It seems leaf blowers are everywhere in our neighborhoods, very often disturbingly noisy. There is a need for excellent aerodynamic and aeroacoustics design for such devices.
Three leaf blower configurations were designed using CFturbo: a single-stage design, a dual-stage design, and a contra-rotating design. The goal of the design study is to minimize the rotational speed required to meet the performance targets and minimize the swirl downstream of the nozzle.
