Abstract: The development of high energy-rate forming machines requires the prediction of the vibrational behavior and noise radiation at the design stage. An automatic optimization technique for minimizing ...

Abstract: This article extends the perturbation method introduced by (2008, “A Novel Method for Analyzing the Global Stability of Inviscid Columnar Swirling Flow in a Finite Pipe,” Phys. Fluids, 20(7), ...

Abstract: Measurements of the resistance to flow through packed beds of inert spheres have been reported by a number of authors through relations expressing the coefficient of drag as a function of ...

Abstract: The establishment of a lunar base with a permanent human presence is on the horizon. The scientific importance of the Moon and the potential use of local resources at a lunar base provide valuable concepts to consider. ...

Abstract: Infrastructure catastrophes, such as the levee failure during Hurricane Katrina and the Fukashima nuclear disaster, are often triggered by a critical combination of events. Typically, engineers evaluate the risk of failure ...

Abstract: A model is proposed for calculating surface reaeration flux for dissolved oxygen (DO) calculations in a river. It is based on a two-film approach, where film thickness is estimated from turbulent length scale and diffusivity ...
