Sonic Nozzle Theory and Applications

Sonic Nozzles are designed and manufactured to control the gas flow rate within precise limits.

How it works?

Simply, thanks to compressible flow dynamics and special geometry of the nozzle, the velocity of the gas reaches to speed of sound (Mach1) at the throttle. At this condition flow is “CHOKED” in the other terms limited. Therefore, no further flow rate is allowed to flow through.

Unique Design for Every Application

Every application has its own requirement. The gas, pressure, flow rate and other conditions may vary. Therefore, Revindus designs the nozzles with help of their experience on compressible flow dynamics and powerful CFD package tool for each application. The unique design enables the nozzle to recover pressure effectively for use.

Manufacture for Precision

The flow rate is related to throat geometry and the surface. For each application, the surface quality and material might differ. Stainless steel and aluminum are the most popular sonic nozzle base material.
