The effect of separation distance between turbines on overall cluster performance were simulated using computational fluid dynamics software and we found that at a equivalent to two rotors, there was an improvement +8.06% in the average compared single, isolated turbine. A very small noted 12 rotor diameters. performances three individual pyramid- inverted pyramid-shaped vertical axis wind turb...

The discipline of Asset Management (AM), which focuses on the management physical assets in an integrated and holistic way along their life cycle, can be adopted by companies to promote sustainability since it enhances asset reliability availability for whole duration its usage. Within manufacturing industry, a relevant AM-related performance indicator is Overall Equipment Effectiveness (OEE), ...

The turbulent convective thermal transfer in channel heat exchangers (CHEs) is studied numerically via the CFD (Computational Fluid Dynamics) method. Deflectors are inserted on hot bottom walls of to enhance hydrothermal characteristics. Various shapes in-line deflectors considered, namely: rectangular (a/b = 0.00), cascaded rectangular-triangular 0.25, 0.50, and 0.75), triangular 1.00) shapes....

The increasing demand for energy and the concerns regarding environmental protection have been driving forces toward exploitation of renewable sources as a better alternative compared to conventional sources. Furthermore, enable an independent supply isolated locations or communities that lack access main electricity grid, additionally, they offer possibility use available beneficial individual...
