Numerical Uncertainties in Transonic Flow Calculations for Aerofoils With Blunt Trailing Edges

Quantification of Uncertainty in Computational Fluid Dynamics

“…In this case, the error estimate changes and must be less optimistic. A recent application of the GCI to airfoil calculations is given by Lotz et al (1995), which demonstrates the power of the method without the need for integer grid refinement and its application with solution-adaptive grids. Pelletier & Ignat (1995) have shown that the GCI is applicable, at least in a rough sense, to unstructured grid refinement.…”

Pedagogy of an Aircraft Studio

“…Conceptual designs are under ongoing investigation by teams of students in capstone and graduate aircraft design courses at Rensselaer. These teams use a combination of structural analysis codes [14], computational fluid dynamics (CFD) tools [15], and preliminary sizing and stability tools [16,17] to calculate take-off gross weight, performance, loads, basic structure, and stability for a number of different aircraft configurations that address the above goals. Reports are presented to the Advisory Board and include specifications for all major systems, for example, engine, fuel, controls, avionics, structure, cockpit, and payload plus a layout of all major components.…”

“…error have commonly been used interchangeably [21][22][23][24]. It is believed, however, that failure to Validation, on the other hand, provides distinguish between these terms is detrimental to evidence that the right model is solved.…”
