Fossil fuels have been a means of energy source since a long time, and have tended to the needs of the large global population. These conventional sources are bound to deplete in the near future and hence there is a need for producing energy from renewable energy sources like solar, wind, geothermal, tidal etc. Technologies involving renewable energy are a growing subject of concern. The problem is...
Computational fluid dynamics (CFD) simulations have been completed to characterize the efficiency of tidal turbines. Efficiency is taken as the ratio of power production (i.e. useful electricity) to total power lost from the upstream incident flow energy. Many tidal turbine developers are considering ducted designs which accelerate the flow through the turbine, improving the power coefficient CP....
Viscous drag loss of oil-filled underwater BLDC motor need to be considered in the motor design. The calculation results of analytical formula do not really comply with experimental results. To obtain the accurate results, computational fluid dynamics (CFD) is used for calculating air gap flow field. The computed loss is in good agreement with the experimental result.
