Abstract:Fluid machinery is widely used in many fields with clean hydro power turbines producing more than 16% of the total residential electricity consumption and rotating machinery consuming around 30% of the total electrical energy consumption every year. Therefore, the development of advanced, efficient rotating fluid machinery can promote the rapid increase of renewable energy sources such as wind power and photovoltaic power by improving the stability of hydro turbines and pumped storage units over wider operating ranges and increasing the efficiencies of fluid machinery through design optimization and smart controls to support reaching the "double-carbon" targets in China. This paper introduces the challenges and development trends in fluid machinery to develop environmentally friendly, efficient hydropower equipment and safe, stable pumped storage systems through design optimization and smart system controls. This paper also summarizes the recent advances in fluid machinery design to provide guideline for future key fluid machinery development.
