Numerical simulation of ice destruction by gas dynamic jet

Abstract

When operating gas compressor stations during heavy snowfalls, uncontrolled formation of ice build-up on the filters of air-purifying devices (ACDs) can occur, which leads to accidents and downtime. Previously, it was proposed to use a gas-dynamic system for cleaning gas-permeable deformable surfaces (GPDS) to clean HEU filters. An experimental setup has been created. The paper discusses numerical modeling of ice destruction on the gas turbine engine. To destroy ice, the energy of a gas-dynamic jet is used, modeled as a short-term pulse. The study is carried out in a 3D setting, taking into account the suction flow pressure and the interaction of the deformable substrate with the ice crust. The results obtained were verified. The research is carried out using ANSYS Explicit Dynamics on the high-performance computing complex of PNRPU. The main results on the influence of a gas-dynamic jet on the cleaning ability of a gas turbine engine are presented
