## What is/are Rectangular Source?

Rectangular Source - ABSTRACT An experimental study is conducted to reveal the flame‒flame interaction (including completely continuous merging phenomenon, intermittent merging phenomenon, and non-merging phenomenon) of and the merging flame length of double propane diffusion flame with various aspect ratios, and its influence is measured in terms of the fire heat release rates, separate spaces between rectangular sources and different pool aspect ratios (1:1, 1:2, 1:4, and 1:8).^{[1]}New correlations for flame height, width and thickness of the wall attached flames are proposed based on the mirror-approach of the rectangular source relative to that of a free flame, where the burner perimeter is found to be an appropriate length scale.

^{[2]}The response of a TiN/TaOx/TiN S-type threshold switching device to a rectangular source voltage pulse was simulated using an electrothermal finite element model.

^{[3]}Flame heights of buoyancy-controlled diffusion plumes generated by a rectangular source fire were investigated.

^{[4]}Flame height and lift-off distance of vertically oriented rectangular source natural gas jet fires with buoyancy-momentum flame Froude number up to 3.
