Abstract
This paper presents the first approach at studying the flow field in a flameless combustion chamber using PIV. A non-reactive flow test case from literature was chosen for validation of the experimental test bench and measurement technique. Two components of the averaged velocity field in an area of 100x62 mm2 with a resolution of 0.6 mm was acquired by a 12-bit Phantom camera at 1.4 kHz for 2.38 s. Solid seeding particles of Silicium dioxide SiO2 were used with a 527 nm high-repetition laser. Important characteristics of the flow field in the flameless combustion chamber as the recirculation zone and velocity magnitudes were observed. The result obtained using PIV shows good agreement with a CFD simulation.
