【摘要】 按溢流坝面流场流动的特点，提出了等效势流场的假设．从理论上论述了等效势流场是成立的，并根据这一理论假设对溢流坝面二维流场进行水力计算，计算值与实验结果吻合．更多还原

【Abstract】 Based on the features of the flow field over spillweir dam,this paper proposes the hypothesis of the existence of equivalent potential flow field.The hypothesis is proved to be valid theoretically.According to the hypothesis,the numerical calculations of twodimensional flow field over spillweir dam are carried out.The calculating data agree well with experimental results.更多还原
