hello , I would like to know if somebody already entered fluid properties for hydrocarbon vapors in “MY MATERIALS”, in gas phase . Thanks, I am wondering what is the As constant , here the table I mean for air as a reference . Thanks !
(R) Gas constant 287.1 J/(kg·K)
As 1.46e-6 kg/(m·s·K^(1/2))
(Cp) Specific heat at constant pressure 1004 J/(kg·K)
(Cv) Specific heat at constant volume 717 J/(kg·K)
(Hf) Heat of formation 0 J/kg
(Pr) Laminar Prandtl number 0.713
(Sf) Standard entropy 6990 J/(kg·K)
(T0) Reference temperature 273.1 K
(Sμ) Sutherland constant 110.4 K
(μ) Dynamic viscosity 1.83e-5 kg/(s·m)
(Prt) Turbulent Prandtl number 0.85
(μ0) Reference viscosity 1.716e-5 kg/(s·m)
(β) Expansion coefficient 3.43e-3 1/K
(ρ) Density 1.196 kg/m³
Fluid type GAS
(M) Molar mass 28.97 kg/kmol
(μ) Kinematic viscosity 1.529e-5 m²/s
(c) Speed of sound 343.6 m/s
Electric conductivity 0 S/m

Hi there,
Thank you for posting on the forum!
May I ask where did you get these values? Are these the properties of Air as pre-defined in the library?
yes, this for air in the data base, thanks for helping if you can
There is a big revamp of custom materials underway, we will keep you updated about it.
Do you wish to define a custom material? We can then get in touch with you regarding this
