Modelling Heat and Mass Transfer in Wood-frame Floor

A two-dimensional heat and mass transfer finite-element model has been developed in order to more precisely predict the response of a wood-frame floor assembly exposed to fire. The heat and mass transfer analyses are coupled since the mass transfer contributes to heat transfer and the heat transfer is what ultimately drives the mass transfer.
