A numerical model for dilute, three-dimensional, turbulent, incompressible fluid-solid particle flows and its application to a demonstration problem are presented. An Eulerian description is used to model the flow of the fluid (carrier) phase, and th

An experimental apparatus and related procedures for the determination of the effective thermal conductivity of sintered powder-metal plates saturated with distilled water at temperatures in the range 20–150°C are discussed. The apparatus and proc

Numerical methodologies for computer simulations of two-fluid flows are presented. These methodologies fall into the category of volume tracking methods with piecewise-linear interface calculation (PLIC). The scope of this work is limited to laminar

A control-volume finite-element method is used for simulations of flows through coupled fluid-saturated porous and open domains. The Brinkman-Forchheimer equations are used to model the flow in the porous domain. Modeling at the interface is emphasiz

The results of a comparison between traditional one-dimensional (1-D) models and a 1-D/2-D model for closed-loop thermosyphons with vertical heat transfer sections are reported in this paper. Attention is limited to problems in which the flow is lami

The formulation of a control-volume-based finite element method (CVFEM) for axisymmetric, two-dimensional, incompressible fluid flow and heat transfer in irregular-shaped domains is presented. The calculation domain is discretized into torus-shaped e

In this paper, a new 1-D/2-D model is proposed for closed-loop thermosyphons with vertical heat transfer sections. This model improves the results of traditional 1-D models for cases where: (i) mixed-convection effects are important in the heated and

An experimental technique has been developed to visualize water flows in pipes subjected to a uniform wall heat flux (UHF). The technique is based on the use of a thin semitransparent gold-film heater, glued inside a Plexiglas pipe, and dye injection

This paper presents the results of a numerical investigation of conjugate conduction and laminar mixed convection in vertical pipes for upward flow and uniform wall heat flux. The Prandtl number was fixed at 5; the Grashof number, based on heat flux,
