摘要: In the present work non-idealities of flat burner-stabilized flames at atmospheric and low pressures are examined using PIV measurements, which supported by analyzed with help CFD modeling. Radial axial velocity profiles measured in cold flow lower presented. Two possible reasons for drop apparent laminar burning (below 20 kPa) were considered: non-uniformity profile issuing from burner mouth diffusion gas mixture original flow. At very an outward edge plate is detected. A part fuel–air therefore seems to escape burner. Further experiments, however, revealed that fuel fresh ambient atmosphere into flame less important as compared diffusive loss H atoms pressures. This was substantiated numerical analysis assessment earlier observations literature. critical relation between size lowest pressure ensuring stabilization a demonstrated.
