In this work, attenuating unsteady heat-driven thermoacoustic oscillations in a T-shaped standing-wave Rijke-type combustor is numerically and experimentally studied. For this, 2D numerical studies are conducted first on a T-shaped standing-wave combustor. In such combustor, a heater with constant s...
