摘要：
The spatial structure of a swirling flow in a model vortex furnace with distributed input of fuel-air-mixture jets has been studied. The results of experimental and numerical investigations of a three-dimensional (3D) field of time-averaged velocities in an isothermal laboratory model of a vortex furnace have been used to image the structure of flow. Vortex structures have been identified using lambda(2) and Q criteria, as well as the concept of "minimum total pressure." The vortex core of the flow has a V-shaped 3D structure.
