The purpose of this study is to model the flow movement in an idealized dam-break configuration. One-dimensional and two-dimensional motion of a shallow flow over a rigid inclined bed is considered. The resulting shallow water equations are solved by finite volumes using the Roe and HLL schemes. At first, the one-dimensional model is considered in the development process. With conservative fini...

In this paper we present Gun3P, a parallel 3D finite element application that the Advanced Computations Department at the Stanford Linear Accelerator Center is developing for the analysis of beam formation in DC guns and beam transport in klystrons. Gun3P is targeted specially to complex geometries that cannot be described by 2D models and cannot be easily handled by finite difference discretiz...

The temperature inversion symmetry, for a non interacting super-symmetric ensemble, at finite volume, is studied. It is found that, the scaled free energy, f (ξ), is antisymmetric under temperature inversion transformation, i.e. f (ξ) = −ξ d f (1 ξ). This occurs for antiperiodic bosons and periodic fermions, in the compact dimension. On the contrary , for periodic bosons and antiperiodic fermio...

Teaching students how to think critically and develop lifelong habits of evidence-based inquiry outside of the classroom is a primary goal for educators today. This paper describes nine activities designed to promote evidence-based critical thinking in college or high school classrooms in any discipline. We have developed a seven step process for critical thinking, with teaching modules designe...

In this study, an analysis has been performed for free convection with radiation effect over a thermal forming nonlinearly stretching sheet. Parameters n, k0, Pr, G represent the dominance of the nonlinearly effect, radiation effect, heat transfer and free convection effects which have been presented in governing equations, respectively. The similarity transformation and the finite-difference m...
