Off-design considerations through the properties of some pressure-ratio line of radial inflow turbines [PDF]
, 2008 Radial turbines are commonly used in applications involving operation through severe off-design conditions. The emergence of variable-geometry systems leads to the distinction between two off-design concepts: operational and geometric off-designs.
