in this study, effect of slope on soil wetting pattern under surface drip irrigation and simulation with hydrus-2d model evaluated.the physical model made of plexiglas to size 83, 6 and 54 cm (length, width, height) filled with silty clay loam soil was used. to achieve the desired discharge, a small drip irrigation system created that includes a water tank with a fixed height (about 2 meters), ...

Abstract A transient multiphase flow model is established by solving the heterogeneous dynamic equation to simulate process of slag entrapment in tundish, which can provide data for trial production reduce tundish residue on premise ensuring no entrapment. numerical simulation critical height 60 t under different steel throughputs analyzed, and following conclusions are obtained: when throughpu...

[1] To better inform the subsurface scientist on the expected performance of parallel simulators, this work investigates performance of the reactive multiphase flow and multicomponent biogeochemical transport code PFLOTRAN as it is applied to several realistic modeling scenarios run on the Jaguar supercomputer. After a brief introduction to the code's parallel layout and code design, PFLOTRAN's...

Study deals with liquid dispersion of water in unstructured wire mesh rotating packed bed, experimentally investigated using high speed camera. Dispersed outer region bed were captured by high-speed camera and droplet size image processing. Numerical simulations performed on two – dimensional plane similar geometry characteristics (diameter distance between each wire). Volume fluid method was u...

In this article, we propose a novel model to overcome the drawbacks of the modified Chan–Vese (MCV) model. Our model is devoted to find an optimal partition of inhomogeneous regions accurately and computationally efficient. MCV model was proposed on the concept of using one level-set function for one region. It needs fewer numbers of iterations and improves the efficiency of image segmentation ...
