Available in PDF, EPUB and Kindle. Book excerpt: Experiment have been conducted to measure the local surface-shear stress and the average skin-friction coefficient in incompressible flow for a turbulent boundary layer on a smooth flat plate having zero pressure gradient. Data were obtained for a range of Reynolds numbers from 1 million to 45 million. The local surface-shear stress was measured by a floating-element skin-friction balance and also by a calibrated total head tube located on the surface of the test wall. The average skin-friction coefficient was obtained from boundary-layer velocity profiles.

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental definition of the local and integral values of friction drag of an aircraft or its elements is one of the basic problems of applied aerodynamics. We also should note the undoubted significance of this value for the development of modern lifting profiles and other aircraft elements, the description of near-wall flows in a form of similarity laws and testing of the numerical techniques of computation of flow around such aircrafts. However, to define this value accurately, one should have a clear conception of the possibilities and efficiency of application of one or another technique for a special case of body flow around. Though any experimental work assumes application of a certain concrete technique, including one for skin friction finding, the available literature information is as a rule uncoordinated, i.e., this information reflects only the level of availability of the technique applied. For this reason the researches like devoted to the development of new techniques and investigation of the efficiency of the known ones under various experimental conditions, become very important. The simplified layout gives a pictorial view of the main techniques of skin friction measurement, existing at the present time. The detailed consideration of these techniques is given in The present paper presents a comparative analysis of a number of direct and indirect measuring techniques wen they are applied in a incompressible turbulent boundary layer of a flat plate under the conditions of formation of a unfavorable (positive) and favorable (negative) streamwise pressure gradients on the plate surface, and also in plate gradient-free flow around.

This book was released on 1951 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental data for skin friction of turbulent boundary layers under adverse pressure gradient are presented from several sources. Data obtained by momentum balance are shown to follow a trend opposite to that of data obtained by a hot-wire and heat-transfer methods. A new integral energy parameter and a new momentum thickness are introduced. The momentum equation and total-head measuring techniques are discussed in relation to skin-friction computation.

Calibration of the tube was made by a means of a floating-element type of skin-friction balance. Calibration conditions range in Reynolds number based on free-stream conditions from 70,000 to 875,000.

This book was released on 1964 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work done on the use of the surface impact probe, or Preston tube, method of measuring skin friction in turbulent, compressible boundary layers. The theory for incompressible flow was extended to the case of adiabatic, compressible flow, and the extended theory was experimentally shown to be valid. It has also been demonstrated that the extension is applicable to adiabatic flow with moderate adverse pressure gradients. Experimental and theoretical efforts to apply the impact probe method to compressible flows with moderate, aerodynamic heating were only partially successful. (Author).
