Computational Fluid Dynamics on Hypercubes
نویسنده
چکیده
We discuss some issues that arise in the implementation of numerical algorithms for computational fluid dynamics (CFD) on multiprocessor systems such as hypercubes. We identify several important kernel numerical algorithms from CFD that map well onto the hypercube architecture. We emphasize the importance of considering the optimal mapping for a collection of kernel algorithms used in an application program rather than just on individual optimal mappings. Several examples illustrating the tradeoffs between rearranging data to fit a particular kernel algorithm and using suboptimal mappings will be discussed.

Computational fluid dynamics study and GA modeling approach of the bend angle effect on thermal-hydraulic characteristics in zigzag channels
In the study, the thermal-hydraulic performance of the zigzag channels with circular cross-section was analyzed by Computational Fluid Dynamics (CFD). The standard K-Ꜫ turbulent scalable wall functions were used for modeling. The wall temperature was assumed constant 353 K and water was used as the working fluid. The zigzag serpentine channels with bend angles of 5 - 45° were studied for turbul...
متن کاملInvestigation of stepped planning hull hydrodynamics using computational fluid dynamics and response surface method
The use of step at the bottom of the hull is one of the effective factors in reducing the resistance and increasing the stability of the Planning hull. The presence of step at the bottom of this type of hulls creates a separation in the flow, which reduces the wet surface on the hull, thus reducing the drag on the body, as well as reducing the dynamic trim. In this study, a design space was cre...

It is necessary to obtain a fundamental understanding of the goaf gas flow patterns in longwall mine in order to develop optimum goaf gas drainage and spontaneous combustion (sponcom) management strategies. The best ventilation layout for a longwall underground mine should assist in goaf gas drainage and further reduce the risk of sponcom in the goaf. Further, in the longwall panel, regulators ...
