Numerical Simulation of Fluid Flow Past a Square Cylinder Using a Lattice Boltzmann Method
The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions. In the presen...
متن کاملA Lattice Boltzmann-Immersed Boundary method to simulate the fluid interaction with moving and slender flexible objects
A numerical approach based on the Lattice Boltzmann and Immersed Boundary methods is proposed to tackle the problem of the interaction of moving and/or deformable slender solids with an incompressible fluid flow. The method makes use of a Cartesian uniform lattice that encompasses both the fluid and the solid domains. The deforming/moving elements are tracked through a series of Lagrangian mark...
متن کاملApplication of lattice Boltzmann method to simulate microchannel flows
Microflow has become a popular field of interest due to the advent of microelectromechanical systems. In this work, the lattice Boltzmann method, a particle-based approach, is applied to simulate the two-dimensional isothermal pressure driven microchannel flow. Two boundary treatment schemes are incorporated to investigate their impacts to the entire flow field. We pay particular attention to t...
متن کاملFluid-Particle Interaction with the Immersed Boundary Lattice Boltzmann Method
The thesis presents an analysis of the continuous forcing approach of the immersed boundary method for the simulation of the interaction between uid and rigid particles in combination with the single relaxation lattice Boltzmann method. The immersed boundary method as a numerical algorithm is implemented in the context of two massively parallel software frameworks (waLBerla and pe) developed at...
متن کاملA Momentum Exchange-based Immersed Boundary-Lattice Boltzmann Method for Fluid Structure Interaction
A new immersed boundary-lattice Boltzmann method (IB-LBM) is proposed and validated in this work by its application to simulate incompressible viscous flows. The conventional IB-LBM based on the lattice Boltzmann equation with external forcing term, which contains a boundary velocity to represent the effect that the moving boundary exerts on the bounce-back distribution functions, whereas the p...
