概要:

application/pdf<br />Journal Article<br />An experimental study on an intermittent fuel spray initiated from a swirl injector proposed for direct injection spark ignition (DISI) engines has been carried out in order to clarify the effects of back pressure and ambient temperature. The measurements have been made in a constant volume chamber in which maximum pressure and temperature reach 1.1MPa and 423K, respectively. Visualization of the spray is performed by … a high speed CCD video camera with laser sheet technique. Droplet velocity and diameter are acquired by phase Doppler anemometry (PDA), and processed by a time-dividing method which divides the phase matched spray information into five distinct periods. The effects of ambient temperature on the droplet velocity appear at the tip of the spray. The decrease in Sauter mean diameter D_<32> is observed at core region of the sprays when the ambient temperature is high conditions under both back pressures. 続きを見る
