Fluid systems are mechanical systems, since they obey Newton’s laws. They store energy as kinetic energy (energy of motion) or strain energy (energy of elastic deformation). Kinetic energy is dissipated as heat through viscous friction, which is lost from the system.
A fluid machine is a device which converts the energy stored by a fluid into mechanical energy or vice versa . The energy stored by a fluid mass appears in the form of potential, kinetic and intermolecular energy. The mechanical energy, on the other hand, is usually transmitted by a rotating shaft.
An additional mode of energy storage is the work that is done by those forces, which are exerted by fluids on their containers. One important form of energy storage in low pressure systems is the elevation of liquid against gravity. Mechanical engineers work with many different types of fluid systems.
1.2. Energy storage systems (ESS) Energy storage systems (ESSs) successfully mitigate renewable energy intermittency and unreliability. These systems function in charge, storage and discharging modes thereby offering effective energy management, less spillage and a stable power grid.
Mechanical energy exists in two primary forms: potential and kinetic. Systems such as pumped hydro storage (PHS) and compressed air energy storage (CAES) store potential energy while flywheel energy storage systems (FESs) store kinetic energy.
Fluids, both liquids and gases, are used in machine design to transmit power, store energy, and actuate mechanisms. Fluids have mass and are compressible. Thus, they store both kinetic and strain energy. Further, fluids are generally confined within containers such as tubes, pipes, tanks, and cylinders.
