A 3D analysis of geometrical factors and their influence on air flow around a satellite dish

Abstract

This paper deals with the geometrical characteristics and their influence on the functionality and safety of satellite dishes. Within the paper, a number of 3D models of satellite dishes were formed. All models were established in the software program SolidWorks, and the same software package was used for the analysis of the air flow over the satellite antenna for the conditions at the territory of Belgrade. The analysis of the model provides an insight into the geometrical characteristics of the satellite dishes which would be the most appropriate to adopt in accordance with the requirements of the final product functionality and security. The analysis is based on laboratory tests, which were conducted on satellite dishes. On that occasion, it was concluded that the geometrical characteristics of the antenna itself greatly affect the functionality and safety. In order to simplify and to make a better financial approach to designing the final product-satellite dish, a basic analysis was carried out on the 3D models whose geometric characteristics can be changed . The models were analyzed to yield an optimal solution, since it is possible to get the final product. The paper justifies forming a 3D model and analysing it, and shows the simplicity of the product geometry changes. The obtained final product is to a very large extent functional since it has been tested in the conditions - +-close to the real system where the product should operate.
