... for this task. The highly complex architectures necessary for hybrid propulsion require new methods for design and optimization, for which accurate but computationally fast models are critical. This paper presents a new methodology of using surrogate-based optimization to assist the design of the power system...

... Abstract The present article highlights the implementation of differential evolution (DE)-assisted metaheuristic optimizer to provide the solution of an inverse multi-variable problem related to a flat absorber solar collector consisting of a single glass. For satisfying a given heating...

...-pressure section, hampering the efficiency of the steam turbine. The methodology developed in the subject study aims at counteracting the afore-mentioned effects by optimizing the evaporative cooler air/water ratio which results in the lower possible heat rate for full load and part load operation...

... to need no disruption to production, the utility may be missing out on untapped DR capabilities that could be offered from the ability of the manufacturer to reschedule their production. In either case, the availability of an optimal plan for the manufacturer to best schedule its production in response...

...GAS TURBINE EVAPORATIVE COOLING: A NOVEL METHOD FOR COMBINED CYCLE PLANT PART LOAD OPTIMIZATION Jose Carmona AFRY Zürich, Switzerland ABSTRACT Keywords: Gas turbine, evaporative cooling, combined cycle plant, optimization, part load operation, preheating In power plant engineering, gas turbine (GT...

... 07 01 2011 In modeling and designing micro combined heat and power cycle most important point is recognition of how the cycle operates based on the first and second laws of thermodynamics simultaneously. Analyzing data obtained from thermodynamic analysis employed to optimize MCHP...

... 22 09 2010 Application of two mayor design tools, Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD), for the performance improvement of a 76 MW Francis turbine runner is presented. In order to improve the performance of the runner, not only a CFD based optimization...

... 09 07 2009 The computational fluid dynamic (CFD) based energy improvement of the parametric blade model for a Francis turbine runner is presented. The evaluation of the energy improved uses the results of CFD based optimization of a hydraulic Francis turbine runner. The parametric...

... of the condenser neck structure are the main reasons for the nonuniform velocity distribution of the flow field at the LPES outlet. Furthermore, based on the numerical results, an optimal LPES which has better aerodynamic performance and more reasonable flow is obtained. The optimal structure has low steam...

... to evaluate changes in a precipitator’s configuration and operation to optimize its performance. The author’s applied these techniques to ESPs’ at the Kashira Power Plant near Moscow, having relatively small specific collector area’s (SCA), whose performance will have to be enhanced to meet emerging standards...
