Learn some of the best methods to reduce drag coefficient at low speeds for aircraft design, such as streamlining, wing optimization, boundary layer control, interference drag reduction, and skin ...

1. Distributed roughness elements method (DRE, Saric & al.). A one-time excitation of closely spaced steady CFVs generates a (secondarily) more stable flow scenario and thus delays transition. The ...

Abstract The present work incorporates the effects of boundary-layer suction in designing airfoils for hybrid laminar flow control application. The overall airfoil shape, the suction velocity ...

2. Experiment Technology and Apparatus In this experiment, periodic artificial blow/suction perturbations of different frequencies are introduced into a turbulent boundary layer through a spanwise ...

A region with floor boundary-layer suction upstream of the vehicle to remove the oncoming boundary layer is often used in automotive wind tunnels. These suction systems inevitably change the ...

French ship operator Louis Dreyfus Armateurs (LDA) is to equip one of its vessels with three of the eSAIL suction sail systems developed by Barcelona, Spain, headquartered bound4Blue. The eSAIL ...

‘Boundary Layer Suction’ includes small slots across the surface of a wing, normally utilising an air pump of some kind (In PA474s case, two Budworth turbine engines mounted rear of the bomb bay), to ...

An effort is made to implement the phenomenon called the Aerodynamic Pressure Thrust (APT) for the purpose of effective propulsion of underwater vehicle. The two-dimensional Goldschmied body with ...

There are two types of fuzzy modeling: 1) imitating an expert experiment or fulfilling an engineering knowledge, and 2) modeling a complex or unknown system. In this paper, based on the first type of ...

The Boundary Layer Wind Tunnel in the Hele-Shaw Laboratory within the Faculty of Engineering is a designated National Wind Tunnel Facility, supporting a diverse range of research activities for both ...

Discover the precise measurement of time sequence signals in turbulent boundary layers using IFA300 constant temperature anemometer and double-sensor hot-wire probe. Explore the attenuation ...
