Abstract

An unsteady boundary layer past an elastic flat plate with a leading fixed edge and a surging trailing edge was investigated utilizing both numerical and analytical methods. Analytical solutions for low and high frequencies were easily obtained along with conditions for the reduction of the skin friction drag. However, the analytical solution for intermediate frequencies were significantly more difficult. Since intermediate frequencies have some potential for application to engineering problems, a numerical method was chosen to analyze intermediate frequencies. The numerical results revealed a reduction of the skin friction drag from its steady state at intermediate frequencies.
