Abstract The flame height and lift-off height of the turbulent jet diffusion flame of gas mixture at ambient temperature and pressure were studied. Different diameter nozzles (2, 3 and 4 mm), heat release rates, and concentrations of carbon dioxide (CO2) were considered. The flow rates of propane (C3H8) and CO2 were controlled by two rotameters.

Measurement of Flame Height by Image Processing Method
Advanced Materials Research, 2011 In order to measure the flame height (Lf), the image processing method was employed. The jet flame image was captured by the common-used digital camera. The resolution (C, with the unit of mm/pixel) of the pixel of the digital camera was calibrated by metric scale.

Determining Flame Height And Flame Pulsation Frequency And Estimating Heat Release Rate From 3D Flame Reconstruction [PDF]
, 2005 A method of creating a 3-dimensional point cloud representation of a buoyant diffusion flame from video footage from multiple angles has been created. This point cloud contains probabilities that the flame existed over the period the method was applied. This thesis uses these methods to determine flame height, flame pulsation frequency and flame volume

Experimental study of the effect of ullage height on flame characteristics of pool fires [PDF]
Combustion and Flame, 2020 A series of experiments were carried out to investigate the effect of ullage height, i.e. the distance between fuel surface and the pool upper rim, on flame characteristics of heptane and ethanol pool fires.

Abstract A “chemical” flame height has been defined from the ratio of CO to CO 2 yields, y CO / y CO 2 , and has been shown to be functionally identical with previous results based on flame luminosity. The chemical flame heights have been determined for propane and acetylene data for fire Froude numbers, Q * , ranging from 0.1 to 60,000.
