The Structure of Medium-Scale Pool Fires

January 5, 2022
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Kimberly Harris, Anthony Hamins
This report documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, acetone, methane, and propane pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a

The structure of medium-scale propane pool fires

September 23, 2021
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Anthony Hamins
A series of time-averaged temperature, velocity, and gas species measurements are made along the centerline of propane fires established on a 37 cm diameter gas burner situated in a quiescent environment. Fires with heat release rates of 20 kW and 34 kW

Velocity and Temperature Structure of Medium-Scale Pool Fires

June 22, 2021
Author(s)
Kunhyuk Sung, Ryan Falkenstein-Smith, Anthony Hamins
A series of measurements was conducted using a bidirectional probe to characterize the upward speed in the plumes of medium-scale pool fires burning a variety of gaseous and liquid fuels. Time-averaged local measurements of the upward velocity were

The Thermal Character of a 1 m Methanol Pool Fire

June 15, 2021
Author(s)
Kunhyuk Sung, Jian Chen, Matthew Bundy, Marco G. Fernandez, Anthony Hamins
This is the second edition of this study, which presents a series of measurements conducted to characterize the structure of a 1 m diameter methanol pool fire steadily burning with a constant lip height in a well-ventilated quiescent environment. The main

The Evolving Temperature Field in a 1 m Methanol Pool Fire

June 4, 2021
Author(s)
Jian Chen, Kunhyuk Sung, Zhigang Wang, Andy Tam, Ki Yong Lee, Anthony Hamins
Thin filament pyrometry is used to measure the time-varying temperature field in a 1 m methanol pool fire. A digital camera with optical filters and zoom lens recorded the emission intensity of an array of 12 µm Silicon-Carbide filaments oriented

Mixture Fraction Analysis of Combustion Products in Medium-Scale Pool Fires

November 13, 2020
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Anthony Hamins
A mixture fraction analysis is performed to investigate the characteristics of time-averaged gaseous species measurements made along the centerline of medium-scale pool fires steadily burning in a quiescent environment. A series of fire experiments are

Chemical Structure of Medium-Scale Liquid Pool Fires

May 14, 2020
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Anthony Hamins
This work documents a series of time-averaged local gas species measurements made throughout the centerline profile of 30 cm methanol, ethanol, and acetone pool fires steadily burning in a quiescent environment. All gas species measurements were obtained

The Characteristics of a 1 m Methanol Pool Fire

May 4, 2020
Author(s)
Kunhyuk Sung, Jian Chen, Matthew Bundy, Anthony Hamins
A series of measurements was made to characterize the structure of a 1 m diameter methyl 12 alcohol (methanol; CH3OH) pool fire steadily burning with a constant lip height in a quiescent 13 environment. Time-averaged local measurements of gas-phase

The Chemical Structure of a 30 cm Methanol Pool Fire

April 25, 2020
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Anthony Hamins
This study documents a series of time-averaged gas species measurements made along the centerline of a 30 cm methanol pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a Gas Chromatograph/ Mass

The Thermal Character of a 1 m Methanol Pool Fire
