Optimization of pipeline reducer using computational fluid dynamics (CFD) modelling

Utilising Computational Fluid Dynamics (CFD) for the Modelling of Granular Material in Large-Scale Engineering Processes

In this paper, the framework is described for the modelling of granular material by employing Computational Fluid Dynamics (CFD). This is achieved through the use and implementation in the continuum theory of constitutive relations, which are derived in a granular dynamics framework and parametrise particle interactions that occur at the micro-scale level. The simulation of a process often met ...

Computational fluid dynamics analysis and geometric optimization of solar chimney power plants by using of genetic algorithm

In this paper, a multi-objective optimization method is implemented by using of genetic algorithm techniques in order to determine optimum configuration of solar chimney power plant. The objective function which is simultaneously considered in the analysis is output power of the plant. Output power of the system is maximized. Design parameters of the considered plant include collector radius (R...

Optimization of cardiovascular stent design using computational fluid dynamics.

Coronary stent design affects the spatial distribution of wall shear stress (WSS), which can influence the progression of endothelialization, neointimal hyperplasia, and restenosis. Previous computational fluid dynamics (CFD) studies have only examined a small number of possible geometries to identify stent designs that reduce alterations in near-wall hemodynamics. Based on a previously describ...

Modelling Sieve Tray Hydraulics Using Computational Fluid Dynamics

The ability of Computational Fluid Dynamics (CFD) to model the complex two-phase hydrodynamics of sieve trays is examined. The key to a proper description of the flow is the estimation of the momentum exchange, or drag, coefficient between the gas and liquid phases. In the absence of sound theoretical models, empirical correlations for the average gas fraction on the tray, such as those of Benn...
