AIRFLOW SIMULATION AT THE UKRAINIAN ANTARCTIC STATION

Abstract

The location of the Ukrainian Antarctic Akademik Vernadsky station leads to several problems related to the need to ensure the livelihood and safety of people. The infrastructure of Vernadsky station is affected by significant climatic loads during the year, such as wind, rain, snow and low temperatures. The destruction or even significant damage to the infrastructure of the Antarctic station can endanger the lives of people who are on it due to the inability to evacuate. The purpose of the study is to determine the fields of wind load distribution within the Antarctic Vernadsky station. This is necessary in order to identify the infrastructure objects that are most affected by wind loads. SolidWorks computer-aided design software environment allows you to build geometric models of objects of varying complexity. That is why this system was chosen to model the infrastructure of the Ukrainian Antarctic Vernadsky station. Simulation modeling of wind load was performed in the computer-aided engineering software of finite element analysis ANSYS. Geometric models of the infrastructure objects of the Ukrainian Antarctic Vernadsky station were created. Simulation modeling of the station under wind load conditions was performed. It is shown that in the case of wind from the mainland, the elements of the station's infrastructure that receive the main wind load are the main building and the VST-200. It is determined that the presence of a pile foundation affects the velocity vector fields, so this element should not be neglected when performing further research. It is shown that practically all objects of the station's infrastructure lead to significant turbulent vortices. Geometric models of the infrastructure objects of the Ukrainian Antarctic station Academician Vernadsky were created. Simulation modeling of the station under wind load conditions was performed. It is shown that in the case of wind from the mainland, the elements of the station's infrastructure that receive the main wind load are the main building and the RVS-200. It is determined that the presence of a pile foundation affects the velocity vector fields, so this element should not be neglected when performing further research. It is shown that almost all infrastructure objects of the station lead to significant turbulent tails when they flow around.
