Y.; Edelman, Raymond B.; Stocker, Dennis P.; Sotos, Raymond G.; Vaughan, David F. Abstract: Laminar diffusion flames of methane, burning in quiescent oxidizing environments at atmospheric pressure, have been studied under both normal-gravity and microgravity conditions. Radiation from these flames is measured using ...
