TLDR
In this article, three types of scale-models, with scaling ratios of 1 235, 1 2500, and 1 4837, corresponding to three actual fire whirls (prototypes) were designed in the laboratory.About:

Current approaches to modelling the spread of wildland fire: a review:
TL;DR: Two research areas of great importance if fire modelling techniques are to improve are a better understanding of fire-dependent phenomena and the development of a ‘new generation’ of fire spread models; current trends in these areas of research are evaluated.

Synthesis of knowledge of extreme fire behavior : volume I for fire managers /
Paul Werth,Brian E. Potter,Craig B. Clements,Mark A. Finney,Scott L. Goodrick,Martin E. Alexander,Miguel G. Cruz,Jason A. Forthofer,Sara McAllister +8 more
TL;DR: A summary of existing extreme fire behavior knowledge for use by fire managers, firefighters, and fire researchers can be found in this paper, where the authors focus on the state of the science, but will also consider how that science is currently presented to the fire management community.
Journal ArticleDOI
Scaling fire whirls
TL;DR: In this article, a scaling law that predicts the critical lateral wind velocity was developed and validated by various data including scale-model experiments by other researchers and real urban fire whirls, and a dimensional analysis was conducted to understand the effect of flow circulation on the increase in flame height.
Journal ArticleDOI
Burn-out time data analysis on interaction effects among multiple fires in fire arrays
TL;DR: In this article, an experimental and methodological investigation on the behaviors of square fire arrays which are composed of 3.5 to 7.7 n-heptane fires initiated from fuel pans of 5 cm in diameter and 2 cm in height is presented.

Experimental research on combustion dynamics of medium-scale fire whirl
Jiao Lei,Naian Liu,Linhe Zhang,Haixiang Chen,Lifu Shu,Pu Chen,Zhihua Deng,Jiping Zhu,Kohyu Satoh,John L. de Ris +9 more
TL;DR: The medium-scale fire whirl was extensively investigated by experimental means, in order to establish correlations of the burning rate, flame height and flame temperature of fire WHR, and to clarify the difference between fire WHRs and general pool fires.

A model for the wind-blown flame from a line fire
TL;DR: In this paper, a model for the structure of a wind-blown, turbulent flame from a line fire in which buoyancy is the principal source of vertical momentum is developed, with rate proportional to the strain rate of the mean streamlines of the flame fluid flow.
Journal ArticleDOI
Urban and wildland fire phenomenology
TL;DR: In this paper, the authors present a general treatment of fire as a phenomenon, focusing on the physiological, social, economic, organizational, and operational aspects of fire phenomena, with the objective of bringing together many aspects of Fire Science for a nonspecialized audience.

Intense Atmospheric Vortices Associated with a 1000 MW Fire
TL;DR: In this article, the Meteotron was used to generate a large thermal plume and three types of vortices were observed: large counter-rotating rolls in the downstream plume, small-scale vortice resembling very strong dust devils seen at the surface on the downwind side of the plume.

A Study of Scaling Laws in Pool and Crib Fires
R. I. Emori,Kozo Saito +1 more
TL;DR: In this paper, scaling laws for pool and crib fire experiments were proposed to predict that the burning time and the irradiance measured at geometrically similar points in pool fires will not depend on the size, while those in crib fires will be proportional to the square root of the length.
