Abstract
Corona-induced drag reduction was studied numerically over a finite region of a semi-infinite flat plate having small Ohmic surface conductivity for low Reynolds number flow (I characteristic) were evaluated by finite differencing schemes. The calculated results predict “corona thinning” of the boundary layer for a downstream ion flow and a corresponding reduction in drag, in agreement with previous theoretical studies. Various parameters of flow, electricity, and geometry, relating to corona-induced drag, are investigated.Keywords
