Effects of Obstacles on the Passage of Filtering Combustion Waves along a Porous Titanium Tape

Combustion, Explosion, and Shock Waves Aims and scope

Abstract

This paper describes the combustion of tapes in air, rolled from titanium powder, and the delay time of the combustion front motion in the presence of a one-sided obstacle, which limits the access of an oxidizer to the surface. It is shown that the combustion front is aligned with respect to the tape thickness at a long distance from the obstacle, which is two orders of magnitude larger than its thickness. The critical width of the two-sided obstacle is determined. The largest portion of the tape, where the front is aligned with respect to the tape thickness with the one-sided obstacle, and the small critical width of the two-sided obstacle are due to the surface combustion.
