Fluid-kinetic multiscale solver for wall-bounded turbulence
Akshay Chandran, Praveen Kumar Kolluru, Berni J. Alder +2
We present a two-level (fluid-kinetic) coupling procedure for the simulation of wall-bounded flows at Reynolds numbers up to thousands. The method combines a kinetic Direct Simulat…
Lattice Boltzmann Model for Transonic Flows
M. Atif, N. H. Maruthi, P. K. Kolluru +2
The hydrodynamic limit of a discrete kinetic equation is intrinsically connected with the symmetry of the lattices used in construction of a discrete velocity model. On mixed latti…
Essentially entropic lattice Boltzmann model: Theory and simulations
Mohammad Atif, Praveen Kumar Kolluru, Santosh Ansumali
We present a detailed description of the essentially entropic lattice Boltzmann model. The entropic lattice Boltzmann model guarantees unconditional numerical stability by iterativ…
Reduced kinetic model of polyatomic gases
Praveen Kumar Kolluru, Mohammad Atif, Santosh Ansumali
Kinetic models of polyatomic gas typically account for the internal degrees of freedom at the level of the two-particle distribution function. However, close to the hydrodynamic li…
Lattice Boltzmann Method for wave propagation in elastic solids with a regular lattice: Theoretical analysis and validation
Maxime Escande, Praveen Kumar Kolluru, Louis Marie Cléon +1
The von Neumann stability analysis along with a Chapman-Enskog analysis is proposed for a single-relaxation-time lattice Boltzmann Method (LBM) for wave propagation in isotropic li…
Lattice Boltzmann model for weakly compressible flows
Praveen Kumar Kolluru, Mohammad Atif, Manjusha Namburi +1
We present an energy conserving lattice Boltzmann model based on a crystallographic lattice for simulation of weakly compressible flows. The theoretical requirements and the method…
