Novel piperazine-containing oligomer as flame retardant and crystallization induction additive for thermoplastics polyurethane

, 2020
In flame-retarding polymer field, it is very difficult to achieve simultaneous outstanding flame retardancy and excellent mechanical properties, thus causing the serious lack of high-performance flame-retarded polymers.

Flame jet properties of Bunsen-type flames

Combustion and Flame, 2006
The flame jet width and flame jet velocity of the burnt gases of a premixedBunsen-type flame are important parameters to quantify the heat transfer rate ofthese flames.In this paper a simple expression is derived to estimate the resulting flame jetwidth and flame jet velocity of burnt gases of a free flame afterexpansion over the flame front for the ...

Surface-coating engineering for flame retardant flexible polyurethane foams: A critical review

Composites Part B: Engineering, 2019
Flexible polyurethane foams (FPUFs) have been extensively used in furniture, carpet, automobiles, etc., due to their superior thermal insulation, low bulk density and superior chemical resistant properties. Unfortunately, they are extremely ignitable and

Stratified turbulent Bunsen flames: flame surface analysis and flame surface density modelling

Combustion Theory and Modelling, 2012
In this paper it is investigated whether the Flame Surface Density (FSD) model, developed for turbulent premixed combustion, is also applicable to stratified flames. Direct Numerical Simulations (DNS) of turbulent stratified Bunsen flames have been carried out, using the Flamelet Generated Manifold (FGM) reduction method for reaction kinetics.

Non-premixed Flames (Diffusion Flames)

2011
In many combustion processes, the fuel and oxidizer are separated before entering the reaction zone where they mix and burn. The combustion reactions in such cases are called “non-premixed flames,” or traditionally, “diffusion flames” because the transport of fuel and oxidizer into the reaction zone occurs primarily by diffusion.

The Camphor Flame

, 2018
Popular Hinduism is shaped, above all, by worship of a multitude of powerful divine beings--a superabundance indicated by the proverbial total of 330 million gods and goddesses. The fluid relationship between these beings and humans is a central theme of
