An Efficient Second-Order-in-Time Penalty-Projection Ensemble Eddy Viscosity Method for Parameterized Navier-Stokes Flows
Md Mahmudul Islam, Muhammad Mohebujjaman, Jahrul Alam
We propose a novel, robust, and second-order-accurate parameterized penalty-projection ensemble algorithm for incompressible Navier--Stokes flow problems. The resulting linearized…
Interaction of vortex stretching with wind power fluctuations
Jahrul Alam
The transfer of turbulence kinetic energy from large to small scales occurs through vortex stretching. Also, statistical properties of the subgrid-scale energy fluxes depend on the…
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…
