Wavepackets in Boundary Layers Close to Transonic Speeds
(2015-01-01)
In practical situations, natural transition determines the transition to turbulence process. Experimental evidence suggest that the wave packet evolution is related closely to natural transition. The major part of numerical ...
The low acoustic noise and turbulence wind tunnel of the University of Sao Paulo
(2021-01-01)
This paper introduces the Low Acoustic Noise and Turbulence (LANT) wind tunnel of the Sao Carlos School of Engineering, University of Sao Paulo (USP-EESC), Brazil. The closed-loop wind tunnel features several devices to ...
Vertical distribution of Skewness and asymmetry in a boundary layer on a mobile bed. Experiment and k-omega model comparison
(2014)
As the waves approach the coast, non-linearities become increasingly stronger. The interactions between the waves and loose bottoms then generate complex features within the turbulent boundary layer, which are difficult ...
Uma solução da equação difusão-advecção com o termo contragradiente
Neste trabalho, apresentase uma solução para equação de difusãoadvecção considerando o
termo contragradiente que é um termo adicional. Esse termo adicional contém informações
sobre a assimetria, escala de tem ...
Sediment entrainment under fully developed waves as a function of water depth, boundary layer thickness, bottom slope and roughness
(ELSEVIER, 2010)
Many sediment entrainment equations for oscillatory waves are based on the linear (Airy) theory for deep
water, but at the depth where such waves begin to transport sediments they commonly have trochoidal or
cnoidal ...
Wind tunnel experiments with neutral and convective boundary layer stabilities
(Scientific & Academic Publishing, 2018)
The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. ...
Streaming patterns in Faraday waves
(Cambridge University, 2017)
Waves patterns in the Faraday instability have been studied for decades. Besides therich dynamics that can be observed on the waves at the interface, Faraday waves hidebeneath them an elusive range of flow patterns —or ...
Initial dynamics of initial solid-liquid interface in presence of a thermal gradient
(2014)
In directional solidification experiments an alloy is placed in the thermal gradient assembly and kept stationary to achieve a steady-state thermal profile. During this time an interface motion occurs that is experimentally ...
