(2016-10-26)
Article
Open AccessA lattice Boltzmann method (LBM) 9-bit model is presented to solve mathematical-physical equations, such as, Laplace equation, Poisson equation, Wave equation and Burgers equation. The 9-bit model has been verified by ... -
A modified lattice Boltzmann approach based on radial basis function approximation for the non-uniform rectangular mesh
(2024-11)
Article
Restricted access - publisher's policyWe have presented a novel lattice Boltzmann approach for the non-uniform rectangular mesh based on the radial basis function approximation (RBF-LBM). The non-uniform rectangular mesh is a good option for local grid refinement, ... -

Numerical investigation on the flow around a square cylinder with an upstream splitter plate at low Reynolds numbers
(2020-03-13)
Article
Open AccessThe present study focuses on the flow over a 2D square cylinder with a plate placed in front of it. An in-house code using the lattice Boltzmann method was employed for all the simulations presented. Few cases were simulated ... -
Square cavity flow driven by two mutually facing sliding walls
(2023-07)
Article
Open AccessWe investigate the flow inside a 2D square cavity driven by the motion of two mutually facing walls independently sliding at different speeds. The exploration, which employs the lattice Boltzmann method (LBM), extends on ... -
Square cylinder with passive flow control
(2017)
Conference report
Restricted access - publisher's policyIn the present paper it is presented the flow around a 2D square cylinder which is located downstream of a splitter plate and at a certain distance of it. The fluid velocity below and above the splitter plate is different, ... -
The lid-driven right-angled isosceles triangular cavity flow
(2019-09-25)
Article
Restricted access - publisher's policyWe employ lattice Boltzmann simulation to numerically investigate the two-dimensional incompressible flow inside a right-angled isosceles triangular enclosure driven by the tangential motion of its hypotenuse. While the ... -
Towards a better understanding of wall-driven square cavity flows using the Lattice Boltzmann method
(2020-06-01)
Article
Open AccessWall-driven flow in square cavities has been studied extensively, yet it appears some main flow characteristics have not been fully investigated. Previous research on the classic lid-driven cavity (S1) flow has produced ...
