Abstract: The objective of this paper is to assess the techno-economic performance of different cycle configurations for pumped thermal energy storage (PTES), including the effects of charging electricity costs. Reversible turbomachinery ...

Abstract: Due to their high freezing point, molten salt heat exchangers face the problem of salt freezing during cyclic operation. As a result, it is critical to detect the onset of salt solidification and anticipate the phase change ...

Abstract: Two-phase turbines offer the potential to significantly enhance the performance of power generation and refrigeration systems. However, their development has been hindered by comparatively lower efficiencies resulting from ...

Abstract: Meanline models play a crucial role in turbine design and system-level analyses, facilitating rapid evaluation of design concepts and prediction of off-design performance. Most of the existing meanline methods are inadequate ...

Abstract: The implementation of waste heat recovery units on oil and gas offshore platforms demands advances in both design methods and control systems. Modelbased control algorithms can play an important role in the operation of ...
