Scalar conductivity
 

HELLO!!

I have a quenstion in "common file".What is the "scalar conductivity "meaning??And its physical meaning??? Can anybody answer me?? Thanks in advanced

Re: Scalar conductivity
 

I'm guessing you are using CFX-4 and speaking about the "command file" which contains the CFX-4 commands language......

The scalar conductivity is simply the thermal conductivity of the fluid. It's "scalar" because it is isotropic. This means the conductivity is the same in all directions.

Hello Jeff :

Thanks for your message!!! But when I change parameter in my common file¡AI also saw the "thermal conductivity" of HEAT TRANSFER PARAMETERS¡CIf you say that the "scalar conductivity" is the thermal conductivity of the fluid¡Awhat is the thermal conductivity meaning¡Aand what are different between them??Anyway thanks for your response¡Aand like below is part of my common file :

>>PHYSICAL PROPERTIES

>>FLUID PARAMETERS

VISCOSITY 1.0000E+00

DENSITY 1.0000E+00

>>HEAT TRANSFER PARAMETERS

THERMAL CONDUCTIVITY 2.000E+01

FLUID SPECIFIC HEAT 1.0000E+00

ENTHALPY REFERENCE TEMPERATURE 2.9800E+02

>>SOLID HEAT TRANSFER PARAMETERS

PATCH GROUP NUMBER 1

SPECIFIC HEAT 4.400E+02

DENSITY 7.8500E+03

SCALAR CONDUCTIVITY 1.0000E+00

SOLID TEMPERATURE 2.98000E+02

Sorry. Same definition, but for your solid region. I didn't know your problem involved heat transfer solids.
