SIMULATION OF 2D FLOW AROUND OF AIRFOILS AT LOW-SPEED WIND TUNNEL WITH OPEN JET TEST-SECTION
Научный вестник МГТУ ГА, 2019 At present, there is a great interest in the development of new airfoils for wind turbines and high-lift wings of unmanned aerial vehicles (UAV). The requirements for such airfoils differ from conventional aircraft airfoils, because of structural reasons

A new design concept for indraft wind-tunnel inlets with application to the national full-scale aerodynamic complex [PDF]
The present inlet design concept for an indraft wind tunnel, which is especially suited to applications for which a specific test section flow quality is required with minimum inlet size, employs a cascade or vaneset to control flow at the inlet plane ...

Turbulent flow over a house in a simulated hurricane boundary layer [PDF]
arXiv, 2009 Every year hurricanes and other extreme wind storms cause billions of dollars in damage worldwide. For residential construction, such failures are usually associated with roofs, which see the largest aerodynamic loading. However, determining aerodynamic loads on different portions of North American houses is complicated by the lack of clear load paths ...

Conductive Polymer Coatings Control Reaction Selectivity in All‐Iron Redox Flow Batteries
Advanced Materials, EarlyView.Aqueous redox flow batteries are limited by the competing hydrogen evolution reaction (HER) at their negative electrodes. In this work, conductive polymers are conformally coated on porous carbonaceous electrodes to improve the reaction selectivity of hybrid all‐iron redox flow batteries.

Design, construction and characterization of a wind tunnel [PDF]
, 2015 The wind tunnel is the most fundamental test equipment for aircraft testing and studying aerodynamics. Because of the complexity of the test-subject\u27s geometry, it is difficult to study the aerodynamic pattern simply based on theoretical calculations.

Advanced Materials, EarlyView.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Analytical Models for Rotor Test Module, Strut, and Balance Frame Dynamics in the 40 by 80 Ft Wind Tunnel [PDF]
A mathematical model is developed for the dynamics of a wind tunnel support system consisting of a balance frame, struts, and an aircraft or test module. Data are given for several rotor test modules in the Ames 40 by 80 ft wind tunnel.

Transonic wind tunnel test sections
ZAMP Zeitschrift für angewandte Mathematik und Physik, 1956 Um von Windkanalversuchen auf die Verhaltnisse beim freien Flug schliessen zu konnen, mussen die Einflusse der Kanalwande auf die Geschwindigkeitsverteilung am Modell berucksichtigt werden. Bei schallnaher Stromung sind diese Einflusse an Modellen ublicher Grosse so stark, dass sie die Messungen vollstandig verfalschen.
