Advanced data transfer strategies for overset computational methods

Abstract

Information on lead redistribution and speciation changes in anthrosphere can help to analyze the whole lead cycle on the earth. Lead life cycle was traced based on the concepts of anthropogenic transfer and transformation. Lead transfer and the distribution of chemical species throughout the anthropogenic flow were identified in 2010 in China. The results show that 1.85 Mt lead ore was consumed (besides 1.287 Mt imported concentrated ore and 1.39 Mt lead scraps. After undergoing transformations, 3.53 Mt lead entered end services in chemical species of Pb, PbO 2 and PbSO 4 , altogether accounting for over 80% of the total lead products. Finally, 2.10 Mt ore was emitted into the environment in such species as PbSO 4 (26%), PbO (19%) and Pb (15%). Lead transfer begins in primary raw material sectors, and then transfers to manufacturing sectors. Lead provides services mainly in such industrial sectors as transportation, electrical power and buildings or construction.

Three-Dimensional Dynamic Overset Method for Stabilized Finite Elements

“…(11), and ] [ is obtained using the following definition [V represents the linearized contributions from the viscous terms that are added to the stabilization matrix to maintain the order of accuracy as the Reynolds number is decreased and viscous terms become dominant, and has been found to be critical for robust and accurate simulations. Note that many alternative stabilization matrices can be derived using flux functions often used in finite-volume schemes can be written as a sum of contributions  F and  F whose eigensystems have positive and negative eigenvalues, respectively.…”

“…For van Leer flux vector splitting, when the Mach number normal to the face is greater than unity (i.e., 1  n M ), the convective fluxes as given in Eq. (11) are utilized based on the appropriate upwind state. For flow where the magnitude of the normal Mach number is less than unity, the three-dimensional van Leer fluxes are given by n…”

“…In terms of mitigating orphan points, subsequent manual intervention is required in the aforementioned software. To this end, a method has been proposed based on scattered data interpolation techniques that eliminates the occurrence of orphan points, 11 and has been used with finite-volume and hybrid approaches that utilize multiple solvers.…”

Numerical method for an assessment of steady and motion-excited flowfields in a transonic cascade wind tunnel

“…The dataset is completed after all orphan cells are eliminated. In the present computation, the receptor cells cannot be donors, and any orphan cells are not allowed since they bring significant numerical error (Quon and Smith, 2015). Figure 3 shows the mesh assembly for the present study.…”

Advanced Data Transfer Strategies for Overset Computational Methods

“…The development of anisotropic basis functions based on local solution gradients is described in Ref. [21]. Rather than developing new basis functions, the present work focuses on applying established RBFs to the problem of overset data transfer.…”
