Abstract
The chemical sublimation technique using naphthalene was applied to detect boundary layer transition on a flat plate at low speeds. Comparison of location characterising the end of transition as detected by this technique with those mane employing velocity profile and transitional13; i ntermittency measurements showed satisfactory agreement. The above technique was also successfully applied in an exploratory test on the wing of the NAL light aircraft model at low speeds. To gain experience in the use of hot-films, a hot-film gauge was also calibrated in a zero pressure gradient turbulent boundary layer. These13; results are described in the Appendix.
