title = "Numerical study of bumpy airfoil flow control for low Reynolds numbers",
abstract = "This paper discusses results from two dimensional simulations of a {"}smooth{"} Eppler 398 wing profile and an inflatable or {"}bumpy{"} Eppler 398 wing profile. A discussion on computed flow fields follows for a number of test cases in an effort to understand the unique behavior seen in wind tunnel tests of inflatable wings. Experimental observations suggest that the flow over the {"}bumpy{"} profile has less separation than that of the {"}smooth{"} profile for a few low Reynolds number cases. Numerical studies suggest that the flow over the {"}bumpy{"} airfoil is more unsteady than that over the {"}smooth{"} airfoils and that the amount of lift generated by the {"}bumpy{"} airfoils is less than its smooth counterparts for a range of angles of attack at the low Reynolds numbers studied.",
