Heat release rate markers for premixed combustion [PDF]

open access: yesCombustion and Flame, 2014
The validity of the commonly used flame marker for heat release rate (HRR) visualization, namely the rate of the reaction OH+CH2O↔HCO+H2O is re-examined. This is done both for methane-air and multi-component fuel-air mixtures for lean and stoichiometric conditions.

Influence and Mechanism Research of Hydration Heat Inhibitor on Low-Heat Portland Cement

open access: yesFrontiers in Materials, 2021
A kind of microcapsule sustained-release–type hydration heat inhibitor (MSR) was prepared. The effect of MSR on semi-adiabatic temperature rise, setting time, and strength of low-heat Portland cement was investigated.

A study on heat release rate indicator in the auto-igniting droplets using direct numerical simulation

open access: yesJournal of Thermal Science and Technology, 2016
Local heat release rate is one of the most concerned parameters in the combustion processes. However, this parameter is hard to be measured directly in the experiments. Therefore local heat release rate indicators have been sought and evaluated, and many
