摘要
考虑空气阻力及卷吸掺气的影响,从相似理论出发分别建立了挑流水舌的一维和三维数学模型,并用相应的模型试验与原型观测资料进行了验证计算.验证计算成果表明,所建立的挑流水舌数学模型具有较强的预报能力,可为雾化问题和消能机理的深入研究提供较好的基础.
Based on the similarity theory the 1D and 3D models for aerated jets are suggested considering the air resistance and air entrainment. It seems that models suggested have higher predictive power by comparison with the results of model test and prototype observation data. The results will be useful for further studing problems of energy dissipation and jet flow atomization.
