Fuel System Library - Release Information

Release Notes for Fuel System Library 4.2

Fuel System Library 4.2 is part of Modelon’s 2017.2 release.  

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

New features

  • Implemented free convection heat transfer correlation based on Nusselt number for the complex tank model
  • Implemented 3D visualization for pipes, boundary conditions, valves, simple tank and pumps

Improvements

  • Added compressibility to non-evaporating and evaporating fuels. Package constant ‘legacyConstants’ when set true, will implement legacy density code for JetA_RT, otherwise it will use a mixture of the CRC data for temperature dependence and the legacy code for pressure dependence. Evaporating fuels will use the same pressure dependence as the non-evaporating fuels.

Fixed issues

  • Fixed initialization of volumes for ‘liquidAtStart’. Reverted to old implementation that uses a lower limit for the gas fraction.
