Abstract: A one-dimensional stress-strain relationship is developed for pure polycrystalline ice subjected to uniaxial compression. The model is based on the continuous damage theories and includes the ...
