Abstract
ABSTRACTThis work aims to study and simulate the behavior of flow over SAFAT-01’s wingusing numerical simulation based on solving Reynolds’s Averaged Navier-Stokesequations coupled with K- turbulent model. The wing model is simple rectangularwith elliptical ends. In the present work, aerodynamics characteristics and differentflow phenomena were predicted at different design conditions (e.g. at different anglesof attack) and at Re=5.2×106. The present study analysis the vortices which occurover wing and captured their effective regions at critical design conditions.This study indicates that the maximum lift coefficient for SAFAT-01’s wing is 1.44occurred at stall angle of attack 12o, maximum lift to drag ratio (L/D) is 26 whichoccurs at -4 o, and the zero lift drag coefficient is 0.0142. To validate this numericalsimulation, a typical wing which found in Ref. [3] was analyzed, a comparisonbetween predicted results and available results indicate that this numerical simulationhas high ability for predicting the aerodynamics characteristics.
