DESCRIPTION:
SPHERA is a research code for computational fluid dynamics based on the Smoothed Particle Hydrodynamics (SPH) numerical method. This code has been validated in various fields, including:
 
Various types of floods, including those involving the transport of solid bodies, transport of bed load, flood protection works, flood-induced damage, and spatial coverage over areas of hundreds of square kilometers.
Landslides.
Sloshing motions in fuel tanks.
Surface waves.
Removal of sediment from water tanks.
Version 10 of SPHERA introduces new features allowing the simulation of linear marine wave propagation, their transported power, wave-structure interactions in the presence of floating solid bodies of complex shapes, and the use of thin-wall wave generators.
 
APPLICATIONS:
Possible applications include studies on floods, landslides, marine waves, impulse hydraulic turbines, transport of solid bodies and sediment in fluid flows.
 
USERS:
Developers of wave energy generation devices, researchers in the fields of the applications mentioned above.
