Persamaan Momentum untuk Aliran Berakselerasi Tinggi dengan Aplikasi pada Pemodelan Gelombang Pendek

Abstract

In this reserach, momentum equation for high accelerated flow is developed. The equation is developed by using spatial differentiation for high accelerated flow in Euler's momentum equation. With this method, fluid acceleration not only excited by force on its direction but also but also forces from other directions. The resulted momentum equation is used to short water wave modeling, where as surface water equation is a superposition between continuitya and energy coservtion equations. The equation is solved numerically where execution of the model show that the model can simulate wave shoaling and breaking where the resulted wave length is much smaller than wave length of linear's water wave theory.
