This study investigates the accuracy of different numerical schemes OpenFOAM software to simulate compressible turbulent jets. Both pressure-based utilizing implicit PIMPLE algorithm and density-based relying on AUSM scheme explicit Runge-Kutta time integration are considered. The results tests compared validated against data from NASA ARN nozzle geometry. choice parameter setting is discussed ...

This paper studies the uniqueness of two non-integral finite ordered meromorphic functions with finitely many poles when they share sets. Also, it provides an answer to a question posed by Gross for particular class functions. Moreover, some observations are made on results due Sahoo and Karmakar, Acta Univ. Sapient. Math., doi:10.2478/ausm-2018-0025; Sarkar, Bol. Soc. Mat. Mex., doi:10.1007/s4...

The paper describes the implementation details and validation results for an agglomeration multigrid procedure developed in the context of hybrid, unstructured grid solutions of aerodynamic flows. The governing equations are discretized using an unstructured grid finite volume method, which is capable of handling hybrid unstructured grids. A centered scheme as well as a second order version of ...

I this paper we present a new improved design for multiobject auctions and report on the results of experimental tests of that design. We merge the better features of two extant but very different auction processes, the Simultaneous Multiple Round (SMR) design used by the FCC to auction the electromagnetic spectrum and the Adaptive User Selection Mechanism (AUSM) of Banks et al. (1989, “Allocat...

The design of the thermal protection system requires high-precision and high-reliability CFD simulation for validation. To accurately predict hypersonic aerodynamic heating, an overall strategy based on mutual selection is proposed. Foremost, grid criterion wall cell Reynolds number developed. Subsequently, dependence turbulence model discretization scheme considered. It suggested that appropri...
