The diffuser plays an indispensable role in setting the useable flow range and efficiency for centrifugal machinery. Key aspects of the history and design of such diffusers are overviewed followed by a look at current, novel ideas for better systems. Improved machinery can be expected in the coming years due to decades of development work in this field.
