Numerical Solution of the Plane Problem of Thermo-Elasticity in Strains [PDF]

E3S Web of Conferences
In the work, within the framework of the Saint-Venant compatibility conditions, two plane problems of thermoelasticity with respect to deformations are formulated. The closedness of boundary value problems is achieved by considering equilibrium equations

SAINT-VENANT TYPE ESTIMATE FOR THE WAVE EQUATION

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2002
Bu çalışmada hızı azalan bir dalga denklemi için Uzaysal Azalım Kestirimi elde edilmiştir. Yük bölgesinden uzaklaşıldıkça son etkilerin, en azından kısa zaman aralıkları için çok hızlı bir şekilde azaldığı görülmüştür.

The influence of weight coefficients in the Preissman scheme on flows in the lower Odra river network using the Hec-Ras software

ITM Web of Conferences, 2018
Mathematical modelling of water flows processes in rivers and open channels for many years has been target of researches for hydrotechnics and hydrologists. For flows forecasting in open channels models based on one-dimensional equations are mostly used.

Online Model Identification Of Open-Channel System With High Order IDZ Model

MATEC Web of Conferences, 2018
In the control of open-channel, it is difficult to estimate wave propergation time because of the complexity of reflection, superposition and energy attenuation of shallow water waves. Although Saint-Venant equation have reasonable accuracy in describing

Time fractional Saint Venant equations reveal the physical basis of hydrograph retardation through model comparison and field data

Scientific Reports
River hydrodynamics are influenced by numerous factors that traditional models often fail to fully capture. Simulating complex hydrographs can benefit from parsimonious upscaling models, such as fractional derivative equations, that reduce the need to ...
