Sentence examples for flame spreading rate from inspiring English sources
Results show that the flame spreading rate is mainly controlled by the ambient oxidizer concentration relative to the fuel concentration, modified by the flow rate from the burner, and that the characteristic diffusion length can be significantly larger or smaller than the flame radius, with their ratio being related to the quasisteady assumption.
