UDF Data Access Macro
 
Hi,

I am running a DPM model with vaporizing droplets (1 vpaorizing species). I require to access the heat and mass transfer coefficient used by the solver for the vaporization law. does anyone know of the macro that we can use to access them?

Alternatively, if the coefficients can't be accessed, they can be calculated with the following properties:

particle reynolds number viscosity (continuous phase) specific heat capacity (continuous phase) species diffusion coefficient (in the continuous phase) particle to fluid relative velocity prandtl number schmidt number

I tied looking in the UDF manual but can seem to find the macro to access these properties. Hope someone can help. It will be great if we can access the heat and mass transfer coefficients directly.

Woo
