Achieving High Convective Volumes in On-Line Hemodiafiltration

Blood Purification, 2013
On-line hemodiafiltration (OL-HDF) has established itself as a highly efficient and safe form of renal replacement therapy, providing clinical benefits for several conditions that afflict end-stage chronic kidney disease patients. Additionally, evidence now ascribes a survival benefit to OL-HDF.

Finite Volume Methods for Convection-Diffusion Problems

SIAM Journal on Numerical Analysis, 1996
Cell-centered finite difference approximations for second-order convection-diffusion equations of divergence type are considered. Approximation of the convection term in such problems by central finite differences leads to schemes of second order, which are stable only for sufficiently small mesh size \(h\). Therefore a number of modified upwind finite

Diffusion-convective extraction into an enclosed volume

Theoretical Foundations of Chemical Engineering, 2008
Four model problems describing the extraction from different systems of capillaries into an enclosed volume are studied. Asymptotic relations for the relative extraction yield at the final stage of the process are found for all studied cases. Comparison with experimental data is made.

A nonoscillatory, characteristically convected, finite volume schemefor multidimensional convection problems

28th Aerospace Sciences Meeting, 1990
A new, nonoscillatory upwind scheme is developed for the multidimensional convection equation. The scheme consists of an upwind, nonoscillatory interpolation of data to the surfaces of an intermediate finite volume; a characteristic convection of surface data to a midpoint time level; and a conservative time integration based on the midpoint rule. This

A new finite‐volume approach with adaptive upwind convection

International Journal for Numerical Methods in Engineering, 1988
AbstractA new finite‐volume approach is developed and applied to the two‐dimensional continuity and convective‐diffusive energy equations. The variation of the field variables is approximated by bi‐quadratic interpolation formulae over the space occupied by the finite volume and the region surrounding it.

Simulation of Turbulent Thermal Convection Using Finite Volumes

2007
To simulate turbulent Rayleigh-Benard convection in cylindrical domains an explicit/semi-implicit finite volume method with fourth order approximations in space was developed. Using this method and cylindrical staggered grids of about 11 million nodes clustered in vicinity of the boundary we performed simulations of turbulent Rayleigh-Benard convection

Effect of Volume Fraction of Nanoparticles to the Convective Heat Transfer of Nanofluids

open access: yesKey Engineering Materials, 2011
A numerical study on the convective heat transfer characteristics of Cu-water nanofluid under the laminar flow condition was performed. The results show that the convective heat transfer coefficient increases with the increase of the volume fraction of ...
