摘要
考虑环境湍流对烟气抬升具有增强烟气夹卷和促进烟气与环境空气间动、热量交换的双重作用，导出了中性层结条件下热烟气浮升的轨迹方程，并且无需对抬升的截止作任何假设，导得了理论的终极抬升公式。经与国内外烟气抬升实测资料对比，发现这些结果与实况基本一致。
onsidering the effects of both enhancing entrainment and intensifying the exchanges of momentum and heat between plume and ambient air. the trajectory equation of buoyant plume under neutral conditions is derived, and without any hypotheses on the rise termination the final rise prediction formula is obtained theoretically. Compared to the field experiments, the final rise formula simulass the observed final rise heights well.
