Design, Construction and Performance of Spiral Diffuser

Mohan Gautam, Ankit Tiwari, Om Parkash, Thakur Sanjay Kumar

Abstract


Diffuser is a device which increases the pressure of the fluid on the expense of kinetic head.
These are commonly used in air conditioners, jet engines, gas turbines etc. Diffusers serve
several purposes such as to deliver both conditioning and ventilating air and distribute the
flow of air in the desired directions etc. In the present work, the performance of spiral
diffuser has been analyzed. The objective of the present investigation is to study the flow and
pressure recovery characteristics of Spiral shaped curved diffuser. The flow and performance
characteristics of this diffuser are very complicated because of the combined effect of
geometrical curvature and flow diffusion. They have lower performance as compared to
straight wall diffusers but, have an advantage of occupying less space with respect to straight
wall diffusers.
