Computational Fluid Dynamics Analysis of Leading Edge Roughness Devices

Mentor: Valana Wells
FURI: Spring 2019

The objective for this research was to model the effects of a wing with leading-edge roughness device’s on coefficient of lift and drag when at high angles of attack near stall, the addition of which potentially increases the stall angle and reduces stall speed. This research was conducted using Computational Fluid Dynamics, modeling an airfoil with teardrop shaped pimples on the leading-edge to determine the feasibility of the devices for use on aircraft. The impact of this research could potentially increase an aircraft’s lift capability and the overall efficiency of the aircraft.

CFD Analysis of Changing Surface Roughness in Response to Flight Conditions

Mentor: Valana Wells
FURI: Fall 2018

The motivation for this research is to use varying surface roughness to dynamically increase lift-coefficient at high angles of attack near stall, as well as increase the stall angle and reduce stall speed. The scope of this research will be to analyze through Computational Fluid Dynamics the viscous flow over an airfoil with a rough surface to determine the optimum placement of roughness device(s) and the degree to which they are deployed under different flight conditions. This research will provide data to inform the engineering of devices to increase an aircraft’s lift capability and the overall efficiency of the aircraft.
