    Application of potential flow theory to free surface flow problem
    (Mohamed Boudiaf University of M'sila, 2025-06-15) Asma, Khazari; Supervisor: Abdelkader, Gasmi
    This thesis addresses the application of potential flow theory) to free surface flow problems, using both analytical and numerical solutions. The research focuses on solving the fundamental equations (continuity, Bernoulli, Laplace) under specific boundary conditions, with particular emphasis on the Boundary Element Method (BEM) as an accurate and computationally efficient tool. This study provides practical insights for the fields of hydraulic engineering and aerodynamics.

    Numerical and Analytical Approaches to freesurface and potential flow
    (Mohamed Boudiaf University of M'sila, 2025-06-15) Chaima, Mammeri; Supervisor: Abdelkader, Gasmi
    This work deals with the study of a free surface flow of an ideal, two-dimensional, steady and, irrotational fluid inside a horizontal channel huid is assumed to be incompressible, and surface tension effects are neglected, while channel with an obstacle on the bottom. The gravity is taken into is based on the long-wave approximation, using a small parameter : 0 < epsilon = (H/l) ^ 2 << 1 The bottom profile function y = b(x) and the free surface by y = H + eta(x, t) where 7 is the main unknown of our problem.
