Turbulent boundary layer over a deep cavity: friction coefficient and streamwise velocity components

Abstract: Deep cavities are present in car vehicles in numerous forms. Although drag downstream cavities have interested many authors, this aspect was never treated for particularly deep cavities. The objective of the present investigation is to study the effect of a deep cavity, characterized by its length-to-depth ratio L/H = 0.2, on both the skin friction coefficient and the statistic components of the streamwise velocity. Laser Doppler velocimetry (LDV) was used for the mean velocity and its statistic components mea… Show more

“…Low frequencies induced by shear-layer cavity resonance are characterized by large dynamic pressure loads and represent an important problem in many aeronautical applications [14][15][16][17][18]. El Hassan et al [19] have founded that such cavity configuration has different quantitative influence on the skin friction compared with square-cavity cases. Two "classes" of cavities are generally studied.…”
