Combustion Models for Industrial Applications (COMBINA)

Combustion processes are an essential component of energy conversion and their accurate modeling is required if the objectives of reduction of fuel consumption and emissions are to be realized. Meeting these requirements will involve a substantial effort, in particular towards the development and availability of accurate and reliable simulation tools for reactive flows and more experimental data. In the COMBINA project, collaboration between a CFD software developing SME, which is coordinating this project, four major research groups on combustion and an SME specialized in experimental analysis of combustors is established. The research partners are originating from Belgium, Netherlands, France, Germany and Turkey. The partners will share and contribute with complementary expertise on the modeling of premixed, partially premixed and spray combustion including RANS and LES modeling and the generation of new experimental results for their validation. An industrial observer group (IOG) of representatives from the gas turbine manufacturing industry will advice the consortium on longer term industrial objectives and provide additional test cases. The current COMBINA project opens new pathways across the different sectors. The coordinating SME-1 is having the most recent numerical combustion models integrated in its software system towards the demands of end users in the manufacturing industry. SME-2 will benefit from intensive exchanges and transfers on experimental and numerical techniques and tools. The university partners will gain access to industrially relevant testcases from SME-2 and the IOG and to an industrial CFD software environment for testing advanced models on real-life applications that so far have only been applied with academic codes on simplified configurations. Actions towards networking and dissemination will involve training activities, as well as two workshops, on combustion modeling and on experimental techniques for combustors.


Investigation of SO2 removal characteristics with limestone under oxycombustion conditions
Avşaroğlu, Sevil; Sanin, F. Dilek.; Department of Environmental Engineering (2019)
One of the technologies to increase combustion efficiency and decrease CO2 and other emissions is Oxy-Fuel Combustion. Combustion efficiency is higher and emissions are lower when the oxygen concentration of air is higher. In this thesis different characteristics of two indigenous Turkish lignites are investigated by Thermal Gravimetric Analysis (TGA). Pyrolysis is carried out under both N2 and CO2 atmospheres and combustion characteristics is also examined. CO2 acts as an inert gas at lower temperatures. T...
Computational fluid dynamics simulation of the combustion process, emission formation and the flow field in an in-direct injection diesel engine
Barzegar, Ramin; Shafee, Sina; Khalilarya, Shahram (National Library of Serbia, 2013)
In the present paper, the combustion process and emission formation in the Lister 8.1 in-direct injection diesel engine have been investigated using a computational fluid dynamics code. The utilized model includes detailed spray atomization, mixture formation and distribution model which enable modeling the combustion process in spray/wall and spray/swirl interactions along with flow configurations. The analysis considers both part load and full load states. The global properties are presented separately re...
Modeling and optimization of hybrid electric vehicles
Özden, Burak Şamil; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2013)
The main goal of this thesis study is the optimization of the basic design parameters of hybrid electric vehicle drivetrain components to minimize fuel consumption and emission objectives, together with constraints derived from performance requirements. In order to generate a user friendly and flexible platform to model, select drivetrain components, simulate performance, and optimize parameters of series and parallel hybrid electric vehicles, a MATLAB based graphical user interface is designed. A basic siz...
Catalytic effects of metallic additives on the combustion properties of crude oils by thermal analysis techniques
Kök, Mustafa Verşan (2001-08-20)
Differential scanning calorimetry (DSC) was applied to crude oil combustion in the presence and absence of metal chlorides. It was observed that in the presence of smaller ratios of metallic additives, the surface reactions were predominant and the catalyst did not affect the reactions much. Three reaction regions were identified as low temperature oxidation (LTO), middle temperature oxidation (MTO) and high temperature oxidation (HTO). Kinetic parameters of the reaction regions were determined with two dif...
Aerothermodynamics of turbine blade trailing edge cooling
Tunçel, Tuğba; Kahveci, Harika Senem; Department of Aerospace Engineering (2018)
It is known that the thermal efficiency of gas turbines strongly depends on the turbine entry temperature of the working fluid. This has resulted in increased turbine working temperatures, and peak temperatures in advanced gas turbines have been well above maximum allowable metal temperatures for quite some time. For turbine blades to survive while operating beyond these material temperature limits, internal and external cooling techniques have been developed. Due to structural and aerodynamic restrictions,...
