Studies of flame and combustion processes on earth are
frequently complicated by the inevitable presence of buoyancy,
which not only quantitatively affects the combustion rate but can
also severely distort the flame configuration from some degree of
symmetry needed for fundamental understanding of the flame
structure. In this project we study the structure of perfectly
cylindrical and spherical flames obtainable only in the
microgravity environments of drop towers, parabolic flights, and
space stations.
