TITLE : XYLEN FLOW IN A CONVERGENT-DIVERGENT DUCT

BY : S Zhubrin - CHAM-MEI

DETAILS :

• This case is concerned with flow and heat transfer in a symetrical converging-diverging duct filled with a fluid with highly varying properties.

• The properties that depend heavily on the temperature include the density, thermal conductivity, viscosity, heat capacity and Prandtl number.

• PLANT is used to introduce the property correlations into the calculation procedure.

Further details of PLANT:

• PLANT is a PHOENICS add-on which allows users to change the coding within certain GROUND groups and sections using PIL instructions in the Q1 file.

• PLANT can include GROUND coding for non-linear property correlations, interphase transport features, initial fields, non-linear source laws and output control calculations.

• PLANT is intended for use by those with a need to include GROUND routines but who either lack the necessary FORTRAN knowledge or who wish to same time by placing the necessary commands in the Q1 file

• PLANT adds the required coding into GROUND and recompiles the EARTH executable before starting the run.

• PLANT is included in PHOENICS 1.4 Shareware.
