Uncertainty in stretch extrapolation of laminar flame speed from expanding spherical flames
Proceedings of the Combustion Institute, 2015 Abstract The present work investigated the uncertainties associated with the extrapolation of stretched flames to zero stretch in flame speed measurements using expanding spherical flames. Direct numerical simulations of time evolution of expanding spherical flames from a small ignition kernel to a propagating front with sufficiently large radius ...

Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects
High Voltage, EarlyView.ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Laser induced spark ignition of methane-oxygen mixtures [PDF]
Results from an experimental study of laser induced spark ignition of methane-oxygen mixtures are presented. The experiments were conducted at atmospheric pressure and 296 K under laminar pre-mixed and turbulent-incompletely mixed conditions.

Triple flame structure and diffusion flame stabilization [PDF]
, 1994 The stabilization of diffusion ñames is studied using asymptotic techniques and numerical tools. The configuration studied corresponda to parallel streams of cold oxidizer and fuel initially separated by a splitter píate.

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Premixed CH-Air Flame Structure Characteristic and Flow Behavior Induced by Obstacle in an Open Duct
Advances in Mechanical Engineering, 2015 To study the fuel gas combustion hazards, the methane/air flame structure and flow characteristic in an open duct influenced by a rectangular obstacle were explored by experiment and realizable k -∊ model (RKE).

A Level Set Approach for a Premixed Flame Based on a New Concept of Flame Speed
Journal of Thermal Science and Technology, 2011 In this paper we propose a new level set approach to describe not only a flame's surface but also to the flame's spatial distribution. First, we derived the mathematical formulation for a one-dimensional laminar premixed flame, where the steady
