Construction of pressure-sensitive paint measurement system and calibration for homemade paint

Pressure-sensitive paint (PSP) technique is a new-concept measurement technology developed since 1980's, which can help to achieve global pressure distribution of interest surface in flow field without interferential effect to the field. A set of PSP measurement system has been established based on existing conditions of experiments for pressure measurement of global interest surface inside the fields of turbo-machinery and internal aerodynamics. The calibration of homemade paint and its analysis have been conducted with the purpose of verification of the measurement system and further knowledge of the paint. All that have been finished previously can be considered as the basis of next work.
