Effects of the intrinsic three-dimensionalization of laminar separation bubbles on the amplification of external disturbances
(2018-01-01)
The size and behavior of laminar separation bubbles is strongly related to the laminar-to-turbulent transition process that takes place downstream of the separation of the laminar boundary layer. Wind-tunnel experiments ...
Enhancement of disturbance wave amplification due to the intrinsic three-dimensionalisation of laminar separation bubbles
(2019-10-01)
Previous studies demonstrated that laminar separation bubbles (LSBs) in the absence of external disturbances or forcing are intrinsically unstable with respect to a three-dimensional instability of centrifugal nature. This ...
Convection in a rectangular channel with a flow of water in laminar-turbulent transition with high heat fluxes
(Planta Piloto de Ingeniería Química, 2010-02)
In this work we examine the phenomenon of laminar-turbulent transition in a heated rectangular channel under high heat fluxes and water as a working fluid. We use an experimental device that allows the electric heating of ...
Análise de estabilidade linear de escoamentos bidimensionais do Fluido Oldroyd-B
(Universidade Estadual Paulista (Unesp), 2016-06-27)
Diversos escoamentos de interesse prático são de fluidos viscoelásticos e muitas vezes é desejável saber se estes escoamentos propagam-se no estado laminar ou no turbulento. Embora a hidrodinâmica de fluidos viscoelásticos ...
Transition to turbulence in the Reynolds' experiment
(Elsevier B.V., 2001-08-01)
In this study we simulate numerically the Reynolds' experiment for the transition from laminar to turbulent flow in a pipe. We present a discussion of the results from a dynamical systems perspective when a control parameter, ...
