Abstract: Combustion of fog consisting of a hydrogen–air mixture, water vapor, and ultrafine particles of water is studied experimentally. Inflammable fog was generated by sudden expansion of a system “hydrogenair + water vapor”. It is shown that partial condensation of vapor with the formation of microdroplets constricts the flammability limits.

Keywords: flammability limits, heterogeneous mixtures, rarefaction wave, IR diagnostics.
