Unsteady heat transfer during the interaction of a laminar flame with a cold wall
Measurements were made of the unsteady heat transfer to a wall during the quenching of premixed, methane-air flames. One-dimensional laminar flames were produced in a constant volume chamber and the heat transfer was measured into the quenching surface by means of a platinum thin film resistance thermometer. The experiments were performed over a range of pressures varying from 1 to 4 atmospheres and over a range of equivalence ratios from 0.7 to 1.2. Possible catalytic effects of the gauge were appraised by comparing the heat flux as obtained from different types of gauges. The experimental results were compared to the predictions of three numerical models. Two of the models were finite difference formulation of the conservation equations: one with detailed kinetics and the other with one step kinetics. The third model was an integral method with ignition temperature kinetics.
