A proper orthogonal decomposition (POD) method is used to interpolate the flow around an airfoil for various Mach numbers and angles of attack in the transonic regime. POD uses a few numerical simulations, called snapshots, to create eigenfunctions.

The main objective of this research is to propose a method for decomposing the total drag of a nacelle into external, internal, and wake drag. From a bookkeeping agreement, the internal drag (i.e., the drag generated inside a nacelle) is the engine m

Computation of engine pre-entry thrust is required to evaluate aircraft configuration drag. Numerical computation of this quantity requires knowledge of the captured streamtube, which depends on the stagnation line location. A new method that uses th

A far-field drag prediction and decomposition method has been applied to the results of the AIAA Drag Prediction Workshop 5 held in Louisiana during the summer of 2012. The method has two principal advantages: it allows the removal of spurious drag i

Far-field drag-prediction and decomposition methods are powerful tools that increase the accuracy of the drag coefficient computed from computational fluid dynamics results by removing the spurious drag caused by numerical procedures. Furthermore, th

Current drag prediction and decomposition methods are based on the formulation of the axial velocity defect in the far-field as a function of entropy. However, the formulation of this axial velocit...
