Hydraulic machinery has been widely used in production work and civilization construction since ancient times. Early hydraulic machinery such as the waterwheel used by the ancients and the Archimedes' screw, which is regarded as one of the great inventions that changed the world. By now, hydraulic turbines are widely used in small to large hydropower plants, providing the most stable and efficient clean energy of the contemporary era; pumps are widely utilized in water conservancy projects, industrial processes and many other fields; pump-turbines are applied in pumped storage power plants, which are the most effective large-scale energy storage equipment in the context of the world's carbon peak and carbon neutrality. Generally, the steady and unsteady performance of hydraulic machinery is the external expression of internal flow field evolution, which will lead to changes of mechanical property for the hydraulic machinery.
While hydraulic machinery is now widely explored, the investigation of its internal flow state has become an indispensable and important aspect affecting the efficiency and stability of hydraulic machinery and its systems. Nowadays, more and more research uses various advanced means and technologies to explore the core mechanism of the internal flow of hydraulic machinery from multiple angles, to improve the energy performance and safety of its equipment, the stability, reliability and flexibility of its operation, and thus further enhance the safe and stable operation level of engineering practices as well as the technical and economic level. Therefore, it is of great significance to collect the most recent information on this topic.
The current Research Topic aims to present the most recent advancement and novel research trends focused on the investigation of the internal flow mechanism of modern hydraulic machinery. We are pleased to welcome submissions of all article types with an emphasis on Original Research, Opinion and Review articles of the following topics (but not limited to):
1. Design and optimization of hydraulic machinery
2. Unsteady flow characteristics of hydraulic machinery
3. Transient process of hydraulic machinery
4. Cavitation and erosion of hydraulic machinery
5. Numerical methods for hydraulic machinery
6. Hydraulic Machinery used in tidal and wave energy
7. New concepts of hydraulic machinery
