abstract = {A computational fluid dynamics (CFD) model of a sieve tray is developed using the lattice Boltzmann method (LBM), a mesoscale simulation framework where macroscopic properties are determined from moments of particle velocity distributions functions. First a 2D version, and then a 3D, are simulated with commercial software Xflow on an Intel Xeon HPC cluster. To validate the simulation, the clear liquid height calculated is compared with the obtained from the Bennett correlation. The 2D model shows an average error of less than 7 %, similar to the correlation error. In the 3D version, the error is around 30 %, a larger value that is attributed to the short time length of the simulation, not reaching steady state. In both cases, characteristic flow patterns of distillation trays are observed and the visualized results show a realistic appearance of the froth regime.},

abstract = {Present-day control systems in a process plant are composed by a heterogeneous collection of hardware and software entities scattered over a set of heterogeneous platforms. This HW/SW heterogeneity is a source of extreme complexity in the control system regarded as a whole. To implement the new complex control systems Distributed Object Computing (DOC) seems the adequate technology. In the global DOC landscape, CORBA is a well known framework for the construction of modularised, object oriented, distributed applications. The use of CORBA-based control systems (CCS) has been investigated recently with promising results demonstrating the use of CORBA for Process Control Systems.},

abstract = {Control systems for process plants are complex applications running in several interacting computers with varying degrees of integration. The construction, deployment and maintenance of the software system is a difficult problem and distributed object oriented technology offers a good way to deal with it. The open standard CORBA provides flexible middleware capable of integrating complex applications in heterogeneous environments, but was originally designed with large business applications in mind and is not perfectly suited for the construction of control systems. Even with recent advances in the real-time specification for CORBA. it is only suitable for soft real-time applications and do not deal with the tight requirements of closed control loops. In this paper, the building of a process control testbed to identify requirements for CORBA control systems, with both predictable and event-driven transports, is presented. The benefits of such technology are discussed.},
