In EnvironmentalScienceAssociates/tbsa: Turbine Blade Strike Analysis

Francis blade strike probability

Description

Calculates leading-edge blade strike probability from a Francis turbine

Usage

francis_strike(Q, H, D, D1, D2, rpm, eta, opt, xi, B, N, L, lambda = 0.2)

Arguments

Q	Turbine discharge (cfs)
H	Net head on the turbine (ft)
D	Nominal diameter (ft) of runner
D1	Diameter (ft) at the intake of the runner
D2	Diameter (ft) at the outlet of the runner
rpm	Runner revolutions per minute
eta	Turbine efficiency
opt	Ratio of turbine discharge at best efficiency to hydraulic capacity
xi	Ratio between Q with no exit swirl and Qopt
B	Runner height (ft) at inlet
N	Number of blades
L	Fish length (ft)
lambda	Actual mortality correlation; influenced by many factors including unit type and fish species
