##### Form Optimization and Interaction Analysis of Plane Symmetry Prism in Air
19th International Scientific Conference "Engineering for Rural Development": Proceedings. Vol.19 2020

In engineering, for many practical applications fluid-body interactions are commonly encountered and thereby these interactions have to be extensively studied. Though this body-fluid interaction is studied in the past, the concept of interaction analysis, form optimization relating to axis symmetry geometries till date mostly need to be further explored. The present work is devoted to the analysis of fluid (air) to body (prism) interaction, form (or shape) optimization taking into account various criteria and energy extraction from air flow by using an axial symmetric body (circular disc shaped geometry with alternate perforated quadrants) with plane symmetry (cylinders) is considered. A simplified mathematical model for engineering calculations is proposed. The model is based on the concept of pressure (compression) and suction zones, when a body is subjected to fluid (air) flow. Initially, all calculations are performed for the geometry under study in constant dimensions. Further, for better efficiency of the overall system, the system parameters are changed in constant continuous steps by a detailed analysis of the fluid-body interaction response surface. The mathematical model has the following assumptions: the fluid (air) flow is laminar, non-compressible (density constant) and the fluid (air) viscous is ignored. All the results obtained are discussed in graphs and explained. Three-dimensional fluid flow simulations are performed in ANSYS, steady state RANS is solved using Krealizable turbulence model, the interaction force (Drag) is obtained for the geometry under study. Finally, the results relating to form (or shape) optimization and the application of the concept are widely discussed.
