...Jianhua Zhou; Yuwen Zhang; J. K. Chen; Z. C. Feng The inverse heat conduction problem (IHCP) in a one-dimensional composite slab with rate-dependent pyrolysis chemical reaction and outgassing flow effects is investigated using the iterative regularization approach. The thermal properties...

...: rate-dependent pyrolysis, pyrolysis by-product outgassing, irradiance-dependent convection heat loss, and radiation heat lose. Both the shape of the gas flow channel and the gas addition velocity from the channel wall are evaluated based on the decomposition reaction rate. The through-thickness...
