| Outline of Final Research Achievements |
Three types of new sensors for measurements of wall shear stresses in turbulent shear flows: a hot-film sensor made of Silicon wafer (referred to as a SW sensor), a floating element sensor (referred to as a FE sensor), and a patch-type hot-film sensor made of polyimide (referred to as a patch-type sensor), and their control circuits have been developed. Frequency responses and SN ratios of the sensors are investigated. Further, simultaneous measurement of wall shear stress and velocity field are performed in a wall jet using the SW sensor and the patch-type sensor.
