The generation of external (window) flame due to a compartment fire depends on the behavior of the compartment fire. For clarifying the effects of ventilation opening and conditions of fuel on fires behavior in enclosure, small scale model fire tests were conducted using methanol, PMMA, and wood as the fuels. The external flames were observed for different fuel conditions and ventilation parameter AH^<1/2> whether they are generated or not. And the burning rate, temperature, and heat release rate in enclosure were measured. As the results of this study, it is found that the maximum burning rate under ventilation control regime agree with Kawagoe's results (m_<pk>=0.1AH^<1/2>(kg/s)) regardless the fuel type. And where AH^<1/2> is small, the criteria can be established using stoichiometric air/fuel ratio and ventilation parameter AH^<1/2> for judging whether external flames are generated.
