“…Therefore, the body of the gauge would be assumed as thermally semi-infinite and the heat flux density can be reconstructed from the front surface temperature time evolution by solving a one-dimensional heat transfer problem. The following relationship has been used to calculate wall heat flux q (Heperkan and Greif, 1982):…”

Ecole Nationale Supé rieure de Mé canique et d'Aé rotechnique, Futuroscope Chasseneuil Cedex, FranceThis work presents results of quenching distance and heat flux measurements during the head-on quenching of transient laminar stoichiometric methane=air flame in the pressure range 0.05-1.7 MPa. The results of direct visualization have been used to measure the quenching distance and to prove the relationship relating the quenching distance and heat flux to the wall over the global combustion reaction rate. It is shown that quenching distance decreases from 0.43 to 0.016 mm with pressure rise from 0.05 to 1.7 MPa. The maximum wall heat flux increases nonlinearly from 0.35 to 2.3 MW=m 2 with pressure rise from 0.05 to 1.7 MPa. The dimensionless value of the heat flux depends only slightly on the pressure and decreases from 0.3 to 0.2 with rise of pressure in this pressure range. Flame-wall interaction time is about constant and equal to 0.15-0.155 ms in all ranges of pressure variation.

“…Especially prominent in this field are the multifarious publications of Woschni [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Of particular significance to our studies were the contributions of Greif and his associates [20][21][22][23][24][25][26]. The self-similarity theory reported here was developed on their basis, allowing the energy lost by heat transfer to the walls in the course of combustion to be evaluated from a measured pressure record.…”
