Burning velocity and the influence of flame stretch [PDF]
, 1991 A new technique is presented for determining burning velocities and stretch effects in laminar flames, and applied to a range of fuel/air mixtures. The speeds of expanding spherical flames, measured by high-speed schlieren cine-photography, are shown to

An Experimental Investigation of Flame Spreading from Bluff Body Flameholders [PDF]
, 1958 Flame spreading from 1/16 to l inch circular cylinder flame holders in two-dimensional flow was studied experimentally. Combustion wake widths were determined by use of spark Schlieren photographs at distances up to 36 inches downstream of the flame ...

Combined effects of width and moisture content on upward flame spread over cotton fabrics
Case Studies in Thermal Engineering, 2019 Present work experimentally investigates the combined effects of width and moisture on the upward flame characteristics over cotton fabrics, using 0.245 mm thick and 1500 mm tall samples with 5 different widths (40 mm, 60 mm, 80 mm, 100 mm, 120 mm) and 5

Multi-Scale Bionic Structure Constructs Biomass Flame-Retardant Thermal Insulation Foam Material. [PDF]
Adv Sci (Weinh)Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...
