Study of surface roughness effect on a bluff body — The formation of asymmetric separation bubbles
(2020-11-01)
Turbulent flows around bluff bodies are present in a large number of aeronautical, civil, mechanical, naval and oceanic engineering problems and still need comprehension. This paper provides a detailed investigation of ...
Effects of surface roughness and wall confinement on bluff body aerodynamics at large-gap regime
(2021-08-01)
A purely Lagrangian vortex method is employed to investigate turbulent flows past a rough circular cylinder under moving wall effect at large-gap regime, namely h*/d* = 0.45 and 0.80 (h* establishes the gap height between ...
Development of a new Lagrangian vortex method for evaluating effects of surfaces roughness
(2019-03-01)
The main contribution of this paper is to develop a new methodology to include effects of surface roughness on aerodynamic of bodies. The numerical approach simulates the mechanism of vortex shedding of a rough circular ...
Control and suppression of vortex shedding from a slightly rough circular cylinder by a discrete vortex method
(2020-09-01)
A discrete vortex method is implemented with a hybrid control technique of vortex shedding to solve the problem of the two-dimensional flow past a slightly rough circular cylinder in the vicinity of a moving wall. In the ...
