Predicts product temperature at the sublimation interface based on pseudo steady-state heat and mass transfer model

* Fill volume Solids concentration

* Shelf heat transfer coefficient

* Cross sectional area of the product in the vial

* Vial area calculated based on outside diameter

* Dry layer mass transfer resistance parameters: Rphat=R0+A1*l/(1+A2*l), where l is thiskness of dry layer at any time

* Shelf temperature

* Chamber pressure


OUTPUT: Temperature versus time; Drying rate vs time
