内容記述 | We have investigated a turbulent combustion by PIV (Particle Image Velocimetry) technique. Comparing with LDV data, the validity of PIV measurement has been confirmed. Especially, the conditions of sampling number and spatial resolution have been revealed to obtain reliable data by PIV. Based on the velocity fields in cold flow and combustion, the interaction between flame and flow has been discussed. It is observed that the flow field is changed by combustion and the turbulence is reduced. For determining statistic quantities such as mean velocity and rms of velocity fluctuation, the sampling number of 1000 is needed. Moreover, the velocity correlation coefficient is evaluated to obtain the integral length scale of the flow. For both cold flow and combustion, the estimated scale by PIV is very close to that by LDV based on the assumption of Taylor's hypothesis. Resultantly, the special resolution in this study is about 6 times smaller than the integral length scale. | |||||
