1 Mid-Term Review Meeting
ESR Dmytro Iurashev Supervisors: Ing. Federico Daccà, Prof. Alessandro Bottaro Keele

2 M.Sc. in Heat and Power Engineering
Kyiv Polytechnic Institute, Ukraine Keele

3 3.7 Numerical and analytical study of combustion instabilities in industrial gas turbine
In-house code including mean flow and nonlinear effects was developed and implemented in COMSOL environment Limit cycle. Prediction of the amplitude of pressure perturbations Simulations in time domain The main aim: To develop a simplified fast and precise tool able to predict combustion instabilities in industrial gas turbine burners Keele

4 Recent research results
1) Model works like a FILTER Harmonics Noise 2) Changing flow velocity Growth in the amplitude of the pressure fluctuations Decrease in the amplitude of the pressure fluctuations Saturation 3) It is possible to reach Limit Cycle using the proposed model Keele

5 Future investigations
Verification of the model with literature cases 2-D and 3-D models are to be discussed Add motion of the flame Interaction between entropy and acoustic waves Keele 5
