Investigations on the Effects of Trip Wires on the Performances of a Rectangular Wing

, 2016
This work investigates the effects of small cylindrical elements (“trip wires”) on the aerodynamic performances of a rectangular wing at Reynolds numbers between 5 × 104 and 2 × 105. The diameter and position of the perturbing cylinders are changed in order to evaluate modifications in drag and lift coefficients in comparison to the unperturbed wing ...
