AI Technical Summary
Existing temperature measurement technologies cannot simultaneously meet the comprehensive requirements of high spatial resolution, non-invasiveness, and long-term direct contact with fluid when measuring temperature on the inner wall of a flow channel. Traditional coating-type structures are susceptible to fluid erosion, swelling, or aging, which affects measurement stability and accuracy.
A structural temperature-responsive PMMA material is used to uniformly disperse temperature-sensitive fluorescent probe molecules in a PMMA matrix. The preparation method includes distillation, prepolymerization, and segmented heating polymerization to form a material with overall temperature response capability. This material is used as a flow channel structure to directly contact the fluid for optical measurement.
It achieves high spatial resolution optical measurement of temperature distribution on the flow channel wall, maintains material stability and measurement accuracy in the fluid environment, and is suitable for visual flow experiments and phase change heat transfer experiments.
