摘要
基于势流理论对分层流中运动物体产生的内波进行了分析,其中采用线性自由面条件,通过傅里叶变换法,建立了体效应内波的预报模型,并对跃变分层中水下卵形体的内波进行了计算和分析。计算结果与文献理论结果吻合良好,表明了本研究建立的体效应内波预报模型的正确性。
Internal wave generated by a moving body in the stratified fluids was analyzed using potential theory. A theoretical model of body generated internal wave was established using the linearized free surface condition and Fourier transform method. Internal wave generated by a moving egg-shaped body in the pycnocline was analyzed. Calculation results agree well with that from literatures and it proves our theoretical model's validity.
