Abstract
The laminar burning velocity is a fundamental property of combustible
mixtures important for kinetic model validation as well as for practical
applications. Many efforts are directed towards its accurate determination.
The heat flux method is one of the commonly recognized methods
for measuring laminar burning velocity, however, the information on the
accuracy of the method is scattered in the literature. In the present work,
an attempt wasmade to summarize and extend the available information
on the different factors contributing to the experimental uncertainty of
the heat flux method. Experimental setup of the Lund University group,

mixtures important for kinetic model validation as well as for practical

The heat flux method is one of the commonly recognized methods
for measuring laminar burning velocity, however, the information on the
accuracy of the method is scattered in the literature. In the present work,
an attempt wasmade to summarize and extend the available information
on the different factors contributing to the experimental uncertainty of
the heat flux method. Experimental setup of the Lund University group,
typical for the heat flux community, and the procedures used to determine
the burning velocity are described. Furthermore, the influence of
different uncertainty factors, originating from each part of the setup, is
analyzed. Asymmetric heat fluxes and the method for determining flame
surface area were found to give an important contribution to the total
error. As a result of this, some of the previously published data have been
re-evaluated. Finally, recommendations are presented on how to control
or reduce the uncertainties in the heat flux measurements, and possible
directions for future research, aimed at improvement of the accuracy and
understanding of the method, are outlined. (Less)
