我的理解是
Advection Scheme 是动量方程对流项的离散格式 Turbulence Numerics 是湍流输运方程对流项的离散格式See "15.5.5. Advection Scheme for Turbulence Equations"
Irrespective of the Advection Scheme setting, the advection scheme for the turbulence model equations depends on the Turbulence Numerics option: ...
Note that Turbulence Numerics option also specifies the transient scheme for the turbulence model equations (see Turbulence Numerics in the CFX-Pre User's Guide). This can be overridden in CFX-Pre in the Solver Control details view on the Equation Class Settings tab.
