Pressure Sensitive Paint technique for pressure measurement Pressure sensitive paint is a technique used for measuring the level of air pressure or the concentration of oxygen in aerodynamic environments (Sullivan & Liu 2004). Research has indicated that the pressure sensitive paint technique is the most effective method for measuring pressure in aerodynamic environments…
This technique is also sensitive to extreme temperatures because it affects the transition of the luminescent molecules (Mantel 2005). The PSP material is also used to develop coat for self adhesive tape and decals. This approach is preferable as it’s quick and easy during experimentation. It’s also reduces the time consumed for surface preparation as well as cost minimization (Mantel 2005). Pressure sensitive paint technique is also used in wind tunnels for pressure management. Due to the ability of this technique to provide field management, it produces global surface maps with better resolutions. Producing high quality global surface maps however requires a clear understanding of the e internal mechanisms of the technique as well as the functions, properties and experimental setup (Sullivan & Liu 2004). This technique has been found to be easier, more accurate faster and cost effective as compared to the use of pressure ports and computational fluid dynamics for external pressure management. ...
