Pumped storage technology is a large-scale, efficient, flexible and clean energy storage technology. The core of it is the design of pumped storage units, which involves the operation and flow characteristics of vane hydraulic machinery under pump and turbine modes, as well as the complex flow conditions of the upstream and downstream flow channels of the units. With this as the background, this book expounds on the relevant problems and their solutions, providing a scientific basis for the development of pumped storage technology. I hope this book can provide as a useful reference for readers.

The use of composite materials in the design process allows one to tailer a component’s mechanical properties, thus reducing its overall weight. On the one hand, the possible combinations of matrices, reinforcements, and technologies provides more options to the designer. On the other hand, it increases the fields that need to be investigated in order to obtain all the information requested for a safe design. This Applied Sciences Special Issue, “Composite Materials in Design Processes”, collects recent advances in the design methods for components made of composites and composite material properties at a laminate level or using a multi-scale approach.

This book focuses on some fundamental issues of polymers’ natural degradation. It is mostly devoted to the different aspects of biodegradation, but some data on the action of water, oxygen, ozone, and UV/Vis light is also included. The consideration of the biodegradation in vivo as the superposition of decay and synthesis provides the opportunity for a fresh look at well-known processes.

Wood composites have shown very good performance and substantial service lives when correctly specified for the exposure risks present. The selection of an appropriate product for the job should be accompanied by decisions about the appropriate protection, whether this is by design, by preservative treatment, or by wood modification techniques. This Special Issue, “Advances in Wood Composites II”, presents recent progress in enhancing and refining the performance and properties of wood composites by chemical and thermal modification and the application of smart nanomaterials. Such enhancements and refinements have made wood composites a particular area of interest for researchers. In addition, this Special Issue reviews some important aspects in the field of wood composites, with particular focus on their materials, applications, and engineering and scientific advances, including solutions inspired biomimetically by the structure of wood and wood composites. This Special Issue, as a collection of 14 original contributions, provides selected examples of recent advances in wood composites.

Fluid interfaces are promising candidates for confining different types of materials - e.g., polymers, surfactants, colloids, and even small molecules - and for designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the Physico-chemical bases underlying the formation of layers at fluid interfaces, as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and dynamics features in the interfacial systems, which are far from those conventionally found in the traditional materials. This Special Issue is devoted to studies on fundamental and applied aspects of fluid interfaces, trying to provide a comprehensive perspective on the current status of the research field.

The ongoing digitalization of the energy sector, which will make a large amount of data available, should not be viewed as a passive ICT application for energy technology or a threat to thermodynamics and fluid dynamics, in the light of the competition triggered by data mining and machine learning techniques. These new technologies must be posed on solid bases for the representation of energy systems and fluid machinery. Therefore, mathematical modelling is still relevant and its importance cannot be underestimated. The aim of this Special Issue was to collect contributions about mathematical modelling of energy systems and fluid machinery in order to build and consolidate the base of this knowledge.
