Bao, H. (author), Huang, X. (author), Roekaerts, D.J.E.M. (author)The Delft Jet-in Hot Coflow (DJHC) burner is used to investigate flameless combustion by imitating the recirculation flow characteristics appearing in a real complex furnace via a hot diluted coflow[1]. A welldefined stream of high temperature, low oxygen concentration combustion products is injected around the...abstract 2016

Huang, X. (author), Tummers, M.J. (author), Roekaerts, D.J.E.M. (author)Flameless combustion, named as Moderate or Intense Low-oxygen Dilution (MILD) combustion or high-temperature air combustion (HiTAC), is a promising technology to improve the thermal efficiency while suppressing NOx formation in combustion systems. Flameless combustion can occur when fresh air (and/or fuel)...abstract 2017

(author)We report on a comparative study of model predictions of jet-in-hot-coflow flames. TheDelft Jet-in-Hot- Coflow (DJHC) burner was built to mimic the important characteristics of flameless combustion without the complications of a real furnace [1,2]. The DJHC burner has been used to create a turbulent diffusion...abstract 2016

Huang, X. (author), Tummers, M.J. (author), Roekaerts, D.J.E.M. (author)Mild combustion in a lab-scale furnace has been experimentally and numerically studied. The furnace was operated with Dutch natural gas (DNG) at 10 kW and at an equivalence ratio of 0.8. OH∗chemiluminescence images were taken to characterize the reaction zone. The chemiluminescence intensity is relatively low compared to conventional flames...abstract 2016

De, Ashoke (author), Sarras, G. (author), Roekaerts, D.J.E.M. (author)A probability density function (PDF)-based combustion modeling approach for RANS simulation of a jet issuing into a hot and diluted coflow is performed. A tabulated chemistry-based model, i.e., flamelet-generated manifold (FGM), is adopted in the PDF method. The manifolds are constructed using igniting counterflow diffusion flamelets with...book chapter 2021

Fathi, Mohamad (author), Hickel, S. (author), Roekaerts, D.J.E.M. (author)Transcritical fuel sprays form an indispensable part of high-pressure energy-conversion systems. Modeling the complex real-fluid effects in the high-pressure multiphase regime of such sprays accurately, especially the hybrid subcritical-to-supercritical mode of evaporation during mixing fuel and oxidizer, is essential and challenging. This...book chapter 2023

Ma, L. (author), Naud, B. (author), Roekaerts, D.J.E.M. (author)MILD Combustion, also known as flameless combustion, is attracting wide scientific interest due to its potential of high efficiency and low NOx emission. This paper focuses on the numerical modeling of one of the ethanol spray flame cases from the Delft Spray-in-Hot-Coflow (DSHC) burner, which has been used to study MILD oxidation of liquid...conference paper 2014
