Abstract
This paper reports the measurement of three-dimensional velocity field in a spray combustion chamber with and without combustion using a combined use of planar PIV technique and with a rotary shutter mechanism. An uncertainty analysis has been carried out using artificial images, which include the influence of luminous noise generated by the spray combustion. The present results indicate that the flow pattern inside the combustion chamber is modified to strengthen the vertical flow motion relative to the horizontal one under the influence of combustion.
