Nonlinear model equations for waves in a stratified fluid

Model Equations for Waves in Nonlinear Dispersive Systems

The present discussion focuses on models for unidirectional wave propagation in which nonlinear, dispersive and dissipative effects are simulated realistically and in such a way that shock formation and other singular behaviour is avoided. While comparatively narrow, the range of discussion nevertheless covers a number of interesting and challenging scientific issues, several of which still rem...

Internal Waves and Boundary Layers in a Density-stratified Fluid

Internal tides, generated in the density-stratified ocean by the oscillation of the barotropic tide over bottom topography, play a crucial role in the energy balance of the Earth–Moon system [1]. This has led to a recent revival of the classical topic of internal gravity wave generation by oscillating bodies. Wave energy dissipates owing to wave breaking and suband superharmonic excitation, at ...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
