Evaluating military training aircrafts through the combination of multi-criteria decision making processes with fuzzy logic. A case study in the Spanish Air Force Academy

TL;DR: A preliminary study of the training aircraft alternatives proposed by the Air Staff and the Logistic Support Command of the Spanish Air Force and the best alternative was shown to be the Pilatus PC-21 aircraft.
Journal ArticleDOI

The final stages of transition and the reattachment region in transitional separation bubbles

TL;DR: In this paper, the evolution of the perturbation velocity spectra found in this zone is first presented, showing the nonlinear growth of instabilities in their path to develop fully turbulent spectra.
Journal ArticleDOI

Heat and mass transfer mechanisms in nanofluids boundary layers

TL;DR: In this paper, the effects of the Schmidt number, the wall temperature, and the particle bulk volumetric fraction on the Nusselt number and the skin-friction coefficient are elucidated and compared to the values obtained for the pure fluid and for uniform mixtures.
Journal ArticleDOI

A predictive model for risk assessment on imminent bird strikes on airport areas

TL;DR: In this paper, the authors proposed a methodology for real-time evaluation of the risk assessment based on avian radar and aircraft data, which can trigger actions or procedures, within enough time, to significantly reduce the risk of a bird strike during critical flight phases.
Journal ArticleDOI

Heat and mass transfer enhancement in a double diffusive mixed convection lid cavity under pulsating flow

TL;DR: Results show that the pulsating regime enhances heat/mass transfer within a square cavity up to a 14%/38% respectively with respect to the non-pulsating case, due to the promotion of additional shear stress fields.
