Effects of the Coriolis force on the coherent structures in conventionally neutral atmospheric boundary layers
Changlong Wang, Luoqin Liu, Xiang I. A. Yang +1
It is well known that the Coriolis force due to Earth's rotation can induce wind veer in the mean flow velocity of an atmospheric boundary layer (ABL), but much less is known about…
The mean wind and potential temperature flux profiles in convective boundary layers
Luoqin Liu, Srinidhi N. Gadde, Richard J. A. M. Stevens
We develop innovative analytical expressions for the mean wind and potential temperature flux profiles in convective boundary layers (CBLs). CBLs are frequently observed during day…
Evaluating the accuracy of the actuator line model against blade element momentum theory in uniform inflow
Luoqin Liu, Lucas Franceschini, Daniel F. Oliveira +3
We evaluate the accuracy of the actuator line model (ALM) approach by performing simulations for the NREL~5~MW wind turbine in uniform inflow using three large eddy simulation code…
Enhanced wind-farm performance using windbreaks
Luoqin Liu, Richard J. A. M. Stevens
The flow speed-up generated by windbreaks can be used to increase the power production of wind turbines. However, due to the increased drag imposed by the windbreaks, their use in…
Universal Wind Profile for Conventionally Neutral Atmospheric Boundary Layers
Luoqin Liu, Srinidhi N. Gadde, Richard J. A. M. Stevens
Conventionally neutral atmospheric boundary layers (CNBLs), which are characterized with zero surface potential temperature flux and capped by an inversion of potential temperature…
A new similarity law for transonic-supersonic flow
Luoqin Liu
How to determine accurately and efficiently the aerodynamic forces of the aircraft in high-speed flow is one of great challenges in modern aerodynamics. In this Letter we propose a…
Numerical validation and physical explanation of the universal force theory of three-dimensional steady viscous and compressible flow
Shufan Zou, Luoqin Liu, Jiezhi Wu
In a recent paper, Liu et al. [``Lift and drag in three-dimensional steady viscous and compressible flow'', Phys. Fluids 29, 116105 (2017)] obtained a universal theory for the aero…
Instabilities driven by diffusio-phoretic flow on catalytic surfaces
Yibo Chen, Kai Leong Chong, Luoqin Liu +2
We theoretically and numerically investigate the instabilities driven by diffusiophoretic flow, caused by a solutal concentration gradient along a reacting surface. The important c…
Wall modeled immersed boundary method for high Reynolds number flow over complex terrain
Luoqin Liu, Richard J. A. M. Stevens
Modeling the effect of complex terrain on high Reynolds number flows is important to improve our understanding of flow dynamics in wind farms and the dispersion of pollen and pollu…
Zonal structure of unbounded external-flow and aerodynamics
Luoqin Liu, Linlin Kang, Jiezhi Wu
This paper starts from the far-field behaviours of velocity field in externally-unbounded flow. We find that the well-known algebraic decay of disturbance velocity as derived kinem…
Lift and drag in three-dimensional steady viscous and compressible flow
Luoqin Liu, Jiezhi Wu, Weidong Su +1
In a recent paper, Liu, Zhu and Wu (2015, {\it J. Fluid Mech.} {\bf 784}: 304) present a force theory for a body in a two-dimensional, viscous, compressible and steady flow. In thi…
