We analyse the small-scale characteristics, such as enstrophy, total strain and normality/non-normality, in the three-dimensional, separated flow around a NACA 0018 wing using direct numerical simulations. The angle of attack is $10^\circ$ and the Reynolds number (based on the chord length) is $Re_c=5000$. The role of non-normality is investigated by performing Schur decomposition of the velocity gradient tensor. We also apply the Schur decomposition to derive new expressions for the production of enstrophy and total strain arising from the mean flow inhomogeneity. We focus on two sections of the flow, across the recirculating zone and along the transitioning shear layer, and compare our results with homogeneous isotropic turbulence (HIT). Within the recirculating region, the non-normality index is approximately 0 (and close to the HIT value), indicating almost equal normal and non-normal contributions. However, in the separating layer non-normal effects strongly dominate, especially in the region of kinetic energy growth. Only in the decay region do the values of the non-normality index gradually approximate HIT values. The production of enstrophy due to vortex stretching is dominated by the mixed (interaction) term, where normal strain stretches non-normal vorticity. The same component also dominates the strain self-amplification term. The contributions of different QR regions to the production terms are also examined. Production due to mean strain rate is triggered upstream compared with production due to fluctuating strain fields.

In 2008 Bolivia ceased to benefit from US trade preferences, which resulted in thousands of jobs lost thoroughout the country. Without the political will to initiate a trade agreement with the United States, the Morales administration has the opportunity to initiate a trade agreement with the European Union. This study evaluates macro- and microeconomic impacts emerging from a hypothetical trade agreement between Bolivia and the European Union. Our methodology consisted of using a computable general equilibrium model as price generator, and a micro-simulation approach as a bridge to transmit those price changes to the household level under two liberalization scenarios. We conclude that Bolivia could benefit if a trade agreement with the European Union (the second largest importer of goods in the world) is accomplished.
