چکیده

The energy consumption of artificial ground freezing applications results from the necessary (consumed) refrigeration capacity. The determination of the refrigeration capacity requires the numerical modeling of heat transfer processes within the freeze pipe. Therefore a new module has been implemented in the Finite Difference Program SHEMAT. An approach for calculating the heat transfer processes and finally the refrigeration capacity is presented in this paper. Thus numerical simulations are carried out to determine the influence of groundwater flow on the refrigeration capacity and the related energy consumption for artifical ground freezing applications. RÉSUMÉ : La consommation d’énergie des applications pour la congélation artificielle du sol résulte de la capacité nécessaire de réfrigération. La détermination de cette capacité de réfrigération exige un modèle numérique des processus de transfert de la chaleur dans le tuyau de congélation. C’est pourquoi un nouveau module a été implémenté dans le programme SHEMAT. Une approche pour calculer le transfert de la chaleur et finalement la capacité de réfrigération est présentée dans cet exposé. Ainsi, des simulations numérique ont été réalisées pour déterminer l’influence du flux des eaux souterraines sur la capacité de réfrigération et la consommation d’énergie qui en résulte des applications pour la congélation artificielle du sol.

Numerical Simulation of Seepage Flow through Dam Foundation Using Smooth Particle Hydrodynamics Method (RESEARCH NOTE)

In this paper, a mesh-free approach called smooth particle hydrodynamics (SPH) is proposed to analyze the seepage problem in porous media. In this method, computational domain is discredited by some nodes, and there is no need for background mesh; therefore, it is a truly meshless method. The method was applied to analyze seepage flow through a concrete dam foundation. Using the SPH method, the...

Use of Numerical Simulation to Measure the Effect of Relief Wells for Decreasing Uplift in a Homogeneous Earth Dam

Relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. Placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. Relief wells are often used in combina...

Numerical Simulation and Estimation of the Transvers Macrodispersivity Coefficient of Aqueous Phase (Miscible) Contaminants of Salt Water in a Heterogeneous and Homogeneous Porous Media

Deterioration of groundwater resources in coastal regions due to the progression of saline water in aquifers in these regions is currently one of the important issues in providing water needs in these areas. In coastal regions, saline water enters the aquifer from below in shape of wedge. Due to the difference in the density between fresh and salty water, an interface zone forms between two flu...

Assessment of water leakage through the right abutment of the Seymareh dam

One of the major issues in dam construction is water seepage, post impounding. Assessment and prediction of the amount of waterleakage can be useful in preventing such events. The Seymareh dam has been constructed on the Seymareh River in Ilam province,Southwest of Iran. The dam controls the floods and generates hydroelectric power. It is already under impoundment and the seepageproblem is bein...
