To investigate the hydrodynamic behaviour of industrial scale bubbling fluidised bed reactors, a 3D Discrete Bubble Model (DBM) has been developed. In the DBM, an Euler-Lagrange model, the bubbles are treated as discrete elements and the bubble trajectories are tracked individually, while the emulsion phase is considered as a continuum and is described with the continuity and Navier-Stokes equa...

We consider Waveform Relaxation (WR) methods for parallel and partitioned time-integration of surface-coupled multiphysics problems. WR allows independent time-discretizations on adaptive time-grids, while maintaining high orders. Classical such as Jacobi or Gauss-Seidel are typically either converge quickly. present a novel method utilizing asynchronous communication techniques to get both pro...

With the rapid development of integrated circuit technology, heat flux electronic chips has been sharply improved. Therefore, dissipation becomes key technology for safety and reliability equipment. In addition, are distributed discretely used periodically in most applications. Based these problems, characteristics transfer performance flow boiling parallel channels with discrete source distrib...

The aim of the performed work is to establish the 2D and 3D model of direct unsteady task of sample heat treatment by moving source employing computer model on the basis of finite element method. Complex boundary condition on heat loaded sample surface is the essential feature of the task. Computer model describes heat treatment of the sample during heat source movement over the sample surface....

Temperature monitoring over heat source components in engineering systems, such as the energy system, electronic equipments, becomes essential to guarantee working performance of these components. However, prior methods, which mainly use interpolate estimation reconstruct overall temperature field from limited points, require large amounts tensors for an accurate estimation. This may affect ava...
