Laminar burning velocity of hybrid methane‐iron air flames
, 2022 As widely acknowledged, it is mandatory to decarbonize our energy system. A low-cost opportunity to achieve this is with high energy density metal carriers. Renewable energy can be used to reduce metal oxides to metal. This metal can be stored under ambient conditions in the form of a powder and be combusted (=oxidised) whenever energy is needed ...

The temperature dependence of Laminar burning velocities of methanol-syngas-air flames [PDF]
, 2016 Using the simplest alcohol – methanol – as a fuel for spark ignition (SI) engines, enables an increase of thermal efficiency compared to gasoline. Additionally, with the enrichment of hydrogen rich gas from methanol reforming (syngas) using exhaust heat,

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

STUDY OF THE EFFECT OF ELEVATED TEMPERATURES ON THE LAMINAR BURNING VELOCITY OF PROPANE-AIR MIXTURES
Diyala Journal of Engineering Sciences, 2015 Laminar burning velocities were obtained at wide equivalence ratios of propane –air mixtures. The effect of elevated temperatures was also analyzed. It was found that the laminar burning velocity is increased with the increase of temperature at constant

, 2003 We present a numerical investigation of the cellular burning regime in Type Ia supernova explosions. This regime holds at small scales (i.e. below the Gibson scale), which are unresolved in large-scale Type Ia supernova simulations.

On the Evolution of Thermonuclear Flames on Large Scales [PDF]
, 2006 The thermonuclear explosion of a massive white dwarf in a Type Ia supernova explosion is characterized by vastly disparate spatial and temporal scales. The extreme dynamic range inherent to the problem prevents the use of direct numerical simulation and ...

Energy Science &Engineering, EarlyView.Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.
