The cooling time of white dwarfs produced from type Ia supernovae

, 2010
Type Ia supernovae (SNe Ia) play a key role in measuring cosmological parameters, in which the Phillips relation is adopted. However, the origin of the relation is still unclear. Several parameters are suggested, e.g.

Ignition Time Delay In Swirling Supersonic Flow Combustion

, 2012
Supersonic hydrogen-air cylindrical mixing layer is numerically analyzed to investigate the effect of inlet swirl on ignition time delay in scramjets. Combustion is treated using detail chemical kinetics. One-equation turbulence model of Spalart and Allmaras is chosen to study the problem and advection upstream splitting method is used as computational

NH 3 Ignition Delay Time at Knock engine conditions

, 2023
Several countries, consortia and industries are increasingly publicizing in the press their willingness to consider ammonia as one of the zero carbon footprint fuels of the future. In the case of internal combustion engines, it was previously concluded that the ammonia as fuel can be used alone if boosted operating conditions or high compression ratio [

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Deriving the Charring Rate of a Wood Fibre Insulation Board by Exposure to the ISO 834 Standard Fire

Fire and Materials, EarlyView.
ABSTRACT Wood fibre insulation boards (WFIB) are widely used combustible building materials, commonly applied in energy‐efficient construction for their thermal and hygric performance. The present study investigates the behaviour of the most common type of wood fibre insulation when exposed to the ISO 834 standard fire.

Theoretical kinetic computations in complex reacting systems [PDF]

Nasa Lewis' studies of complex reacting systems at high temperature are discussed. The changes which occur are the result of many different chemical reactions occurring at the same time. Both an experimental and a theoretical approach are needed to fully

IGNITION DELAY TIME INVESTIGATION OF GTL FUEL BLENDS

, 2022
Ignition delay is a vital combustion characteristic of any fuel that directly affects the development of internal combustion engines (ICEs) and exhaust emissions, especially in diesel engines. Considering the global interest in alternative fuels, GTL (Gas to Liquid) can be considered one of the promising new alternative fuels, especially for ...
