Substitution of Fog Oil with Diesel Fuel Using a Thermomechanical Approach.

Abstract

The primary objective of this work was to investigate the possibility of improving the quality (yield and persistence) of diesel fuel as a screening smoke by thermomechanical means such as controlling the degrees of superheat in the diesel fuel vapors and the rates of formation of condensation nuclei via nozzle design and mixing with ambient air. A smoke tunnel 42 inches in cross-section and 16 feet long was constructed. The obscuring power of the smoke was quantified by measuring light transmitted by a helium-neon laser light source. Results of the work to date indicate that substantial improvement in the quality of diesel fuel smoke can be achieved by thermomechanical means. Dispersal of a solid such as talc in the diesel smoke also increased obscuration but no dramatically. Keywords: smoke generation; smoke additives; nozzle design; air entrainment.
