Abstract: Abstract. Partial-evaporation organic Rankine cycle power systems are a promising technology for power generation from low-temperature heat sources such as waste heat and geothermal heat. A specific challenge in two-phase ...

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: Abstract. Meanline modeling is vital in turbomachinery design process, enabling accurate and computationally efficient performance analysis and design optimization. In gradient-based optimization, accurate derivatives are ...

Abstract: Abstract. Meanline modeling provides an effective tool for preliminary turbomachinery design, yet its integration with black-box optimization frameworks is often hindered by high computational costs and potential convergence ...

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: Abstract. Two-phase axial turbines offer a promising solution for improving the efficiency of energy conversion systems such as partial-evaporation organic Rankine cycles power systems, and refrigeration processes. However, ...

Abstract: Currently, most of the adjoint-based design systems documented in the open literature assume that the fluid behaves as an ideal gas, are restricted to the optimization of a single row of blades, or are not suited to impose ...
