An automated thermophoretic soot sampling device for laboratory-scale high-pressure flames.
Studying soot particle morphology in high-pressure flames via thermophoretic sampling critically depends on sampling precision, speed, and reproducibility. This is mainly limited by the challenges of applying pneumatically driven devices for burner chamber pressures higher than the pneumatic pressure. We present a pneumatically driven device for high-pressure applications up to 90 bars. The novelty is to separate the pneumatic driver section from the high-pressure environment in the burner chamber. The device was tested by sampling soot from a laminar high-pressure flame at 20 bars.
