摘要
A method and a gage for time-resolved skin-friction measurements. The gage is a composite structure comprised of a heated, flush-mounted, guard film and a hot wire mounted to an electrically insulated very low thermal conductivity material plug in the vicinity of the film and raised slightly above the plug surface. When the so constructed gage is calibrated in a laminar flow environment, it then has the ability to provide accurate readings of skin-friction in turbulent flow conditions.
