With Computational Fluid Dynamics, Data Center's Cooling Is Optimized
- Theory of radiative shocks in optically thick media. Drake, R. P. // Physics of Plasmas;Apr2007, Vol. 14 Issue 4, p043301
The theory of radiative shocks in optically thick media is discussed, using exact relations for the fluid dynamics quantities. A quantitative, semianalytic approach to the radiation transport is presented here, based on the observation that the mean intensity is essentially constant through the...
- Predicting boiling heat transfer using computational fluid dynamics. Hawley, J G; Wilson, M; Campbell, N A F; Hammond, G P; Leathard, M J // Proceedings of the Institution of Mechanical Engineers -- Part D;May2004, Vol. 218 Issue 5, p509
A study has been undertaken to assess the capability of incorporating different empirical approaches in a computational fluid dynamics (CFD) environment for predicting boiling heat transfer. The application is for internal combustion (IC) engine cooling galleries and experimental validation work...
- Prediction of Distributed Air Leakage in Raised-Floor Data Centers. Karki, Kailash C.; Radmehr, Amir; Patankar, Suhas V. // ASHRAE Transactions;2007, Vol. 113 Issue 1, p219
In raised-floor data centers, the distributed air leakage, which refers to airflow through the gaps between the floor panels, reduces the amount of cooling air available for direct cooling of computer equipment. In this paper, we discuss a methodology for predicting this air leakage, using an...
- Instability and Gradual Loss of Smoothness Inherent in Flows of Perfect Fluid. Yudovich, V. I. // Doklady Physics;Feb2000, Vol. 45 Issue 2, p88
Investigates a specific instability inherent in flows of perfect incompressible fluid and appearing as an unlimited growth of strains in liquid particles. Basic equations and definitions; Loss of smoothness at the boundary and the instability of steady flows; Incompressible motions of a dust...
- Experimental study of controlled tip disturbance effect on flow asymmetry. Degani, David; Tobak, Murray // Physics of Fluids A;Dec92, Vol. 4 Issue 12, p2825
The effect on the asymmetric mean flow observed on pointed bodies of revolution at incidence of changing the size and location of a controlled disturbance as well as changes in angle of attack and flow conditions are evaluated experimentally. Flow visualization and side-force measurements are...
- Cavity flow induced by a fluctuating acceleration field. Thomson, J. Ross; Casademunt, Jaume; Vinals, Jorge // Physics of Fluids;Feb95, Vol. 7 Issue 2, p292
Studies the buoyancy driven convection induced by a fluctuating acceleration field in a two dimensional square cavity. Effect of both deterministic and stochastic acceleration modulations normal to the initial density gradient; Modeling of the acceleration field by narrow band noise.
- Flute vortices in nonuniform magnetic fields. Yu, M. Y.; Shukla, P. K.; Varma, R. K. // Physics of Fluids (00319171);Sep85, Vol. 28 Issue 9, p2925
Localized double vortices associated with the flute modes are shown to exist. Special emphasis is given to the effect of the convective variation of the fluid magnetic moment. It is shown that the latter effect considerably modifies the existence regions of the vortices.
- Concurrent CFD Analysis Methods Boost Automotive Design Productivity. // Motion System Design Exclusive Insight;10/25/2012, p1
The article places emphasis on Concurrent Computational Fluid Dynamics (CFD) analysis methods that are said to increase automotive design productivity.
