abstract = "Tubular flames represent a canonical combustion configuration that
can simplify reacting flow analysis and also be employed in
practical power generation systems. In this paper, a theoretical
model for non-premixed tubular flames, with delivery of liquid
fuel through porous walls into a swirling flow field, is
presented. Perturbation theory is used to analyse this new tubular
flame configuration, which is the non-premixed equivalent to a
premixed swirl-type tubular burner following the original
classification of premixed tubular systems into swirl and
counterflow types. The incompressible viscous flow field is
modelled with an axisymmetric similarity solution. Axial decay of
the initial swirl velocity and surface mass transfer from the
porous walls are considered through the superposition of laminar
swirling flow on a Berman flow with uniform mass injection in a
straight pipe. The flame structure is obtained assuming infinitely
fast conversion of reactants into products and unity Lewis
numbers, allowing the application of the ShvabZeldovich coupling
function approach.",
