Aim of this article is to introduce and present advantages possibilities using simulation tools calculate energy flows tractive vehicle in all phases its ride. The focus on the braking phase, especially recuperation that offers highest saving potential.Energetic was carried out as a part current railway reconstruction study, which good example possible energetic calculation use. Energetic are p...

retrofit of heat exchanger networks for energy saving and/or debottlenecking is one of important aspects of process engineering. pinch technology, as the most efficient tool for the analysis of these networks, has been applied to hundreds of such projects and shown satisfactory results. however, all the existing methods for debottlenecking, using pinch technology, are either based on assumed he...
