Water Vortex Power Plant: Fluid Resistance

  1. Oct 2, 2013 #1
    Hi, I would like some help for my final project. I'm trying to find an eqn for fluid resistance which is present on the frontal side of the blade as it spins:

    so far what i've come up by dimensional analysis is the drag force equation:

    F=Cd x ( ρ x v^2)/2 x A

    to get the fluid resistance:
    Fvortex - Fresistance =Ftorque

    Fvortex can be calculated by the force of an annulus eqn
    as for the Fturbine.. it can be acquired using torquemeter..

    My goal would to reduce the effect of the fluid resistance.

    Thanks in advance. :smile:
