There are two ways to control thermal conductivity in ANSWER. To start with the thermal conductivity is computed from the effective viscosity and the Prandtl number of the fluid; that is: where the fluid viscosity and Prandtl number can be set by the VISCOsity and PRANdtl number commands. The value of thermal conductivity computed above is overwritten by the values specified by the CONDuctivity command if any such command is specified. Examples are: CONDuctivity for H is 0.0034 Or: CONDuctivity for H is a LINEAR function: 0.0034 + 0.001 * T Please see the VISCOSITY, PRANDTL and CONDUCTIVITY commands for further elaboration and other available options. See problem T.052 in ANSWER Examples.
