The numerical analysis of hydrogen combustion in chamber of aviation turbo engine

100%

Jesionek K. , Błoński D. , Pospolita W.

tom Vol. 37 nr 1

5--14

The article presents the preliminary work on the adaptation of the combustion chamber of aviation turbo-shaft engine to supply it with hydrogen for ground energy generation purposes. Difficulties and problems of both design and operational matters for the use of hydrogen as a basic fuel have been presented. The paper presents mathematical formulation, boundary conditions and assumptions for the concept. With the use of ANSYS CFX commercial code a hydrogen combustion process for pre-optimized design of the burner has been simulated. The results are presented in the form of distributions of temperature, velocity and concentrations of individual components which were used to analyze the changes that have occurred in the combustion kinetics after using gaseous fuel. Results indicated the direction of further work on the optimization of processes occurring in the combustion chamber of the turbo-shaft engine.
