In the era of scientific and technological advancements, the global trend toward green initiatives is gaining momentum. The transition to greener energy sources is a significant aspect of this motivation. Currently, fossil fuel-powered engines are gradually being replaced by electric motors as the primary energy source. Electric ducted fans used for green airborne machines are an obvious example. This article introduces the application of a Rotor Shroud Air Bleeding Channel to upsurge thrust for the electric Propulsion Ducted Fan. Three geometric constraints of this exhaust channel, including bleeding position, width, and angle, are investigated to reduce the influence of leakage flow and vortex at the fan tip zone. The k-ω based SST turbulence model is used in ANSYS-CFX run on a high-quality grid. The simulation results show a positive prediction such as the largest thrust increase of 6.38% at the maximum rotation speed of 10,000 rpm, equivalent to about 7 kg when compared to the original case. Changing the shape of the airflow bleeding channel, exploiting optimization methods, or integrating the recirculation channel are considered viable development directions.
