    ON THE HYDRODYNAMIC STABILITY OF NON-LINEAR WAVES
    (Al-Neelain University, 2010) Amna Mohammed Osman Elzebair
    ABSTRACT This work is a discussion of some of the fundamental ideas involved in current work on the nonlinear theory of hydrodynamic stability. It also describes a stability of nonlinear waves from hydrodynamic stability , the logistic equation in the theory of population growth, bifurcation theory, structural stability, energy method and maximum and .minimum energy in vortex motion The work also suggests a thermal stability, convective stability, based .on the equations of motion and particular stability characteristics 111 الخـلاصـــــة تتناول الدراسة النظرية الا خطية للاستقرار الهيدروديناميكي للتدفق الثابت متناولة نظرية لانداو بالتفصيل كما تتناول الدراسة أيضا الأنظمة التفاضلية التي تحكم الاستقرار والمفاهيم الأساسية للاستقرار الا خطي الي جانب تناول نظرية التشعيب والمعادلات التي تحكم الاستقرار . يدرس العمل أيضاً الانتقال الحراري وبعض المعادلات الهامة التي تحكم التوصيل الحراري . .
