using Xfoil parameters, panel code the airfoil parameters like. /rebates/&252fs1223-airfoil. Overall, all the simulations showed that at ultra-low Reynolds numbers quasi-steady solution does not necessarily have the same correlation with the time averaged results over the unsteady accurate solution. UIUC airfoil coordinates database is taken for the reference airfoil. The unsteady incompressible laminar flow over a Gurney flapped airfoil is investigated using three approaches namely unsteady accurate, unsteady inaccurate, and quasisteady. To further verify this approach, a different airfoil S1223. Therefore, it is deemed necessary to examine the previous investigations in the regime of ultra-low Reynolds numbers. The study uses the two-software integration methodology proposed in 1 i.e. Whether this is true for the regime of ultra-low Reynolds number is open to question. However, these investigations were conducted in regimes of medium to high Reynolds numbers where the flow is turbulent. Previous studies on Gurney flap have shown that the calculated aerodynamic coefficients such as lift and drag coefficients from quasi-steady approach are in good agreement with the time averaged values of these quantities in time accurate computations. Among these, some investigations have shown that quasi-steady approach does a good job on predicting the aerodynamic coefficients and physics of flow. Most of the investigations on Gurney flapped airfoils have modeled the flow using a quasisteady approach, resulting in time-averaged values with no information on the unsteady features of the flow. e CFD simulation of the s1223 airfoil was carried out using WORKBENCH.
