Abstract

In multistage axial-flow compressors, the droplet size distribution of the injected fluid depends upon the entry conditions. This paper presents the numerical approach used in the development of a preliminary analytical tool to investigate droplet flow pattern during fluid injection into an axial compressor. An investigation was carried out using the commercial CFD code CFX-TASCflow on the aerodynamics of an axial-flow compressor designed for operation with air while operating with an air-fluid droplet mixture during online washing. A test matrix involving different initial droplet diameters was investigated with the machine rotating at constant shaft speed. The range of droplet sizes used in these simulations is representative of the droplet dimensions used during online washing. The liquid employed in this study was water. The main objective of the investigation is to gain added physical insight into the washing process, through the assembly of a realistic model, describing the movement of liquid phase in an industrial axial compressor. The results are presented to show how varying droplet sizes affect the flow pattern of a representative 260MW Gas Turbines axial compressor during online washing. Furthermore, results are presented for the amount of water collected by the blades due to these tests as well as the quantity of water evaporated. This study shows that the droplet dispersion and flow pattern inside the compressor is strongly influenced by the initial conditions of the droplets during online compressor washing.
