ReviewHeat transfer—A review of 2004 literature
Section snippets
Foreword
The 2004 Heat Transfer Review is considerably different from those of previous years. This year, the key focus is to provide direct access to the heat transfer related articles which have appeared in peer-reviewed journals. This transition is being done to make this Review more helpful to readers. We apologize for the delay in this publication and the inconvenience this might have caused. It required a considerable effort from everybody associated with this review to plan and execute the
1. Introduction
The present review is intended to encompass the heat transfer literature published in 2004. While every attempt has been made to be exhaustive, some selection is inevitable. We restrict ourselves to papers published in English through a peer-review process, with selected translations from journals published in other languages. A significant fraction of the papers reviewed herein relate to the science of heat transfer, comprising experimental, numerical and analytical studies. Others relate to
A. Conduction
In the category of heat conduction in solids structures, and materials, various papers dealing with a wide variety of subcategories appear. In this context, the papers are categorized into: (1) contact conduction/contact resistance, (2) microscale/nanoscale heat transport, and wave propagation, (3) heat transfer in fins, composites, and complex geometries, (4) analytical and numerical methods and analysis, (5) experimental and/or comparative studies, (6) thermal stress and thermomechanical
B. Boundary layers and external flows
Papers on boundary layers and external flows for 2004 have been categorized as follows: flows influenced externally, flows with special geometric effects, compressible and high-speed flows, analysis and modeling techniques, unsteady flow effects, flows with film and interfacial effects, flows with special fluid types or property effects, and flows with combustion and other reactions.
1. External effects
External effects on boundary layers addressed in the 2004 literature include swirl,
C. Channel flows
Heat transfer in channels continues to see considerable attention in the literature both through experimental and computational studies. The largest growth in papers from previous years was in the area of microchannel heat transfer. The review of articles was subcategorized into the following areas: straight-wall channels and ducts; ducts having fins or profiling for heat transfer enhancement; flow and heat transfer in channels in complex geometries; unsteady and transient flow and heat
D. Separated flows
This section deals with papers addressing heat transfer characteristics in flows experiencing separation, either by rapid changes in geometry or strong adverse pressure gradient. This section also includes the thermal behavior of flow past bluff objects, jets, and reattachment.
1. A numerical study examined the flow over staggered oval tubes. Heat transfer control was employed in a backward-facing step flow using miniature electromagnetic actuators. Laminar flow past a cylinder was studied where
DP. Heat transfer in porous media
Fundamental and applied research on heat and mass transfer in porous media span a very wide range of technologies and physical phenomena. This field of research has grown dramatically over the past 25 years, and there appears to be no decrease in the level of interest. Measurement and analysis of single phase free and forced convection for a variety of flows and geometries that mimic systems found in nature and technology are the focus of a large portion of the literature reviewed. Multi-phase
E. Experimental methods
Fundamental and applied experimental heat transfer studies, as well as testing of heat transfer equipment and measurements in a number of natural phenomena, require good experimental methods and equipment including sensors and data acquisition systems. New and improved instrumentation for various parameters of importance to heat transfer studies is continually being developed and modified to provide more accurate, sturdier, more convenient, faster, and more flexible systems. The present section
F. Natural convection—internal flows

The majority of papers in this section consider a vertical flat plate with various fluid and thermal boundary conditions. Wavy vertical plates and plates with ribs are also considered as are heated horizontal plates facing up and down [FF1], [FF2], [FF3], [FF4], [FF5], [FF6], [FF7], [FF8], [FF9], [FF10], [FF11], [FF12], [FF13].

A fundamental study of secondary flows in inclined channels
G. Rotating flows
1. Rotating disks
Temperature distribution is studied for the cases of a rotating disk subjected to an eccentric heat source and surface cooling [G1], wakes behind a disk in a planar stream [G2], sudden subjection to natural convection [G3], in a thin liquid film on a rotating disk [G4], co-rotating disks found in computer disk-drive systems [G5], and in a thermally and mechanically inhomogeneous disk with intermittent heating [G6]. Heat transfer for a disk rotating in a fluid rotating as a
H. Combined heat and mass transfer
Heat transfer and mass transfer are tightly coupled in many scientific and engineering problems. The coupling of the two—often with the fluid dynamics—makes themselves present in a wide variety of physical phenomena. Additionally, isolating the dynamics of heat transfer from mass transfer, or vice versa, is often difficult but considerable attention is given to the area. This subject matter of this section covers the spectrum of combined heat and mass transfer for the current year. The section
I. Bioheat transfer
The present review is only a small portion of the overall literature in this area. This represents work predominantly in engineering journals with occasional basic science and biomedical journals included. This is a very dynamic and cross disciplinary area of research, and thus, this review should be taken as more of an overview, particularly from an engineering point of view, rather than an exhaustive list of all work in this area for this year. Subsections include work in (1) biopreservation,
J. Change of phase—boiling and evaporation
Papers on boiling change of phase for 2004 have been categorized as follows: Those that focus on droplet and film evaporation, bubble characteristics and boiling incipience, pool boiling, film boiling, flow or forced convection boiling, and two-phase thermohydrodynamic effects.

The papers here are divided into these subcategories that focus on the different impacts of radiation. Most of the papers report the results
N. Numerical methods
A relatively new capability available to the researchers and practitioners of heat transfer is the ability to simulate physical phenomena on a computer. The simulation of heat transfer, fluid flow, and related processes is achieved via numerical solution of the governing equations. Such computational simulation is now widely used in fundamental research and in industrial applications. New and improved numerical methods are being developed to improve their accuracy, efficiency, and range of

U. Plasma heat transfer and MHD
This chapter includes the characterization of discharge plasmas through modeling and diagnostics of the fluid flow and heat transfer in a variety of plasma generating devices. These characterizations address the fundamental interactions of plasmas with solids (heat and momentum transfer), as well as the description of specific plasma processes. Because of the multitude of physical effects and the strong non-linearity of any such process, a continuous improvement in the descriptions is seen on
