The lattice Boltzmann method is used to carry out a direct numerical simulation of laminar and turbulent flows in a smooth and rough wall channel or pipe at critical and subcritical Reynolds number. The velocity field is solved using the Lattice Boltzmann Method (LBM) as an alternative numerical approach to computational Fluid dynamics. The method is successfully used to simulate more complex fluid dynamics such as thermal transportation, jet flows, electrokinetic flows and so on. The basic idea of LBM is to construct a simplified kinetic model that incorporates the essential physics of microscopic average properties, which obey the desired Navier-Stokes equations. The computation and visualization will be discussed in this seminar.
About the speaker:
Dr Nisat Nowroz Anika completed her Bachelor and MSc in Applied Mathematics from Khulna University in Bangladesh at the year of 2011 and 2013 respectively. She is currently undertaking a Ph.D. in Mechanical Engineering at the University of Newcastle under the supervision of Professor Lyazid Djenidi. The major focus of her research is mixing at low Reynolds number by generating turbulence.
