RT Journal Article ID 1e286794447002c0 A1 Zharkova, Galina A1 Kovrizhina, Valentina A1 Petrov, Alexander T1 SHEAR SENSITIVE LIQUID CRYSTALS FOR DIAGNOSTICS OF BOUNDARY LAYER STRUCTURE IN AERODYNAMICAL EXPERIMENT JF Visualization of Mechanical Processes: An International Online Journal JO VMP YR 2013 FD 2013-07-02 VO 3 IS 1 OP 0 K1 shear stress K1 visualization K1 measurements K1 liquid crystals AB The paper presents a brief introduction in the materials and methods of the panoramic diagnostics of shear stresses, induced by the flow on the model surface, by liquid crystals. Two mechano - optical effects in liquid crystals with helicoidal supermolecular structure (texture transition from con-focal to planar liquid crystal texture and shift of the selective reflection peak of initially planar texture), which form the bases of experimental techniques, are considered. The optical response of liquid crystals manufactured at ITAM was investigated by the spectral and colorimetric methods. Some results obtained under sub-sonic velocities give evidence of wide possibilities of the technique.
