WebBernoulli’s equation is only applicable for ideal fluids. The flow in this type of vortex is forced to rotate about an axis so that the velocity is equal to V= ω . r where ω : angular velocity rad/s Applying Bernoulli’s equation across the radial streamlines. WebThe results of this analysis are shown in Figure 6.8 for a representative design flow coefficient ϕ *=0.8 at several different off-design flow coefficients ϕm, with r / rm =0.8 at the hub and r / rm =1.2 at the tip. It is apparent for values of ϕm < ϕ * that cx3 increases from hub to tip; conversely for ϕm > ϕ *, cx3 decreases towards the tip.
