Abstract:

Abstract A 3D-CFD modeling of a two-stage Gifford-McMahan (GM) cryocooler has been conducted using a commercial software, Ansys-CFX. The model contained a quarter of the cryocooler geometry that was simplified to include major functional components and approximated to be axisymmetric. Advanced Ansys-CFX features, such as dynamic meshing, turbulence options, and porous models were used to set up the model. The solutions to illustrate overall flow and heat transfer mechanisms were obtained and presented in this paper. The numerical results were discussed and compared against available experiment

In nuclear power plant (NPP), particulate matter and gaseous pollutant release into the environment in severe accidents. To prevent from this disaster, filtered vented containment system (FVCS) containing venturi scrubber is being installed. The present work herein is the CFD simulation of throat pressure in venturi scrubber. A commercial software ANSYS CFX tool has been selected for this research. Euler-Euler regime is used to get the picture of behavior of fluid dynamics inside the venturi scrubber. Gas and liquid interact with each other in throat section of venturi scrubber. The pressure a

Abstract:

Tall building is the growing pattern of cities, these buildings are highly vulnerable to wind loads. Wind load effects on the high-rise building can be found using wind tunnel testing and CFD tools. Wind tunnel facilities are limited all around the world, so CFD tools can be incorporated. In this study, ANSYS CFX is used to investigate the effects of wind on different shapes of high-rise buildings. The results of numerical simulation are compared with the international standards of various countries. Streamline patterns and pressure contours on different faces are discussed in this paper. It i

Abstract:

Abstract Drilling mud has various functions, one of which is to carry cuttings to the surface. All other things being equal, the removal of cuttings is characterized by the upward velocity. This paper simulates the rheology of polymer-glycolic non-dispersing mud (in particular viscosity) to achieve the required upward velocity in the «Ansys CFX» software. The viscosity of the mud varies from 6 to 12 mPa·s, on production casing drilling in Arctic conditions. The results of the study showed that for such conditions, the viscosity should be in the range from 6 to 8 mPa·s.

Abstract:

The McMaster nuclear reactor (MNR) is an important research facility that not only provides researchers with neutrons for fundamental science, but also supplies the medical industry with isotopes used for cancer treatment. To ensure the safety and performance of the MNR, modeling of the thermal hydraulics during nominal and accidental conditions is required. For such a task, system codes are customarily used. While system codes can assess the safety aspects of complex thermal–hydraulic systems, the question arises whether such systems can be modeled appropriately in a three-dimensional manner,

Abstract:

A secagem de soluções por atomização, nos diversos setores industriais, é amplamente empregada. Entretanto, a otimização do processo, em sua grande maioria, é realizada de modo empírico e implica em certo custo às empresas, além do tempo despendido com testes experimentais. O objetivo do estudo foi observar a variação da temperatura do gás e da fração de massa do vapor de água, e de valores médios do diâmetro das gotas e sua temperatura no secador de pulverização, bem como à medida que a temperatura e o tamanho da água individual diminuem à medida que viajam através do secador de spray dryer.
