Flow Velocity Measurement Between Two Dimensional Roughnesses

Two-Dimensional Solute Transport with Exponential Initial Concentration Distribution and Varying Flow Velocity

The transport mechanism of contaminated groundwater has been a problematic issue for many decades, mainly due to the bad impact of the contaminants on the quality of the groundwater system. In this paper, the exact solution of two-dimensional advection-dispersion equation (ADE) is derived for a semi-infinite porous media with spatially dependent initial and uniform/flux boundary conditions. The...

Status of two-dimensional ion velocity measurement system in NSTX

A two-dimensional ion velocity measurement system is being developed under a US-JAPAN collaborative activity. The diagnostic is used to determine Doppler shifts from the intensity ratio of a visible line from the same light source, measured with two interference filters that have different transmission pass bands. A fast visible camera is used as two-dimensional detector. The system was tested ...

two-dimensional magma flow

exact solution for steady two-dimensional flow of an incompressible magma is obtained. themagmatic flow is studied by considering the magma as a second grade fluid. the governing partialdifferential equations are transformed to ordinary differential equations by symmetry transformations. resultsare discussed through graphs to understand the rheology of the flowing magma
