Fishways have a great ecological importance as they help mitigate the interruptions of fish migration routes. In the present work, the novel DualSPHysics v4.4 solver, based on the smoothed particle hydrodynamics method (SPH), has been applied to perform ...

Characterizing the refrigerant side of heat pump water heaters (HPWHs) can be intrusive and expensive. On the other hand, direct external measurement techniques can be unfeasible, particularly in commercial HPWHs for residential applications. Non-intrusi...

The ship?s wake in the presence of a shear flow of constant vorticity at a finite water depth is investigated by expanding the Whitham-Lighthill kinematic theory. It has been established that the structure of a wave ship wake radically depends on Froude ...

The expression ?follow the water? is used to recognize inside the universe, life as it exists on Earth. It is shown here that the expression ?follow the high subcritical water? can be used to recognize the components of life that formed prior to the emer...

Palm Oil Mill Effluent (POME) is well known as a difficult waste to manage by mill operators due to the large quantity produced at a time. Previous studies by our group has revealed that Sub-critical water (subCW) was able to be used as batch pre-treatme...
