摘要 基于光滑粒子流体动力学(SPH)技术,提出水利类专业的流体虚拟仿真实验教学方法,并以水槽实验和港口实验为例分析该方法在波浪运动中的应用和效果。结果表明,SPH模拟得到的波形与理论波形吻合度较高,并且通过后处理可以高度还原实际的波浪运动形态。基于SPH的高精度和高仿真度的特性,将其应用于流体类虚拟仿真实验的建设中,可更好地满足结果可靠、内容精彩、技术先进等虚拟仿真实验建设要求,学生和专家的应用反馈也说明SPH技术优势明显,可很好地服务于流体类虚拟仿真实验教学。 based on SPH,a teaching method of fluid virtual emulation experiment for majors related to hydraulic engineering is proposed and analyzed by taking tank experiments and port experiments as examples.The results reveal that the waveform obtained by SPH emulation is in good agreement with the theoretical waveform,and the wave motion obtained by post-processing can highly reflect the actual wave motion form.On the basis of the characteristics of high precision and high emulation of SPH,and applying it to the fluid in the construction of virtual emulation experiment,it can better meet the reliable content wonderful technology advanced virtual emulation experiment of construction requirements.The application feedback of students and experts also shows that the advantage of SPH is obvious,it can serve the virtual emulation experiment teaching of fluid well.
