Abstract

Skin friction measurements were made in a 'two-dimensional13; turbulent boundary layer under zero pressure gradient by several techniques . The techniques include devices using razor blade ., and sub layer fence . The classical clauser chart method and Bradshaw's scheme were also used in all the tests reported here . The tests were conducted at a unit Reynolds number of 1 .4 million per metre . The applicability of these techniques to a confluent boundary layer was evaluated . 13; A new and simple method of making the sub-layer fence described here was tested for its applicability as a skin friction measuring device . This simple . _device was found to be as good quot;as the regular machined fence generally used for such accurate measurement of wall shear stress .
