Transonic aerodynamics of dense gases
Transonic flow of dense gases for two-dimensional, steady state, flow over a NACA 0012 airfoil was predicted analytically. The computer code used to model the dense gas behavior was a modified version of Jameson's FLOS2 airfoil code. The modifications to the code enabled modeling the dense gas …

Surrogate Models for Transonic Aerodynamics for Multidisciplinary Design Optimization
… time. This makes aerodynamic calculations in the transonic regime difficult. Running computational fluid dynamics (CFD) calculations within the MDO code would be too computationally expensive. Instead, CFD is used outside the MDO to find two-dimensional aerodynamic properties of a chosen airfoil …

Data-Driven Multidisciplinary Design and Optimisation of Future Aircraft
… methods proposed accurately model subsonic and transonic aerodynamics, as demonstrated by detailed studies across various operating scenarios. It achieves accuracy comparable to full-order modelling (FOM) while significantly reducing computational cost. Significant improvements are shown in …

Interference Drag Due to Engine Nacelle Location for a Single-Aisle, Transonic Aircraft
… The target aircraft was a single-aisle, transonic aircraft with a freestream Mach number of 0.8 at 35,000 feet and a design lift coefficient of 0.5. Using an MDO framework is necessary for placing the nacelle because of the competing objectives of the disciplines involved in aircraft …

Exploring a Novel Adaptive Mesh Refinement Strategy for High-Speed CFD
… strategy that is developed and evaluated for transonic high-speed flows using Ansys Fluent. The algorithm for marking cells for adaptation is designed to systematically reduce local truncation errors based on the curvature of the primitive vector field. The algorithm for marking cells for …
