Generalization of Oberlack’s definition of the MILD combustion regime

Fuel
The Oberlack definition of the MILD combustion limit for premixed systems was derived under the assumption of lean combustion and a one-step reaction. In this study, a generalization of this definition is presented by removing the lean combustion assumption, which leads to a more comprehensive relation between the Damköhler number and temperature ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...

The effect of combustion sub-grid closures in LES of MILD combustion

, 2019
In Moderate or Intense Low oxygen Dilution (MILD) combustion regime, the system evolves towards a distributed reaction regime and low temperatures, which leads to higher chemical and lower mixing time scales. Thus, the characteristic Damk¨ohler number has the order of 1. As a result, models accounting for finite rate chemistry should be considered.
