Abstract. This paper presents the multiscale analysis and numerical algorithms for the convectiondiffusion equations with rapidly oscillating periodic discontinuous coefficients. The multiscale asymptotic expansions are developed and an explicit rate of convergence is derived for the convex domains. An efficient multiscale hybrid FEM-FVM algorithm is constructed, and numerical experiments are r...

The understanding of flow problems, and finding their solution, has been important for most of human history, from the design of aqueducts to boats and airplanes. The use of physical miniature models and wind tunnels were, and still are, useful tools for design, but with the development of computers, an increasingly large part of the design process is assisted by computational fluid dynamics (C...

The density and viscosity of propane mixed with 66/34 trans/cis-decahydronaphthalene were measured over a wide range of temperatures (323 – 423K), pressures (2.5-208 bar), and compositions (0-65 mol% propane). For conditions giving two phases, the composition of the dense phase was measured in addition to the density and viscosity. The modified SanchezLacombe equation of state (MSLEOS) was used...

Successful adoption and implementation of ERP Systems has been the subject of extensive research as can be evidenced by the large body of research literature on this topic. However, the effect of cross-cultural issues has been less widely studied, perhaps because of the difficulty and complexity of such cross-cultural studies. In today’s global business environment this remains a key issue and ...

Here, recent developments in the key numerical approaches to water hammer modelling are summarized and critiqued. This paper summarizes one-dimensional using finite difference method (FDM), of characteristics (MOC), especially more volume (FVM). The discussion is briefly extended two-dimensional modelling, as well computational fluid dynamics (CFD) approaches. Finite methods particular note, si...
