Grahic Jump Location
Sketch of the test rig (not to scale): I—choked inlet to plenum, P—plenum, C—combustion chamber, X—exit. Flow is from left to right. All dimensions are in mm. The nominal cross-sectional area of the burner is evaluated in the throat of the burner at c.
Grahic Jump Location
Pressure drop characteristic, i.e., difference pP−pC of the mean pressures in plenum and combustor versus air excess ratio λ for power output P=61 kW (–), 75 kW ([[dashed_line]]), 95 kW (+), and 106 kW (⋄). Strong combustion oscillations were observed with P=95 kW for λ<1.26 and with P=106 kW for λ<1.24.

Pressure drop coefficient ζ versus air excess ratio λ for power output P=61 kW (–), 75 kW ([[dashed_line]]), 95 kW (+), and 106 kW (⋄). Strong combustion oscillations were observed with P=95 kW for λ<1.26 and with P=106 kW for λ<1.24.
Grahic Jump Location
Exemplary sketch of a premix combustion system. P—plenum chamber, B—inside burner, cross section with nominal area AB,l—(virtual) length of the burner, f–h—position of flame, C—combustion chamber, X—choked exit. Flow is from left to right.
Grahic Jump Location
Sketch of a pressure loss characteristic with negative slope. If the mass flux increases beyond point X, the mode of flame stabilization changes, pressure drop decreases and the system may become unstable.
