A guided artificial bee colony (GABC) heuristic for permutation flowshop scheduling problem (PFSP) [PDF]

open access: yes, 2021
Flowshop is the most common production system in the industry, and there are many documented efforts to improve the performance of the flowshop. The range spreads from the usage of heuristics to metaheuristics, and one of the promising methods is NEH (

Evaluating the sensitivity of surrogate optimization target properties characterizing droplet formation, evaporation, and chemical reactions to biodiesel composition reduction

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Liquid fuels contain a large number of components. However, it is not computationally feasible to implement the detailed composition into numerical solvers in combustion chamber design. Surrogate mixtures are used to facilitate calculations, which can reproduce the fuel characteristics with fewer components providing reasonable accuracy ...

Parametric Study on the Performance of Gas Springs in FPSE With Pneumatic Supporting System

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The introduction of a pneumatic supporting system composed of gas springs and hydrostatic bearings in the free‐piston Stirling generator (FPSG) can effectively increase the power density of the nuclear space power plant. In this paper, a 1 kW FPSG with pneumatic supporting system was developed, and the working characteristics of dual gas ...

Relationship between Nusselt and Rayleigh Numbers in Natural Convection

open access: yesThe Eurasia Proceedings of Science Technology Engineering and Mathematics, 2023
When studying heat transfer in laminar or turbulent flow, the aim is to maximize heat transfer, using for example corrugated channels; nanofluids or hybrid nanofluids, etc.; to determine the factors that influence the thermal and hydraulic performance of the used equipment and to determine the relationships that may exist between heat transfer ...
