Abstract Reckless discharge of industrial wastewater and domestic sewage as well frequent leakage crude oil have caused serious environmental problems posed severe threat to human survival. Various nature inspired superhy-drophobic surfaces been successfully applied in oily water remediation. However, further improvements are still urgently needed for practical application terms facile synthesi...

In this paper, an adaptive physics-based method is developed for solving wave motion problems in one dimension (i.e., wave propagation in strings, rods and beams). The solution of the problem includes two main parts. In the first part, after discretization of the domain, a physics-based method is developed considering the conservation of mass and the balance of momentum. In the second part, ada...

Model-based advanced process control strategies are common applications in the hydrocarbon processing industry. A close look at the references available in literature reveals that the overwhelming majority of these projects are concentrated in refineries and in some specific petrochemical plants (e.g., ethylene). This is due to the excellent economic returns demonstrated in an abundance of expe...

Mesh partitioning is often the preferred approach for solving unstructured computational mechanics problems on massively parallel processors. Research in this area has focused so far on the automatic generation of subdomains with minimum interface points. In this paper, we address this issue and emphasize other aspects of the partitioning problem including the fast generation of large-scale mes...

Recently, advanced visualizing techniques in computer graphics have considerably enhanced the visual appearance of synthetic models. To realize enhanced visual graphics for synthetic medical effects, the first step followed by rendering techniques involves attaching albedo textures to the region where a certain graphic is to be rendered. For instance, in order to render wound textures efficient...

A good mesh is a prerequisite for achieving reliable results from Computational Fluid Dynamics (CFD) calculations. Mesh properties include types, computational domain sizes, and node distributions. However, in literature, we found no clear consensus about what these should be. In this article, performed case study on ship rudders to determine the suitable are airfoil-shaped profiles. classic NA...

This paper presents a novel progressive mesh model based on collapse tree, which can accomplish the disordered expansions and collapses of the simplified mesh and is able to restore the mesh just in a specific area. With arbitrary collapse and expansion, we design an edge collapse algorithm for mesh optimization. Its summary process can be described as follows: generating a series of new simpli...

A discrete geometry can have artifacts such as holes, intersections, nonmanifold edges, mesh fragment among other defects depending upon its origin. These kinds of defects sometime cause the geometry to be unsuitable for any further use in computational simulation in absence of a satisfactory geometry repair technique. There are two main approaches to geometry repair, surface based and volume b...
