Effect on Efficiency of Lobe Performance in a Roots Blower

A Roots blower is a mechanical device for moving air or other gases. As the flow process is highly complex in roots blower operation, it is necessary to analyses efficiency of lobes and develop the geometry of roots and casing to reduce the flow loss significantly. In the present thesis, the methodology to find near optimum combination of blower operating variables of performance.Roots blower are positive displacement device. In this study, roots blower is used to control the room conditions like temperature, moisture control, mist and transfer low volume intake into the system, increase the power efficiency of the engine. It is reliable, economical and having low maintenance cost.A roots blower performance depends on quality of air intake and geometry used. The quality of air major impact to the lobe arrangement and effect on temperature increase, reduced thickness of lobes and impact on performance of roots blower.
