Forced convective heat transfer from premixed flames

Heat transfer characteristics of an array of impinging pre-mixed slot flame jets

“…The three flame jets impinged vertically upward onto a water-cooled copper impingement plate having a surface area of 500 · 500 mm 2 and a thickness of 8 mm. The cooling water was kept at a temperature of 38°C by a refrigerator to eliminate the condensation of water vapor on the impingement plate surface [17,18].…”

“…Most of the previous investigations of impinging flame jets are concerned with the single round jet [1, [14][15][16][17][18][19]. However, heat transfer characteristics of the multiple flame jet system are rather different from those of the single jet due to the existence of jet-to-jet interactions, which cannot be identified from the single jet system [8,20].…”

Wok design: thermal-performance influencing parameters

“…Heat transfers from the impingement flame to the food being cooked are by conduction (which is affected by the thermal conductivity of the material of the impingement plate), convection (which depends on the geometry of the impingement plate, as well as the flow and thermal characteristics of the flame), and radiation (which is influenced by the surface emissivity of the impingement plate). Convection is the dominant heat-transfer mechanism from the impinging flame [1][2][3][4][5][6].…”

Convective heat transfer from a partially premixed impinging flame jet. Part I: Time-averaged results

“…Early work by Hargrave et al was among the first to explore the physics of flame structure and corresponding heat transfer for impinging flame jets [5,6]. Relatively recent reviews by Viskanta [1,3,4] and Baukal and Gebhart [2,[7][8][9] summarize the results of studies prior to their publication date, and call attention to areas that have yet to be explored.…”
