Vortex-Stretching based Large Eddy Simulation Framework for Wind Farms
Jagdeep Singh, Jahrul Alam
In large wind farms, wake distribution behind a wind turbine causes a considerable reduction of wind velocity for downstream wind turbines, resulting in a significant amount of pow…
Dynamic modelling of near-surface turbulence in large eddy simulation of wind farms
Jagdeep Singh, Jahrul Alam
In large eddy simulation of atmospheric boundary layer flows over wind farms, wall-layer models are generally imposed for the surface fluxes without considering the spatial variabi…
Low-dimensional representation of fluid flows using proper orthogonal decomposition
Jahrul Alam, Asokan Variyath
The fluid flow around a bluff body is complex and time dependent, which also contains a wide range of time and length scales. The first few eigenmodes of the proper orthogonal deco…
Subgrid-scale energy transfer and associated coherent structures in turbulent flow over a forest-like canopy
Md. Abdus Samad Bhuiyan, Jahrul M Alam
Large eddy simulation allows to incorporate the important driving physics of turbulent flow through forest- or vegetation-like canopies. In this paper we investigate the effects of…
Large Eddy Simulation of urban boundary layer flows using a canopy stress method
Jahrul M Alam, Luke P. J. Fitzpatrick
Large-eddy simulation (LES) of a turbulent flow through an array of building-like obstacles is an idealized model to study transport of contaminants in the urban atmospheric bounda…
Penetrative turbulence associated with mesoscale surface heat flux variations
Jahrul M. Alam, M. Alamgir Hossain
This article investigates penetrative turbulence in the atmospheric boundary layer. Using a large eddy simulation approach, we study characteristics of the mixed layer with respect…
