HYDRAULIC MACHINES

MAIN FEATURES

  • Selection of an unlimited number of hydraulic machines for each analysis
  • Description of each hydraulic machine through data supplied from manufacturers (e.g. rotational speed, volume flow rate, etc. at best efficiency point)
  • Definition of non-dimensional quantities (rotational speed, volume flow rate, torque, head, etc.)
  • Definition of non-dimensional relationships based on similarity laws
  • Computation of non-dimensional characteristic curves (i.e. Suter curves) for the full range of operation  using analytical interpolation techniques
  • Comparison of analytical functions with original data from manufacturers (e.g. head versus discharge curve, power versus discharge curve, etc.)
  • Visualisation of results
  • Suitable for designing and testing

OPTIONS FOR IO OPERATIONS

  • Microsoft Excel Spreadsheet Files (xlsx)

OPTIONS FOR GRAPHICS

  • Standard Image Formats (jpeg, tiff)
  • Portable Document Format (pdf)

TEST CASES

Figure 1 and Figure 2 show some simulation results comparing analytical curves and available data.
