Abstract ross flow turbines are widely used as for driving micro-scale hydropower plants in rural areas, but their efficiency is still low because cross only use one nozzle. The utilization of the potential energy water not optimal yet to be converted into pressure and kinetic nozzles with high velocity hitting turbine blades. problem nozzle has an uneven blades, it effective converting power t...

Instantaneous cross sectional flow velocity profiles from early mitral flow in 10 healthy men were constructed by time interpolation of the velocity data from each point in sequentially delayed two dimensional digital Doppler ultrasound maps. This interpolation allows correction of the artificially produced skewness of velocities across the flow sector caused by the time taken to scan the flow ...
