摘要
为了研究海冰与波浪的相互作用,以单块非冻结模型冰为基础,通过试验研究了独立海冰的纵向运动,并与斯托克斯漂移进行对比.结果显示:海冰的纵向运动包括纵向平移运动和纵摇运动,平移运动可以分解成纵向的漂移运动及纯粹的纵荡运动;海冰的厚度、波长及波陡都会在一定程度上影响海冰的纵向运动.通过计算发现斯托克斯漂移与试验测量值随波陡的变化规律是一致的.
To study the interaction between sea ice and wave,based on a single non-refrigerated ice model,an experiment was carried out to study the longitudinal motion of sea ice in regular waves in this paper,and the results were compared with the stokes drift.The results indicate the longitudinal motion is consisted of translational and pitch motion.Translational motion can be divided into two parts,i.e.,drift and surge.Ice thickness,wavelength and wave steepness all have effect on the motion to a degree.Meanwhile through calculating,there is a certain relationship between theoretical stokes drift and measurement in this experiment,namely,they have the same change law.
