the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولLarge-Eddy Simulation of Turbulent Combustion
In recent years, Large Eddy Simulation (LES) has been successfully applied to non-premixed and premixed turbulent combustion problems [1, 2, 3]. In most technical combustion applications, the pure non-premixed or premixed combustion models are no longer valid, since partially premixed combustion has to be taken into account. An example is the stabilization region of a lifted non-premixed flame....
متن کاملA ‘Synthetic Scalar’ Subgrid-Scale Model for Large-Eddy Simulation of Turbulent Combustion
In this paper we present an alternative formalism for large-eddy simulation that avoids the problems arising from filtering the governing equations. In particular, we instead propose to filter solutions leading to the ability to directly model subgrid-scale primitive variables; i.e., model physics rather than statistics. We then demonstrate construction of subgrid-scale models of scalar quantit...
متن کاملEulerian transported probability density function sub-filter model for large-eddy simulations of turbulent combustion
Reactive flow simulations using large-eddy simulations (LES) require modelling of sub-filter fluctuations. Although conserved scalars like mixture fraction can be represented using a beta-function, the reactive scalar probability density function (PDF) does not follow an universal shape. A one-point one-time joint composition PDF transport equation can be used to describe the evolution of the s...
متن کاملPrediction of combustion-generated noise in non-premixed turbulent flames using large-eddy simulation
Noise generated from technical devices is an increasingly important problem. Jet engines in particular produce sound levels that are not only a nuisance, but may also impair hearing. The noise emitted by such engines is generated by different sources, such as jet exhaust, fans or turbines, and combustion. Increasing restrictions on the allowable noise-emission levels force manufacturers to desi...
