Temporal Evolution of Soot Particles from C2H2/O2 Combustion in a Closed Chamber

Abstract: 0.75 ou de C2H2/O2/Ar com razão C/O = 1.00 é de cerca de 3.0-4.0 ms, após o início da reação. O máximo de emissão dos radicais excitados e o máximo da pressão nestas reações, ocorrem praticamente neste mesmo intervalo de tempo. Observou-se a formação de partículas de fuligem compactas e aproximadamente esféricas com 60-150 nm de diâmetro. Entretanto, os agregados não são compactos e mostram uma estrutura de rede que se assemelha a de um aerogel.]]>
