heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
A flow visualization study was carried out for boiling in a rectangular channel filled with and without metallic random porous media. Four main patterns are observed as intermittent slug-churn flow, churn-annular annular-mist mist regimes. These clearly classified based on the high-speed images of flow. The results pattern map according to mass rate were presented using saturation temperatures ...
the objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. the deform-3d software was used by incorporating a lagrangian incremental formulation. threedimensional results of the material flow pattern which were extracted using the point...
