Meaning and Definition
A type of turbine where the working fluid (water, steam, or gas) changes direction as it passes through the runner, flowing both radially and axially.
A design combining features of radial (centrifugal) and axial flow turbines to achieve specific performance characteristics like a high power-to-size ratio or efficiency over a wider range of operating conditions.

- Using 'mixed-flow' to describe a system using two different fluids. It describes flow *path*, not fluid composition.
- Confusing it with a 'mixed-pressure turbine' (which uses steam at different pressures).
FAQ
Frequently Asked Questions
Yes, the Francis turbine is the most common and classic example of a mixed-flow hydraulic turbine, where water enters radially and exits axially.
They are widely used in medium-head hydropower plants, in some expanders for cryogenic applications, and in specialised turbochargers or small gas turbines where a compact, efficient design is needed.
It often provides a favourable balance between the high-flow, low-head capability of axial turbines and the high-head, lower-flow capability of radial turbines, resulting in a compact machine with good efficiency over a range of conditions.
Yes, the term can also describe pumps, compressors, or fans where the fluid path is similarly combined. The principle of 'mixed-flow' applies to various types of turbomachinery.
A type of turbine where the working fluid (water, steam, or gas) changes direction as it passes through the runner, flowing both radially and axially.
Mixed-flow turbine is usually technical, academic, engineering in register.
Mixed-flow turbine: in British English it is pronounced /mɪkst fləʊ ˈtɜːbaɪn/, and in American English it is pronounced /mɪkst floʊ ˈtɜːrbaɪn/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Imagine a turbine where water doesn't just go straight through (axial) or just spin outwards (radial), but does a MIXED dance: it spirals in and out as it flows.
Conceptual Metaphor
A CORKSCOW (corkscrew + screw): It combines the twisting, linear motion of a corkscrew (axial) with the outward-spreading motion of a centrifugal fan (radial).
