【摘要】：针对单孔浸没式顶吹对液相的搅拌效果进行了实验研究。实验中设计并搭建了单孔浸没式顶吹水模实验平台,利用高速相机进行拍摄,通过改变进气量、喷管插入深度、喷管插入角度等条件,对不同工况的液相搅拌效果展开了研究。在不借助专业仪器且能准确、全面量化液相搅拌效果的前提下,根据图片特征提出了基于图片分块策略和NCC算法的相似度计算方法。结果表明:该相似度方法能准确全面地评价不同工况的搅拌效果;实验中,进气量越大、喷管插入越深搅拌越剧烈;喷管以不同倾斜角度插入喷吹,对搅拌效果无太大影响。
[Abstract]:In this paper, the effect of single hole immersion top blowing on liquid phase stirring was studied experimentally. In the experiment, the experimental platform of single hole immersion top blowing model was designed and built, and the high speed camera was used to shoot, and the air intake was changed. Under the conditions of nozzle insertion depth, nozzle insertion angle and other conditions, the liquid phase stirring effect under different working conditions was studied. Without the help of professional instruments and accuracy, the liquid phase stirring effect could be comprehensively quantified. According to the image features, the similarity calculation method based on the image partitioning strategy and NCC algorithm is proposed. The results show that the similarity method can accurately and comprehensively evaluate the mixing effect under different working conditions. In the experiment, the bigger the air intake is, the more intense the nozzle is. Nozzles with different inclined angles into the injection, no significant impact on the agitation effect.
