Propagation of sound waves in air can be considered as a special case of fluid dynamics. Consequently, the lattice Boltzmann method (LBM) for fluid flow can be used for simulating sound propagation. In this article application of the LBM to sound propagation is illustrated for various cases: free-field propagation, propagation over porous and non-porous ground, propagation over a noise barrier,...

The use of lattice Boltzmann methods (LBM) for fluid flow and its coupling with finite element method (FEM) structural models for fluid-structure interaction (FSI) is investigated. A body of high performance LBM software that exploits graphic processing unit (GPU) and multiprocessor programming models is developed and validated against a set of twoand three-dimensional benchmark problems. Compu...

in according to the simplicity of the lattice boltzmann method’s(lbm) algorithm and its benefits, it has been used as a successful method in computational fluid dynamics in the last decades. in this paper, lbm was used to simulate the flow over a cylinder. to analyze the application of lbm in simulation curved surface, different methods to compute drag coefficient were used. these methods are: ...

BACKGROUND Symmetric dimethylarginine (SDMA) is an accurate and precise biomarker for estimating glomerular filtration rate (GFR) in humans and cats. Serum creatinine (sCr) also correlates with GFR, but has limitations as a biomarker of renal function because nonrenal factors can influence its concentration. HYPOTHESIS Differences in lean body mass (LBM) influence sCr, but not serum SDMA conc...

The link-wise artificial compressibility method (LW-ACM) is a recent formulation of the artificial compressibility method for solving the incompressible Navier– Stokes equations. Two implementations of the LW-ACM in three dimensions on CUDA enabled GPUs are described. The first one is a modified version of a stateof-the-art CUDA implementation of the lattice Boltzmann method (LBM), showing that...

The paper presents a synthetic turbulence generator (STG) for the lattice Boltzmann method (LBM) at interface of Reynolds averaged Navier–Stokes (RANS) equations and LBM large eddy simulation (LES). We first obtain RANS velocity field from finite volume solver interface. Then, we apply numerical interpolation to due different grid types LBM. STG generates fluctuations, regularized reconstructs ...

Because primary hypertension (PH) is associated with calcium metabolism, it is hypothesized that PH may be related to osteoporosis risk. The study aimed to evaluate the relationship between body composition and bone strength in hypertensive adolescents. Total body scans using x-ray absorptiometry (DPX-L, GE Healthcare) were performed in 94 PH children aged 6 to 18 years (21 girls and 73 boys). ...

This paper presents a stencil adaptive phase-field lattice Boltzmann method (LBM) for the simulation of two-dimensional multiphase flows. In the phase-field model, the interface is viewed as a layer with finite thickness where physical parameters vary steeply and continuously. In the present study, a phasefield LBM is used. In this model, the Cahn–Hilliard equation can be correctly recovered by...

[1] The lattice Boltzmann method (LBM) has emerged as a powerful tool for simulating the behavior of multiphase fluid systems in complex pore networks. Specifically, the single component multiphase LBM can simulate the interfacial phenomena of surface tension and adsorption and thus be used for modeling fluids such as water and its vapor in porous media. This paper provides an introduction to L...

This study characterized properties of Ti-6Al-4V ELI (extra low interstitial, ASTM grade 23) specimens fabricated by a laser beam melting (LBM) and an electron beam melting (EBM) system for dental applications. Titanium alloy specimens were made into required size and shape for each standard test using fabrication methods. The LBM specimens were made by an LBM machine utilizing 20 µm of Ti-6Al-...
