Lateral nozzle forces are known to cause severe structural damage to any new rocket engine in development during test. While three-dimensional, transient, turbulent, chemically reacting computational fluid dynamics methodology has been demonstrated to capture major side load physics with rigid nozzles, hot-fire tests often show nozzle structure deformation during major side load events, leading...

There are procedures and methods for verification of coding algebra and for validations of models and calculations that are in use in the aerospace computational fluid dynamics (CFD) community. These methods would be efficacious if used by the glacier dynamics modeling community. This paper is a presentation of some of those methods, and how they might be applied to uncertainty management suppo...

Modern simulation and measurement methods tend to produce meshfree data sets if modeling of processes or objects with free surfaces or boundaries is desired. In Computational Fluid Dynamics (CFD), such data sets are described by particle-based vector fields. This paper presents a summary of a selection of methods for the extraction of geometric features of such point-based vector fields while p...

The main research approaches in Computational Fluid Dynamics (CFD) are grid-based (Euler) or based on particle motion (Lagrange). For interactive fluid simulation, techniques have been developed to use the Graphics Processing Unit (GPU) to speed up the computation using an Eulerian approach. This paper describes an approach for setting up a Lagrangian particle based fluid simulation on the GPU....

I read this book by Peyret and Taylor with pleasure. At last there is an introductory book on computational fluid dynamics that is intelligent, fairly wellinformed, and reasonably up-to-date. Its perspective is not, however, fully consistent with a mathematician's point of view. Computational fluid dynamics (CFD) is the process of solving problems in fluid dynamics numericallyon a computer. It ...

For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computational fluid dynamics) software and desktop computing power have made it possible for some manufacturers to investigate unique fluid flow fields in routine design applications. In this paper, four case studies of CFD in high performance exp...

The objective of this research is to compare the use of empirical correlation with Computational Fluid Dynamics (CFD) simulation in determining the pressure gradient in two-phase flow pipelines at the same inlet condition. In this work, the empirical model of Beggs and Brill model had been used whereas the turbulent model applied in the CFD simulation was the Renormalization Group (RNG) k-ε mod...

The fluid dynamics of the Thoratec HeartMate III (Thoratec Corp., Pleasanton, CA, U.S.A.) left ventricular assist device are analyzed over a range of physiological operating conditions. The HeartMate III is a centrifugal flow pump with a magnetically suspended rotor. The complete pump was analyzed using computational fluid dynamics (CFD) analysis and experimental particle imaging flow visualiza...

A new cell-trapping method for single cell analysis devices at a very rapid flow rate, is designed, fabricated and characterized by controlling shapes of microstructures and their arrangements in array just simply and effectively within the microfluidic channels. We simulated using a commercialized computational fluidic dynamic simulator (CFD-ACE+) and demonstrated experimentally that the cell-...

Transportation of unrefined crude oil from the production unit to a refinery or large storage area by a pipeline is difficult due to the different properties of crude in various areas. Thus, the design of a crude oil pipeline is a very complex and time consuming process, when considering all the various parameters. There were three very important parameters that play a significant role in the t...
