Blowers play an important role in air-conditioning, furnaces, low pressure cooling and dust or fume extraction systems because they can achieve high pressures compared to fans. In this paper an industrial blower with three different volute geometries is investigated by using Computational Fluid Dynamics (CFD). And then two new volute geometries are modelled and analyzed based on the air flow through the blower. The numerical investigation revealed that blowers with modified volute geometries have better outlet velocities. For this work, impeller is modelled using Solid Works and meshed in ICEM CFD. The post processing is carried out using CFD POST. CFD simulations are performed using the commercial CFD software package FLUENT.
