Abstract
A model based on the mixing length description is proposed for the pre diction of strongly non isothermal subsonic boundary layers. It is val idated on a set of experiments involving flows over plates heated up t o 1000 K. It is based on the hypothesis that the u'nu' profile is not modified by the heating, at least in the internal part of the flow. Re garding the isothermal case, the calculations lead to an appreciable i ncrease of the skin friction (about 30% at 950 K). (C) 1998 Elsevier S cience Ltd. All rights reserved.
