Fluid-thermal-structure Interaction of a Finned Model at Mach 6
Abstract
Cylinder-mounted fins are features common to Naval sea- and air-launched projectiles whose maximum speeds are limited to (approximately) Mach 6 for several reasons, including the fins structural and thermal integrity. The proposed work seeks to study the aerothermodynamic environmentthe fins experience through high-fidelity fluid-thermal-structure interaction (FTSI) simulations, wherein the aerodynamics, fin deformation, and fin conjugate heat transfer are co-dependent and simultaneously simulated. A wall-modeled large-eddy simulation (WMLES) approach is proposed for resolving the near-fin turbulence and will be evaluated against direct numerical simulation(DNS) data at two relevant fin configurations. Subsequent FTSI simulations will explore parameter ranges relevant to cylinder-mounted fins to establish the fundamental features and properties of the unsteady aerodynamic force and thermal loads on the fins, and the concomitant deformationsthat result because of them.
