Classical and recent numerical schemes for solving hyperbolic conservation laws were analyzed for computational efficiency and application to nonideal gas flows. The Roe-Pike approximate Riemann solver with entropy correction, the Harten second-order scheme and the extension of the Roe-Pike method to secondorder by the MUSCL strategy were compared for one-dimensional flows of an ideal gas. Thes...

In the present work, we propose a reformulation of the fluxes and interpolation calculations in the PISO method, a well-known pressure-correction solver. This new reformulation introduces the AUSM up flux definition as a replacement for the standard Rhie and Chow method of obtaining fluxes and central interpolation of pressure at the control volume faces. This algorithm tries to compatibilize t...

Pressure driven microscale gas flow-separation has been investigated by solving the compressible Navier-Stokes (NS) system of equations. A two dimensional explicit finite volume (FV) compressible flow solver has been developed using modified advection upwind splitting methods (AUSM+) with no-slip/first order Maxwell’s velocity slip conditions to predict the flowseparation behavior in microdimen...

In this paper we present a new improved design for multi-object auctions and report on the results of tests of that design. We merge the better features of two extant but very different auction processes, the Milgrom FCC design (see Milgrom (1995)) and the Adaptive User Selection Mechanism (AUSM) of Banks et al. (1989)). Then, by adding one crucial new feature, we are able to create a new desig...

Abstract Anomalous convective activity in the Tropics forced by sea surface temperature (SST) variability exerts significant remote influence that provides a basis for seasonal prediction extratropics. In austral summer exhibits pronounced interannual over northern Australia (NAUS), which is, however, unlikely SST anomalies but essentially manifestation of internal Australian monsoon (AUSM) sys...
