About us
With about 20 scientific employees and students, the Institute for Combustion Technology of the University of Stuttgart conducts research on the fundamentals of modelling and simulation of turbulent, reacting flows in the areas of gas phase combustion, multiphase flows (gaseous/liquid and gaseous/solid) and nanoparticle processes. The teaching of ITV covers the fundamentals and advanced topics in combustion technology and simulation of reacting flow systems, as well as related programming basics.
Please note that there will be no consultation hours at the institute until further notice!
The office will be staffed sporadically on site, but one can contact the office via email.
In general, all staff can be contacted via email.
We offer to the students the opportunity to take part in the upcoming presentations of the study- and master theses at ITV and to receive proof of this (form "seminar lectures").
The presentations are for the time being only "virtual", so you can join via Webex.
The link to the respective talk will be shown here on the presentation date at the latest.
Please write an email to the Administrator (see below) if you want to attend and need a proof!

Modeling of Sub-Grid Conditional Mixing Statistics in Turbulent Sprays Using Machine Learning Methods
Authors: S. Yao, B. Wang, A. Kronenburg and O. T. Stein
Deep artificial neural networks (ANNs) are used for the modeling of the sub-grid scale mixing quantities such as the filtered density function (FDF) of mixture fraction and the conditional scalar dissipation rate. A deep ANN with four hidden layers is trained with carrier-phase direct numerical simulations (CP-DNS) of turbulent spray combustion. [see more]
Carrier-phase DNS of detailed NOx formation in early-stage pulverized coal combustion with fuel-bound nitrogen
Authors: A. Shamooni, P. Debiagi, B. Wang, T. D. Luu, O. T. Stein, A. Kronenburg, G. Bagheri, A. Stagni, A. Frassoldati, T. Faravelli, A. M. Kempf, X. Wen and C. Hasse
Carrier-phase direct numerical simulation of detailed NOx formation in pulverized coal flames (PCC) with fuel-bound nitrogen is conducted in a 3D temporally evolving mixing layer setup where Lagrangian particles (Colombian bituminous coal) in an air stream (upper half of the domain) mix with the products of lean volatile/ air combustion in the lower stream.

Sparse-Lagrangian PDF Modelling of Silica Synthesis from Silane Jets in Vitiated Co-flows with Varying Inflow Conditions
Authors: G. Neuber, A. Kronenburg, O. T. Stein, C. E. Garcia, B. A. O. Williams, F. Beyrau and M. J. Cleary
This paper presents a comparison of experimental and numerical results for a series of turbulent reacting jets where silica nanoparticles are formed and grow due to surface growth and agglomeration. We use large-eddy simulation coupled with a multiple mapping conditioning approach for the solution of the transport equation for the joint probability density function of scalar composition and particulate size distribution. [see more]
Mixing Time Scale Models for Multiple Mapping Conditioning with Two Reference Variables
Authors: C. Straub, A. Kronenburg, O. T. Stein, S. Galindo-Lopez and M. J. Cleary
A novel multiple mapping conditioning (MMC) approach has been developed for the modelling of turbulent premixed flames including mixture inhomogeneities due to mixture stratification or mixing with the cold surroundings. MMC requires conditioning of a mixing operator on characteristic quantities (reference variables) to ensure localness of mixing in composition space. Previous MMC used the LES-filtered reaction progress variable as reference field. [see more]
Numerical Investigation of Spray Collapse in GDI with OpenFOAM
Authors: J.W. Gärtner, Y. Feng, A. Kronenburg and O. T. Stein
During certain operating conditions in spark-ignited direct injection engines (GDI), the injected fuel will be superheated and begin to rapidly vaporize. Fast vaporization can be beneficial for fuel–oxidizer mixing and subsequent combustion, but it poses the risk of spray collapse. [see more]
Analysis of Gas-Assisted Pulverized Coal Combustion in Cambridge Coal Burner CCB1 Using FPV-LES
Authors: Y. Chen, O. T. Stein, A. Kronenburg, J. Xing, K. Luo, K.H. Luo and C. Hasse
Gas-assisted pulverized coal combustion in the laboratory-scale Cambridge Coal Burner configuration CCB1 is studied using a large eddy simulation (LES) coupled with a multistream flamelet/progress variable (FPV) model in an Euler−Lagrange framework. The FPV-LES implementation is coupled with an enthalpy correction method for two-phase energy transfer. Both nonreacting and reacting (pure pilot and coal flame) cases are simulated, and the simulation results are compared with the experimental evidence. [see more]
Primary breakup regimes for cryogenic flash atomization
Authors: D. D. Loureiro, J. Reutzsch, A. Kronenburg, B. Weigand and K. Vogiatzaki
Flash boiling atomization can occur in rocket thrusters operating in the vacuum of space when the cryogenic liquid propellants are injected into the reaction chamber just before ignition. The sudden drop in pressure triggers the nucleation of microscopic vapour bubbles that grow in the superheated liquid, leading to extreme jet expansion and atomization. [see more]
