EXTENDED SEEPAGE FLOW ANALYSIS CONSIDERING UNDERGROUND CAVITY

Two-Phase Flow on a Gabion Stepped Spillway: Cavity and Seepage Air-Water Motion

On a stepped spillway, the steps contribute to some dissipation of the turbulent kinetic energy, while free-surface aeration can be very intense. The aim of this study is to investigate the two-phase flow properties on a gabion stepped spillway, including both free-surface and seepage flows, as well as the bubbly flow interactions at the gabion interface. Detailed measurements were conducted in...

Stochastic Analysis of Seepage through Natural Alluvial Deposits Considering Mechanical Anisotropy

The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...

Two and Three-Dimensional Seepage Analysis of Earth Dams Considering Horizontal Filter Blanket Effects (RESEARCH NOTE)

Seismic Analysis of Building with Underground Stories Considering Soil Structure Interaction

Current building codes lack explicit recommendations on how to simulate the seismic performance of high-rise buildings with multiple underground stories. Designers are typically basing their analyses on subjective engineering judgment and experience. Recent researches shows that seismic response of buildings with basement walls is a complicated phenomenon. This paper studies the seismic behavio...

Numerical study of a combined convection flow in a cavity filled with nanofluid considering effects of diameter of nanoparticles and cavity inclination angles

The present paper focuses on problem of mixed convection fluid flow and heat transfer of Al2O3-water nanofluid with temperature and nanoparticles concentration dependent thermal conductivity and effective viscosity inside Lid-driven cavity having a hot rectangular obstacle. The governing equations are discretized using the finite volume method while the SIMPLER algorithm is employed to couple v...
