Pulsating and hydrodynamic instabilities at large Lewis numbers

Combustion and Flame, 2006
The dynamic behavior of freely propagating premixed flames with large Lewis numbers was computationally simulated using a sixth-order central difference scheme and nonreflective boundary conditions. Results in the linear stage of the instability growth show that the growth rate dramatically decreases with increasing Lewis number and that the large ...

Deriving relations for the Lewis number

Journal of Engineering Physics, 1978
Experimentally confirmed theoretical relations are obtained for the ratio of the coefficients of heat and mass transfer (the Lewis number); an example of air and water in contact is given.

Analysis of Lewis number effects in flame spread

International Journal of Heat and Mass Transfer, 1993
De Ris's formulation of the problem of flame spread over thin and thick solid fuel surfaces is extended to include the influence of nonunity Lewis numbers of oxidant and fuel vapors. A zeroth order formula for the flame spread velocity is deduced. To this order of approximation, the Lewis number of the oxidant affects the spread rate only through its ...

Liquid-fuel burning with nonunitary Lewis number

Combustion and Flame, 2007
An analysis is presented for liquid-fuel vaporization and burning with nonunitary Lewis number (i.e., nonsimilar heat and mass diffusion) in a general geometrical situation, e.g., a dense spray. Variable transport properties are considered and only Stefan flow is allowed.

Streamline segment statistics of premixed flames with nonunity Lewis numbers

Physical Review E, 2014
The interaction of flame and surrounding fluid motion is of central importance in the fundamental understanding of turbulent combustion. It is demonstrated here that this interaction can be represented using streamline segment analysis, which was previously applied in nonreactive turbulence.
