Hi,
Do anyone know how to add a custom (Chemical as well as physical properties, such as, viscosity, density, ratio of solution, etc.) fluid type in ANSYS?
Go to the FLUENT material database and click add -> new materials and provide all the details. Then you can use the material when defining the particular portion of your domain. Physical properties of fluids and solids are associated with named materials. These materials are then assigned as boundary conditions for zones.
When you model species transport you need to define a mixture material, consisting of the various species involved in the problem. Properties will be defined for the mixture, as well as for the constituent species, which are fluid materials.
For example :-
These files can be created in a text editor and saved with a .scm extension.
(New
fluid
(chemical-formula ....)
(density (constant ....[like for air 1.225])
(premixed-combustion 1.225 300))
(specific-heat (constant . 1006.43))
(thermal-conductivity (constant . 0.0242))
(viscosity (constant . 1.7894e-05)
(sutherland 1.7894e-05 273.11 110.56)
(power-law 1.7894e-05 273.11 0.666))
(molecular-weight (constant . 28.966))
)
(New
solid
(chemical-formula ....[suppose as al ])
(density (constant . 2719))
(specific-heat (constant . 871))
(thermal-conductivity (constant . 202.4))
(formation-entropy (constant . 164448.08))
)
You can also follow video tutorials on YouTube, and instructions are available in the ANSYS FLUENT user manual.
Kira Haller Ahmed Fouad Thanks a lot for reply. I will try and ask again if needed.
