A correction method for the effect of flame wander was developed to obtain velocity profiles corresponding to the characteristics of the instantaneous whirl. The magnitudes of the corrected radial velocity are zero to within experimental error. The whirl consists of an inner vortex core and an outer free vortex and the tangential velocity fits well with the model of a Burgers vortex. The profile of axial velocity follows a Gaussian distribution and the maximum axial velocity appears at the flame center. Moreover, at the vortex core radius, the axial velocity is 0.3 times the maximum axial velocity in the same level. 1 Fire Technology 52 ARTICULO Wang, Pengfei 43837 Liu, Naian 54840 Hartl, Katherine 55483 Smits, Alexander 55484 189657 189657 0 0 0 0 257476 BAAB BAAB 2026-03-06 200061897 0 200061897 2026-03-06 00:19:49 2026-03-06 ARTICULO
