Fluid dynamics calculation software WINDURCH

for hydraulic and thermal installations

Program for the evaluation of permeability tests acc. to DIN 18130. The WinDurch program contains various modules: Determination acc. to DIN 18130 – Part 1 (1998-05) Compression permeability device with static load of the test specimen Examination in a test cylinder with standpipes Examination in the triaxial cell Determination acc. to DIN 18130 (1989-11) Section 9 – fine-grained soil (const. hydraulic gradient) Section 10 – coarse-grained soil (varying hydraulic gradient) individual tests Section 10 – coarse-grained soil (varying hydraulic gradient) sequential test The data are entered into the form and can be calculated at the push of a button. Input: General data concerning the project description (such as building project, sampling point, date etc.), which can also be copied from other projects. Selection menu for various evaluations acc. to DIN 18130. Input of general data for the test specimen, its density, and the water contents before and after the test, saturation pressure, hydraulic gradient as well as specifications concerning the flow procedure. Input of general test data, such as diameter and/or cross section of the standpipe. Data transfer from an external ASCII-file possible on request. Compression permeability device with static load of the test specimen Starting time. Time of the reading alternatively relative to the previous measured value or absolute since beginning of test. Water head and reading at beginning of test. Alternatively reading or water head. Examination in a test cylinder with standpipes Starting time. Time of the reading alternatively relative to the previous measured value or absolute since beginning of test. Readings h1 and h2
