Recently, the world's first fluid wall shear stress tester was successfully developed at the Key Laboratory of Airborne Micro-nano System of Ministry of Education, Northwestern Polytechnical University.
The project “Development and Application of Fluid Wall Shear Stress Tester” is a national major scientific instrument and equipment development project led by the Key Laboratory of Aerospace Micro-nano System Ministry of Education in 2013. The project is aimed at major engineering needs and broad market prospects. In the development of fluid wall shear testing instruments to solve long-term aerodynamic/hydraulic experiments, the wall shear stress cannot effectively measure problems, formulate standards, establish standards, and enhance the independent innovation and core competitiveness of China's experimental fluid mechanics important scientific instruments and equipment.
