Version 15.0.35071 Release Notes

Key Highlights

  • Added thermal analysis capability for sensible heat transfer into or out of flowing fluids using two new devices: a Heat Source / Sink and a Heat Exchanger
  • Incorporated NIST REFPROP Database 23 for Fluid Property calculation
  • Added new Operating Modes for Devices 
  • New messages and identification of Over Controlled configurations with Automatic Solution for some configurations involving Sizing Pumps and Centrifugal Pumps

Benefits and Applications

    1. Determine if your piping system will meet the thermal and hydraulic requirements of your plant processes
    2. Determine how the thermal requirements of your process system establishes the hydraulic requirements of the auxiliary systems
    3. Determine if the heat exchanger you have or will be purchasing meets the thermal and hydraulic requirements of your plant processes
    4. Help size and select a heat exchanger to meet the thermal requirements of your plant processes
    5. Fluid properties sourced from a well-recognized standards organization
    6. Model more real world process controls
