Frequently Asked Questions (1)
Q1. What are the contributions mentioned in the paper "Numerical investigation of an airfoil with a gurney flap" ?

Gurney flap sizes of 0. 5 %, 1. 0 %, 1. 25 %, 1. 5 %, 2. 0 %, and 3. 0 % of the airfoil chord were studied. The numerical solutions show the details of the flow structure at the trailing edge and provide a possible explanation for the increased aerodynamic performance.
