A general framework for the evaluation of shock-capturing schemes

Geometric Shock - Capturing ENO Schemes for SubpixelInterpolation

Subpixel methods that locate curves and their singularities, and that accurately measure geometric quantities, such as orientation and curvature, are of signiicant importance in computer vision and other applications. Such methods often use local surface ts or structural models for a local neighborhood of the curve, to obtain the interpolated curve. Whereas their performance is good in smooth r...

Geometric Shock - Capturing ENO Schemes for SubpixelInterpolation , Computation , and Curve

Subpixel interpolation methods often use local surface ts or structural models in a local neighborhood to obtain the interpolated curve. Whereas their performance is good in smooth regions of the curve, it is typically poor in the vicinity of singularities. Similarly, when geometric estimates are regularized, discontinuities are often blurred over, leading to poor estimates in their vicinity. I...

High-order TVD shock-capturing schemes for unstructured grid solvers

High-order Shock Capturing Schemes for Turbulence Calculations

The goal of this work is to investigate methods for simulating turbulent supersonic flows that include shock waves. Several different types of previously proposed characteristic filters, including total variation diminishing (TVD), monotone upstream-centered scheme for conservation laws (MUSCL), and weighted essentially non-oscillatory (WENO) filters, are investigated in this study. Similar to ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
