Shell-and-tube evaporators (VERD)

VERD Module Package



Program features:

Design and simulation of forced-circulation evaporators for pure substances without pre-heating of the liquid or super-heating of the vapor.

Available vaporizer types:

Sample Printout (PDF)

The calculation of the evaporation in vertical tubes is based on an incremental calculation procedure. For each increment the local heat flux, flow regime and pressure drop are determined.
The physical dimensions may be user-supplied or taken from standard tables. The tube sheet is generated precisely, with the possibility to be edited.
The physical properties of the media are supplied in separate property modules (see scope of delivery) Unpublished reference values can be determined by critical values.

Special features:

  • Scale drawing of the complete exchanger including dimensions
  • Detailed tube sheet generation
  • Optimization of new exchangers using given standard dimensions
  • Characterization of performance by multidimensional parameter studies
  • Export to  MS Excel in user-defined specification sheets
  • Calculation models for nucleate and convective boiling
  • Vibration analysis
  • Calculation of entry and exit regions in shell

Price of Standard Version: 3600 EUR plus VAT
