عنوان انگلیسی Simulation of fouling effects on a two-stage axial turbine performance
چکیده انگلیسی مقاله The axial turbine is one of the most important components of gas turbines in industrial and aerospace applications. As time passing the increasing of the roughness of the axial turbine blades is unavoidable. The aim of this paper is numerical investigation of the blades roughness effects on the flow field and performance of a two-stage axial gas turbine. In this research, the axial turbine is simulated three-dimensionally and the results are validated with experimental data. Then, the effects of blade roughness on flow field and performance of the turbine are investigated in five different pressure ratios. Also, in order to determine the role of stators and rotors roughness in decreasing the turbine efficiency, in a specific roughness, the first and second stators and then the corresponding rotors have been simulated separately. Numerical results show that the efficiency drop in the turbine stage is approximately equal to summation of efficiency drops when the roughness effect on the stator and rotor blades is applied, separately.
