AbstractThe simplified model for postflashover buning of thermoplastic materials proposed by Yung [I] provides a simple tool for conservative modeling of postflashover fire behavior. Yung's analysis. through similarity considerations, of the equations governing postflash over fires results in two algebraic equations that depend on six similarity parameters and three coefficients. The complexity of one of the equationsrequires a numerical procedure to be employed. This was accomplised by creating a computer program in Visual Basic in which the incremental search method is used to determine the root of the equation. Solving this, the conservative values for the gas temperature and burning rate can then be calculated. Values generated by the computer model are shown to be in good agreement with values presented in Ref. 1. As an example, calculated values for the gas temperature, internal and external heat release rates aretabulated and plotted for the burning of flexible polyurethane foams.
