Thermal conductivity lam(d,T,p) (industrial use version) only in one-phase region
function cond_dTp extends Modelica.Icons.Function; input SI.Density d "density"; input SI.Temperature T "temperature (K)"; input SI.Pressure p "pressure"; input Integer phase = 0 "2 for two-phase, 1 for one-phase, 0 if not known"; input Boolean industrialMethod = true "if true, the industrial method is used, otherwise the scientific one"; output SI.ThermalConductivity lambda "thermal conductivity"; end cond_dTp;
