This paper presents a consistent LBM formulation for the simulation of a two-phase water–steam system. Results of initial model validation in a range of thermodynamic conditions typical for BoilingWater Reactors (BWRs) are also shown. The interface between the two coexisting phases is captured from the dynamics of the model itself, i.e., no interface tracking is needed. The model is based on th...
Metal foams are interesting as lightweight materials that have an excellent combination of mechanical, thermal, and acoustic properties. However, the production process is currently not fully understood. Therefore, the goal of the FreeWiHR project is the development and high performance implementation of a model for simulating the formation process of metal foams based on the lattice Boltzmann ...
We present a physically-based, yet fast and simple method to simulate gaseous phenomena. In our approach, the incompressible Navier-Stokes (NS) equations governing fluid motion have been modeled in a novel way to achieve a realistic animation. We introduce the Lattice Boltzmann Model (LBM) which simulates the microscopic movement of fluid particles by linear and local rules on a grid of cells, ...
We have examined the responses of energy and protein metabolism to nutrient intake in nine patients with lung carcinoma, of whom none »ere cachexie and only one had distant métastases,compared with nine control patients for elective aneurism surgery, who were comparable in terms of age, body mass index, and smoking habits. Whole-body protein turnover and leucine oxidation were assessed by pri...
Cardiovascular disease (CVD) is the primary cause of death in Korea. Hyperhomocysteinemia confers an independent risk for CVD comparable to the risk of smoking and hyperlipidemia. The purpose of this study was to assess the effect of cardiovascular risk factors and body composition change on homocysteine (Hcy) levels in Korean men and women. The association between body composition and Hcy leve...
Construction and Analysis of Lattice Boltzmann Methods Applied to a 1D Convection-Diffusion Equation
We construct and we analyze two LBM schemes build on the D1Q2 lattice to solve the 1D (linear) convectiondiffusion equation. We obtain these LBM schemes by showing that the 1D convection-diffusion equation is the fluid limit of a discrete velocity kinetic system. Then, we show in the periodic case that these LBM schemes are equivalent to a finite difference type scheme named LFCCDF scheme. This...
BACKGROUND To our knowledge the efficacy of soy-dairy protein blend (PB) supplementation with resistance exercise training (RET) has not been evaluated in a longitudinal study. OBJECTIVE Our aim was to determine the effect of PB supplementation during RET on muscle adaptation. METHODS In this double-blind randomized clinical trial, healthy young men [18-30 y; BMI (in kg/m(2)): 25 ± 0.5] par...
Based on the lattice Boltzmann method (LBM), the lattice Boltzmann flux solver (LBFS), which combines the advantages of conventional Navier–Stokes solvers and lattice Boltzmann solvers, was proposed recently. Specifically, LBFS applies the finite volume method to solve the macroscopic governing equations which provide solutions for macroscopic flow variables at cell centers. In the meantime, nu...
OBJECTIVE Analysis of energy expenditure (EE) in mice is essential to obesity research. Since EE varies with body mass, comparisons between lean and obese mice are confounded unless EE is normalized to account for body mass differences. We 1) assessed the validity of ratio-based EE normalization involving division of EE by either total body mass (TBM) or lean body mass (LBM), 2) compared the in...
abstract: since the field of micro electromechanical systems (mems) continues to grow, the flow in micro devices have become an area that receives a significant attention. the microscopic flows are usually characterized by the knudsen number (kn). when the characteristic size of the particle decreases down to a value comparable to the mean free path of the molecules, the continuum assumption fa...
