    HAM: computer models

    Division: engineering and research HAM models HAM assumption for multiphase flow moisture transport

    engineering model: "relates moisture flux to the gradient of moisture content and in doing so utilizes secondary moisture characteristics (moisture diffusivity)". For design. example HAM: WUFI-ORNL/IBP, HAM: WUFI (W?rme- Und Feuchtetransport Instation?r)

    research model: "uses the gradient of moisture potentials and primary transport coefficients (moisture conductivity)", for research. attempts: HAM: hygIRC, HAM: MOISTURE-EXPERT

    The computer codes for heat, air and moisture transport in building envelopes. The survey by Hens, H. and Janssens, A., 1993, Inquiry on HAMCAT codes is the most complete and classic review on the issue.
