Although EasyCFD is a simple software, mainly oriented for didactic or educational purposes, it may become a valuable tool for a first analysis in practical situations. Nov 6, 2014 - 19 min - Uploaded by Civiliumسيفيليوم تقدم شرح soil mechanics للتواصل مع غيث خريسات www.facebook.

A flownet is a graphical representation of two- steady-state flow through. Construction of a flownet is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in, or as a first check for problems of flow under hydraulic structures like or sheet walls. As such, a grid obtained by drawing a series of equipotential lines is called a flownet. The flownet is an important tool in analysing two-dimensional irrotational flow problems. Flow net technique is a graphical representation method. Contents • • • • • • • Basic method [ ] The method consists of filling the flow area with stream and equipotential lines, which are everywhere to each other, making a.

Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam and the top of an impermeable bedrock layer), which define the sides of the outermost streamtubes (see figure 1 for a stereotypical flownet example). Mathematically, the process of constructing a flownet consists of the two harmonic or of potential and. These functions both satisfy the and the contour lines represent lines of constant head (equipotentials) and lines tangent to flowpaths (streamlines). Together, the potential function and the stream function form the, where the potential is the real part, and the stream function is the imaginary part.

This video introduces the use of flownets in geotechnical engineering. Water flow through soil has a significant impact on the soil properties and behaviour - these impacts are often assessed today using proprietary software. However, an ability to construct a basic flownet is a valuable first step in evaluating ground water flow problems and is particularly useful for getting a “feel” for how the problem should be modelled. The fundamentals of constructing a flownet and its geotechnical applications are the discussed in this video. Videos designed and presented by Declan Phillips PhD P.E.
