Numerical Simulation of Effect of Drain Pipe in Uplift Force and Exit Hydraulic Gradient in Gravity Dams

In this study, the effects of diameter and location of drain pipe in uplift force and exit hydraulic gradient in the foundation of gravity dams are investigated. For this purpose, a numerical model of gravity dam foundation is simulated using finite elements method. The results indicate that drain pipe under the gravity dam reduces the uplift force and exit hydraulic gradient. Location of the d...

The influence of pipe length in direct numerical simulation

A direct numerical simulation (DNS) of fully developed turbulent pipe flow is performed at Reτ ≈ 170 and 500 to examine the effect of the streamwise domain length on the convergence of turbulence statistics. Computational domain lengths vary from the πδ to 20πδ. Lower order statistics such as mean flow, turbulence intensities, Reynolds stress, correlations and higher order statistics including ...

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
