O método dos elementos de conservação espaço-tempo e elementos de solução (CE/SE) é um método multidimensional robusto e acurado proposto por Chang em 1991. Fundamentado na resolução de leis de conservação, tal método é caracterizado por explorar, de... see more

Torsional problems commonly arise in frame structural members subjected to unsym­metrical loading. Saint-Venant proposed a semi inverse method to develop the exact theory of torsional bars of general cross sections. However, the solution to the problem us... see more

Ondas de cheia em canais e ondas produzidas por manobras em comportas são alguns fenômenos simulados com as equações de Saint-Venant em aplicações de engenharia. Um novo código foi desenvolvido para a solução dessas equações aplicadas a um canal trapezoid... see more

This work deals with the numerical modeling of the hydraulic jump problem in a rectangular channel by the finite element method. The determination and knowledge of the jump characteristics; position, length, height and energy dissipation, are of prime imp... see more

The purpose of this work is the resolution of the Saint Venant two-dimensional equations governing unsteady and supercritical flows crossing a hydraulic transition corresponding to a symmetrical rectilinear expansion which is generally used in the free su... see more

Banjir merupakan suatu kejadian yang ditandai dengan naiknya muka air melebihi volume tampung air semisal sungai atau saluran air. Adapun banjir itu sering terjadi salah satunya di Indonesia karena Indonesia merupakan Negara tropis dan beberapa daerah pun... see more

A modelagem hidrodinâmica fluvial tem sido amplamente utilizada como uma ferramenta computacional para estimar o potencial hidrocinético de reservatórios de jusante de UHEs, ou seja, aproveitando a energia remanescente. O presente estudo avaliou o potenci... see more
