Title: OPTIMIZED ENERGY RECOVERY DEVICE ROTOR
Abstract:
The present teachings include an energy recovery device usable in multiple applications, for example hydropower and vehicle power plant applications. In one aspect, an energy recovery device includes a housing having an inlet and an outlet in fluid communication with an internal cavity, and a pair of counter-rotating rotors having intermeshed lobes disposed within the housing internal cavity. Each rotor defines a transport volume between the housing and a pair of adjacent lobes and has a calculated maximum ideal twist angle below which the transport volume will be sealed from both the housing inlet and housing outlet. Each rotor also has an actual twist angle that exceeds the maximum ideal twist angle.
