| This research work allocates to physical models in order to simulate real world results of the steam hammer at turbine multi-series pipeline in power plants. The aim of this study is to investigate the effect of a steam hammer on a steam turbine line and calculation the force on the shock absorber at the end of the main pipeline. For this purpose, the new theoretical model based on thermodynamic relationships and accurate calculation of wave speed propagation was developed and implemented into the physical model. The main achievement of this research is to present a simple and accurate theoretical model that can provide a bridge between hydro-mechanical data and estimates the impact force of the steam hammer on piping with less computational effort than finite element and a less costly setup than experimental models. The method of characteristics as a complement to the theoretical model was applied and compared. In this work, special attention is devoted to the study of the most relevant process parameters, with emphasis on their meaning, effects, and mutual interaction. The present paper organizes a theoretical model and numerical method of characteristics to predict steam hammer transients behavior in a multi-series pipeline. The initial results are promising and indicate the possibility of using the proposed simple yet, but efficient theoretical model than finite element models in terms of quality, cost, and time consumption of producing results. | ||
