Xanthoria parietina mycobiont was isolated and cultured under axenic conditions. The development of the fungi in aposymbiotic culture depended on the carbon source present in the nutritive medium. The highest development was obtained with 4% glucose in LBM. Nevertheless, the major yield of spore germination was in BBM medium. When the sporulation process was carried out in LBM (without contamin...

We introduce new versions of lattice Boltzmann methods (LBM) for incompressible binary mixtures where fluctuations of total density are inhibited. As a test for the improved algorithms we consider the problem of phase separation of two-dimensional binary mixtures quenched from a disordered state into the coexistence region. We find that the stability properties of LBM are greatly improved. The ...

The present study evaluated growing mink (Neovison vison) as a model for dietary protein quality assessment of protein meals used in extruded dog foods. Three foods with similar CP content but of different protein quality were produced using different protein meals. The protein meals varied with respect to CP digestibility and AA composition and included lamb meal (LBM), poultry meal (PM), and ...

In recent years, the lattice Boltzmann equation has developed into a promising technique for computational fluid dynamics (CFD). The model (LBM) approach is derived from and kinetic theory, as opposed to standard CFD methods that are based on direct discretization of Navier–Stokes equations. this paper, Newtonian flow passing through wavy walled channel been examined laminar turbulent transitio...

Homogeneity is of utmost importance in some applications light-burnt magnesia (LBM), such as shrinkage compensation cement composites, because if it not detected reliably before application, causes unpredicted expansion and cracking. This paper presents an accelerated method for homogeneity thermal history detection LBM. The proposed provides equation computing the weighted mesopore probability...

The performance of many CFD applications, like the lattice Boltzmann method (LBM), on popular cluster computers can fall far short of the impressive peak performance numbers. Using a large scale LBM application, we demonstrate the different performance characteristics of modern supercomputers. Classical vector systems (NEC SX8) still combine excellent performance with a well established optimiz...

We describe a high-performance implementation of the lattice Boltzmann method (LBM) for sparse 3D geometries on graphic processors (GPU). The main contribution of this work is a data layout that allows to minimise the number of redundant memory transactions during the propagation step of LBM. We show that by using a uniform mesh of small three-dimensional tiles and a careful data placement it i...

We propose a numerical approach based on the Lattice-Boltzmann (LBM) and Immersed Boundary (IB) methods to tackle the problem of the interaction of solids with an incompressible fluid flow, and its implementation on heterogeneous platforms based on data-parallel accelerators such as NVIDIA GPUs and the Intel Xeon Phi. We explain in detail the parallelization of these methods and describe a numb...

16 In this paper the Discrete Element Method (DEM) is coupled with the Lattice-Boltzmann 17 Method (LBM) to model the undrained condition of dense granular media that display significant 18 dilation under highly confined loading. DEM-only models are commonly used to simulate the 19 micromechanics of an undrained specimen by applying displacements at the domain boundaries 20 so that the specimen...

Compared to conventional techniques in computational fluid dynamics, the lattice Boltzmann method (LBM) seems to be a completely different approach to solve the incompressible Navier-Stokes equations. The aim of this article is to correct this impression by showing the close relation of LBM to two standard methods: relaxation schemes and explicit finite difference discretizations. As a side eff...
