The Lattice Boltzmann Method (LBM), e.g. in [1] and [2], can be interpreted as an alternative method for the numerical solution of certain partial differential equations that is not restricted to its origin computational fluid mechanics. interpretation LBM a general tool allows extend solid mechanics well, see [3], which concerned with simulation elastic solids under simplified deformation assu...

The lattice Boltzmann method (LBM) has two key steps: collision and streaming. In a conventional LBM, the streaming is exact, where each distribution function perfectly shifted to neighbor node on uniform mesh arrangement. This advantage may curtail applicability of problems with complex geometries. To overcome this issue, high-order meshless interpolation-based approach proposed handle step. O...

The performance of a single or the collection microswimmers strongly depends on hydrodynamic coupling among their constituents and themselves. We present numerical study for pair based lattice Boltzmann method (LBM) simulations. Our algorithm consists two separable parts. Lagrange polynomials provide discretization captures dynamics surrounding fluid. components couple via an immersed boundary ...

Abstract: As for the measurement of polycyclic aromatic hydrocarbons (PAHs), ultra-performance liquid chromatography (UPLC) is used for PAH identification and densitometry. However, when a solvent containing a substance to be identified passes through a column of UPLC, a dedicated high-pressure-proof device is required. Recently, a liquid chromatography instrument using a monolithic column tech...

This paper studies the three dimensional (3D) simulation of fluid flows through the ball grid array (BGA) to replicate the real underfill encapsulation process. The effect of different solder bump arrangements of BGA on the flow front, pressure and velocity of the fluid is investigated. The flow front, pressure and velocity for different time intervals are determined and analyzed for potential ...

We have adopted a numerical method from computational fluid dynamics, the Lattice Boltzmann Method (LBM), for real-time simulation and visualization of flow and amorphous phenomena, such as clouds, smoke, fire, haze, dust, radioactive plumes, and air-borne biological or chemical agents. Unlike other approaches, LBM discretizes the micro-physics of local interactions and can handle very complex ...

In recent years, Lattice Boltzmann methods (LBMs) have been adapted and developed to simulate the behavior of solids. They already applied fractures as well. However, until now, our previous work has restricted stationary cracks. this work, we regard reduced 2D case anti-plane shear deformation with mode III crack opening. The wave equation is governing for problem, which solved via an LBM. mai...

in this study, we proposed a novel scheme for the implementation of the no-slip boundary condition in thelattice boltzmann method (lbm) . in detail , we have substituted the classical bounce-back idea by the direct immersed boundary specification . in this way we construct the equilibrium density functions in such a way that it feels the no-slip boundaries . therefore , in fact a kind of equili...

Abstract Since the Lattice Boltzmann Method (LBM) showed promising ways in describing fluid flow and convective phenomena, this literature review gives an overview of application LBM to date realm hygrothermal simulations (HAM). Furthermore, apply derive influence convection on moisture transport building components are assessed. This is achieved by a which carried out for specific fields inter...
