Study on flame cutting process of thick stainless-clad steel

Journal of Physics: Conference Series, 2023
Abstract In general, three different types of processes can be utilized to cut thick stainless-clad steel: waterjet cutting, mechanical cutting, and thermal cutting (plasma, flame, and EDM cutting). Because stainless steel contains a lot of Cr, Ni, and other elements with high ignition and melting temperatures, flame cutting is not ...

Flame fronts in Supernovae Ia and their pulsational stability

, 2013
The structure of the deflagration burning front in type Ia supernovae is considered. The parameters of the flame are obtained: its normal velocity and thickness. The results are in good agreement with the previous works of different authors.

Nonlinear equation for curved stationary flames [PDF]

, 2001
A nonlinear equation describing curved stationary flames with arbitrary gas expansion $\theta = \rho_{{\rm fuel}}/\rho_{{\rm burnt}}$, subject to the Landau-Darrieus instability, is obtained in a closed form without an assumption of weak nonlinearity. It

An engineering model for creeping flame spread over idealized electrical wires in microgravity

Comptes Rendus. Mécanique, 2023
Flame spread over an insulated electrical wire is a major source of fire scenario in a space vehicle. In this work, an engineering model that predicts the creeping flame spread over cylindrical wires in microgravity is developed.

The Thermonuclear Explosion Of Chandrasekhar Mass White Dwarfs [PDF]

, 1996
The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities. We briefly review these instabilities and the corresponding flame acceleration. We discuss the conditions necessary for each of the

Cracking and Failure Characteristics of Flame Cut Thick Steel Plates [PDF]

Metallurgical and Materials Transactions A, 2020
Abstract The manufacturing of thick wear-resistant steel plates commonly leads to a layered structure and non-uniform properties in the thickness direction which makes the processing and utilization of the plates problematic. The processing steps of thick plates include flame cutting, which generates a heat-affected zone and high residual ...

Premixed flame propagation in vertical tubes

, 2015
Analytical treatment of premixed flame propagation in vertical tubes with smooth walls is given. Using the on-shell flame description, equations describing quasi-steady flame with a small but finite front thickness are obtained and solved numerically. It
