Methodology for Assessing the Abrasive Particles Separation Effect in Axial Compressors on the Aviation Gas Turbine Engine Characteristics: Simulating Separation and Results

Abstract

The paper presents a methodology for assessing the abrasive particles separation effect in axial compressors on the aviation gas turbine engine characteristics, and considers computational characteristics of the axial compressor experimental setup with an integrated abrasive particle separator. It demonstrates the separator effect on the flow rate, pressure increase ratio, and efficiency. New boundary conditions are obtained for specifying in the separator model. Computational grid of the flow region in the separator is transformed into a high-performance polyhedral grid used in the Fluent package; the grid is converged using the separator cleaning efficiency criterion. The turbulence model from the considered main Reynolds-averaged models is applied in computation. The paper analyzes approaches to simulating the discrete phase motion implemented in the computational fluid dynamics packages. Based on the selected discrete-phase model, it presents the phase mathematical description and numerical simulation of a two-phase flow in the separator. Results of simulating the pressure fields, velocities, and particles tracking are obtained and analyzed, and the separator cleaning efficiency is identified. The paper determines further approaches to studying the abrasive particles separation effect in the axial compressors on characteristics of the gas turbine engines
