  Fluid Structure Interaction Based Investigation on Convergent-Divergent Nozzle and Study of Coating Material
  Author(s): Shridevi S Keralamatti* and Nagappa Pradhani
  
  The aim of this paper is to analyze flow in a rocket nozzle and perform FSI simulation for the thermo-mechanical interaction between fluid and solid structure. The nozzle is most important part of the rocket. The proper design plays a major role in the performance of the nozzle, which is designed aerodynamically while considering NPR values. Nozzle is made with Rhenium and coated with Iridium. High speed flow through Convergent-Divergent nozzle leads to complex loading on surrounding structures. The two different cases are carried out and assist the thermal loading on surrounding structures. Structure Interaction analysis is carried in Star CCM+ by creating three different regions i.e., Fluid, Iridium coating (Solid region of 50 μm) and Rhenium structure (Solid region of 1mm) and this analysis gives a better understanding of the behavior of the thermo-mechanical i..
