GAS - Gas property specification

GAS gam prl prt gasc

This option allows the user to input different values of γ, laminar and turbulent Prandtl numbers, and gas constant. The parameters are defined as:

    gam   Ratio of specific heats γ = cp/cv (default is 1.4)
prl Laminar Prandtl number (default is 0.72)
prt Turbulent Prandtl number (default is 0.90)
gasc Gas constant R (default is 1716 ft2/sec2-°R)

The ARBITRARY INFLOW keyword block, if used, must come after the GAS keyword in the input data (.dat) file.

There are also a number of VARIABLE TURBULENT PRANDTL number models available for structured grids.
