Control of Reynolds number in a high speed wind tunnel
(Departamento de Ciência e Tecnologia Aeroespacial, 2009)
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel ...
Memory retrieval improvement by Heteropterys aphrodisiaca in aging rats
(Universidade de São Paulo, Faculdade de Ciências Farmacêuticas, 2011-12-01)
Few data exists about the pharmacological properties of Heteropterys aphrodisiaca O. Mach. (Malpighiaceae), which is native to the scrubland regions of Brazil. The present study investigated the effects of oral treatment ...

On the functional form of the universal star-formation law
(The American Astronomical Society, 2015)
We study the functional form of the star-formation law using the Vaschy–Buckingham Pi theorem. We find that it should
have the form Sµ S ˙ G
L gas
3 2, where L is a characteristic length that is related to an integration ...

Three-dimensional analysis of air-admission orifices in pipelines during hydraulic drainage events
(Cartagena de Indias, 2022-11-07)
Air valves operate as protection devices in pipelines during drainage processes in order
to mitigate vacuum pressures and control the transient flows. Currently, different authors have
proposed one-dimensional models to ...
Evaluación de la técnica de control de flujo tipo chorro sintético para la modulación de niveles de ruido en flujos de inyección turbulenta
(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería MecánicaDepartamento de Ingeniería Mecánica y MecatrónicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
En esta tesis se estudia el uso la técnica de control activo tipo chorro sintético en un chorro circular turbulento con Reynolds de 11e10^3 y Mach 0.1 usando simulaciones numéricas. Para determinar el efecto de aplicar la ...
