CFD-Simulation von Schwergasausbreitungen
2019Um die Ausbreitung von Schwergaswolken infolge störfallbedingter Freisetzungen in bebautem Gelände besser vorhersagen zu können, soll eine praxisorientierte Methode zur numerischen Simulation von Schwergasausbreitungen entwickelt werden. Dafür muss zunächst die atmosphärische Strömung möglichst realitätsnah abgebildet werden.

CFD Simulations of Sieve Tray Hydrodynamics
Chemical Engineering Research and Design, 1999A Computational Fluid Dynamics (CFD) model is developed for describing the hydrodynamics of sieve trays. The gas and liquid phases are modelled in the Eulerian framework as two interpenetrating phases. The interphase momentum exchange (drag) coefficient is estimated using the Bennett et al. correlation as a basis.

2019
In this chapter, based on the rigorous theory of fluid flow through porous media and the computational fluid dynamic technique, different numerical approaches for description of air and resin flow in fibrous media will be presented. In the analyses, both fibrous media and fluids (resin and air) are considered to be incompressible.

One-Dimensional Simulation (1D-CFD-Simulation)
2011The 1D-CFD-simulation can be seen as an extension of the cylinder real working-process analysis. The latter provides mainly the calculation of the working period of each cylinder (i.e. when the valves are closed) while the 1D-CFD-simulation analyzes the flow field in the whole intake and exhaust track, respectively. This approach can ensure an accurate

CFD/CAA Simulations on HPC Systems
2016In this paper, a highly scalable numerical method is presented that allows to compute the aerodynamic sound from a turbulent flow field on HPC systems. A hybrid CFD-CAA method is used to compute the flow and the acoustic field, in which the two solvers are running in parallel to avoid expensive I/O operations for the acoustic source terms.

Three-Dimensional Simulation (3D-CFD Simulation)
2011The three-dimensional simulation (3D-Computational-Fluid-Dynamics simulation) represents the most sophisticated approach for detailed numerical investigations on any thermo-fluiddynamical problem. This approach is based on the numerical solution of partial differential equations for conservation of mass, species concentration, momentum and energy over ...

CFD simulation of pressure piling
Journal of Loss Prevention in the Process Industries, 2010The explosion of flammable mixtures in interconnected compartments is commonly defined as "pressure piling" Peak pressures much higher than the predictable thermodynamic values are likely to be generated in this geometry, yielding the phenomenon of major interest in industrial safety.

Examples of Contemporary CFD Simulations
2002This chapter is intended to convince the reader, through a number of relevant and diverse examples, that modern CFD with turbulence modelling is a practical tool for fast and accurate prediction of flow problems of engineering interest. A general introduction to modern CFD and a preface to the general-purpose CFD solver, CFD++, are followed by a ...
