进行了一组计算模型试验，模拟了高速膛炮对垂直壁面的撞击。结果与O.H.进行的一系列实验测试进行了比较。欣斯代尔波浪研究实验室，俄勒冈州州立大学（OSU）的大型波浪水槽（LWF）[1]。实验测试包括在平底上行进的按比例的海啸实验孔[2]。实验孔是由孤立波在倾斜的海滩上传播并破碎到平坦的礁石上产生的[3]。在穿过礁石部分后，产生的钻孔撞击垂直壁。在实验中，测量了壁面上的合力和压力。该研究的目的是计算再生的实验孔流及其对垂直壁的影响。测试了两种计算域设置：1）溃坝[3- 8，10 -16]和2）新方法，其中在域入口处定义恒定高度和速度的进水。将两种数值方法与LWF实验数据进行比较[3]。版权所有© 2014 ASME
A set of computational model tests was carried out to simulate high velocity bore impact on a vertical wall. The results were compared to a series of experimental tests conducted at the O.H. Hinsdale Wave Research Laboratory, large wave flume (LWF) at Oregon State University (OSU) [1]. Experimental tests included scaled tsunami experimental bores that traveled over a flat bottom [2]. The experimental bores were generated by solitary waves propagating over a sloping beach and breaking onto a flat reef [3]. After traveling through the reef portion, the generated bore impacted a vertical wall. In the experiments the resulting forces and pressures on the wall were measured. The aim of the study was to computationally regenerate the experimental bore flow and its impact on the vertical wall. Two computational domain setups were tested: 1) a dam break [3–8,10–16] and 2) a new approach, in which constant height and velocity water inflow was defined at the inlet to the domain. The two numerical approaches were compared to the LWF experimental data [3].Copyright © 2014 by ASME
