通过定容燃烧弹(CVCC)试验,结合双色高温测量法与快速响应热电偶,实现了发动机工况下的柴油撞壁喷雾火焰瞬时对流传热与辐射传热同步测量,系统探讨了柴油撞壁喷雾火焰的瞬时辐射传热特性及其对总传热损失的影响.利用基于双色高温测量法建立的辐射发射率与辐射传热视角因子模型,分析了撞壁喷雾火焰的辐射传热占比.结果表明:在环境密度升至18 kg/m

、喷射压力增加到150 MPa、喷油脉宽延长到2.0 ms和环境温度升高至1 000 K的4种工况下,撞壁喷雾火焰的瞬时辐射传热占比相较于基准工况显著提升.环境密度增加显著提高了热流密度,但燃烧持续时间缩短;高喷射压力使热流峰值提前,并增加了辐射传热的占比;当环境温度超过900 K后,其对辐射传热峰值的影响减弱,表明高温下燃料蒸发与混合接近极限,燃烧速率趋于饱和.此外,撞壁喷雾火焰在火焰准稳态阶段具有更高的辐射传热占比.
