ABSTRACT
An empirical correlation between quenching distance, qd, and initial pressure, p0, has been used to estimate the model parameters for the butane-air mixture through linear regression. The tests of significance of the two models for qd = qd(p0) dependence for several data sets obtained at different insulating disk diameters and close to stoichiometric compositions of butane in air have been made. The results were further analysed in view to evaluating the performance of the experimental technique.
