An SMLD joint PDF model for turbulent non-premixed combustion using the flamelet progress-variable approach

, 2015
This paper provides an improved flamelet/progress variable (FPV) model for the simulation of turbulent combustion, employing the statistically most likely distribution (SMLD) approach for the joint probability density function (PDF) of the mixture ...

Quantitative mapping mechanism between thermo-flow coupled characteristics and cutting performance of oxygen-propane cutting nozzles

Case Studies in Thermal Engineering
The present study is founded upon the theoretical framework of isentropic flow, and it puts forward a structural enhancement, of the Laval type, for the oxygen channel of a commercial straight-tube oxygen-propane cutting nozzle.

Conversational Humor in Intercultural Communication

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This study identifies failed attempts at conversational humor that were either not appreciated or resulted in impoliteness as produced by English as a lingua franca (ELF) users from the Southeast Asian countries of Thailand, Indonesia, and Myanmar who were engaging in intercultural communication.

Large Eddy Simulation (LES) of Hydrogen Jet Flames and Finite Element Analysis of Thermal Barrier Coating

Fluids
A jet flame occurs when the release of flammable gas or liquid ignites, resulting in a long, intense, and highly directional flame. This type of fire is commonly associated with industrial incidents involving pipelines, storage tanks, and other ...

Initiation of the detonation in the gravitationally confined detonation model of Type Ia supernovae

, 2009
We study the initiation of the detonation in the gravitationally confined detonation (GCD) model of Type Ia supernovae (SNe Ia). Initiation of the detonation occurs spontaneously in a region where the length scale of the temperature gradient extending ...
