Development of the oil film method of skin friction measurement for curved and free oriented surfaces

1999, 13(2): 1-9.

Abstract(133) PDF(7)

Abstract:
A further development of the skin friction measurement technique for free oriented and curved surfaces is described.A theoretical basis and experimental results of using the diffuse lighting to obtain equal thickness fringe patterns of a thin oil film are presented.A possibility of automatic detection of the surface streamline position by analysing the oil visualisation images is discussed.The results obtained show a possibility of using the oil film method for complicated 3D flows.

Abstract(98) PDF(2)

Abstract:
Present the two-layer model of thin shock layer-for approximate calculation of the inviscid flow over 3-d sharp bodies.A position of shock wave is defined numerically in this method.The method allows to define approximate values of gas-dynamic loads for calculation of aerodynamic characteristics on different body configurations.The using of this method practically removes restrictions on geometry of a sharp body,which exists for other known methods of hypersonic theory.Together with general aerodynamic characteristics,the method allows to obtain approximate flow fields around integrated schemes of vehicles at design and undesign regimes of the flight,and also it allows to make optimization their aerodynamic forms.
