TLDR
In this article, a detailed description of double burner fire whirls is given, where two burners are placed symmetrically about the center of a fixed frame, and the flame from each burner sweeps along the ground until it reaches the point midway between the burners.About:

TL;DR: In this paper , a self-sustained iron flame can be established inside the MC2 under normal air conditions, and even at very low oxygen concentrations (∼ 10% O2) and for low overall equivalence ratios ( ∼ 0.2), without any assisting extra heat sources.

Temperature, velocity and air entrainment of fire whirl plume: A comprehensive experimental investigation
TL;DR: In this article, the authors examined the air entrainment of propane fire whirl plume in a medium-scale fixed-frame facility and found that the radial profile of excess temperature varies consistently with the continuous flame shape and the radial decay rate decreases in the intermittent flame and plume.

Effect of flow circulation on combustion dynamics of fire whirl
TL;DR: In this paper, the effect of flow circulation on the combustion dynamics of fire whirl is systematically investigated by experiments, and new correlations for the burning rate, flame height, radial temperature and mass flow rate are established.

Scaling of a small scale burner fire whirl
Katherine Hartl,Alexander Smits +1 more
TL;DR: In this paper, the behavior of a fire whirl generated using a burner is examined using Particle Image Velocimetry (PIV) using two staggered cylinder halves that surround the burner.

Flow Structure Of A Fixed-frame Type Firewhirl
TL;DR: In this article, a fixed-frame type fire whirl generator consisting of two vertically oriented split PMMA cylinders was designed to create a small compartment with a slit at each end, at the center of which a 5 cm-diameter 1-propanol pool fire generated upward buoyancy flow and fresh air entering the compartment through the slits, generating swirl motion in the compartment.
