  • will do the exact without user intervention. The manual mode is still avialable too.
  • You can now perform a simulation study by changing any of the parameters under the Study scenarios below:
  • Study parameters 1:
  • Tube outer diameter, Tube number of passes, Tube length, Number of tubes, Baffle spacing
  • Study parameters 2:
  • Uses kern tube counts to iterated between Shell diameters to obtain the number of tubes for a given number of passes.
  • User can set the study parameters and the software will automate the calculation steps and add the final result to summary screen
  • where the changes between each can can be detected.
