Papers from conference proceedings generally are not included, though the Proceeding itself may be cited in the introduction. A significant fraction of the papers reviewed herein relates to the science of heat transfer, including experimental, analytical and numerical studies. Other papers cover applications where heat transfer plays a major role, not only in man-made devices but in natural systems as well. The papers are grouped into major subject areas and then into subfields within these areas. In addition to reviewing the literature, we mention major conferences held in 2005, major awards related to heat transfer presented in 2005, and books on heat transfer published during the year.

a b s t r a c t 摘要

Mixed convection heat transfer from longitudinal fins inside a horizontal channel has been investigatedfor a wide range of modified Rayleigh numbers and different fin heights and spacings. An experimentalparametric study was made to investigate effects of fin spacing, fin height and magnitude of heat flux onmixed convection heat transfer from rectangular fin arrays heated from below in a horizontal channel.The optimum fin spacing to obtain maximum heat transfer has also been investigated.

During the experimentsconstant heat flux boundary condition was realized and air was used as the working fluid. Thevelocity of fluid entering channel was kept nearly constant (0.15 6 win 6 0.16 m/s) using a flow rate control valve so that Reynolds number was always about Re = 1500. Experiments were conducted for modified Rayleigh numbers 3 107 < Ra* < 8 108 and Richardson number 0.4 < Ri < 5. Dimensionless fin spacing was varied from S/H = 0.04 to S/H = 0.018 and fin height was varied from Hf/H = 0.25 to Hf/H = 0.80. For mixed convection heat transfer, the results obtained from experimental study show that the optimum fin spacing which yields the maximum heat transfer is S = 8–9 mm and optimum fin spacing depends on the value of Ra*.

从横向通道内的纵向鳍混合对流换热已为修正瑞利数和不同翅片高度和间距的广泛调查。参数的实验研究，探讨混合对流换热鳍片阵列，在水平通道也被调查的最佳翅片间距，以获得最大的传热从下面加热翅片间距，翅片高度和热通量的幅度的影响。在实验中实现了恒热流边界条件和空气作为工作液。流体进入通道保持几乎恒定（0.156胜60.16米/秒），使用流量控制阀，使雷诺数总是约重= 1500。实验进行修正瑞利数3 107

内容：Fins are often used to enhance the rate of heat transfer from heated surfaces to environment. They can be placed on plane surfaces, tubes, or other geometries. These surfaces have been used to augment heat transfer by adding additional surface area and encouraging mixing. When an array of fins is used to enhance heat transfer under mixed convection conditions, the optimum geometry of fins (corresponding to a maximum rate of heat transfer) should be used, provided this is compatible with available space and financial limitations. Advantages in printed circuit boards have yielded increasing power dissipation from surfaces in a channel. Rectangular fins are used extensively to increase the rates of convection heat transfer from systems, because such fins are simple and cheap, to manufacture. Providing adequate cooling of printed circuits boards has recently motivated experiments on the use of longitudinal fins to enhance heat transfer in rectangular channels. The heat transfer, to the fluid flowing through a channel by the heat dissipating surfaces can be obtained mainly by using the mechanisms of heat transfer by forced convection, natural convection and by radiative heat transfer. This paper deals with those issues related to the heat transfer obtained mainly by mixed convection.

a b s t r a c t 摘要

Recent reviews of flow boiling heat transfer in small tubes and channels have highlighted the need for predictive correlations that are applicable over a wide range of parameters and across different studies. A composite correlation is developed in the present work which includes nucleate boiling and convective heat transfer terms while accounting for the effect of bubble confinement in small channels. The correlation is developed from a database of 3899 data points from 14 studies in the literature covering 12 different wetting and non-wetting fluids, hydraulic diameters ranging from 0.16 to 2.92 mm, and confinement numbers from 0.3 to 4.0. The mass fluxes included in the database range from 20 to 3000 kg m 2 s 1, the heat fluxes from 0.4 to 115Wcm 2, the vapor qualities from 0 to 1, and the saturation temperatures from 194 to 97 C. While some of the data sets show opposing trends with respect to some parameters, a mean absolute error of less than 30% is achieved with the proposed correlation Natural convection heat transfer in horizontal and vertical closed narrow enclosures with heated rectangular finned base plate S.A.

attention over the last few years, especially for application to electronics cooling [1–6]. While single-phase flow in small channels can easily be described with equations developed for conventional- sized tubes, microchannel flow boiling is significantly affected by the confinement of bubbles [7–10]. Existing heat transfer correlations are

unable to accurately predict the flow boiling heat transfer coefficient in small channels over a wide range of operating parameters [1,4,11] as the heat transfer mechanisms are not fully understood. A recent review of the literature [1] showed that a pool boiling correlation [12] outperforms dedicated flow boiling correlations when applied to a large database of results from different research groups for channels of hydraulic diameters smaller than 2 mm. However, even the best predictions showed a mean absolute error (MAE) of 40% against the large experimental database, and predicted less than half of the measured data to within a deviation of ±30%. It was also noted in [1] that most of the existing minichannel and microchannel heat transfer correlations were developed based on small data sets [13–20]. As a result, these correlations usually performed well in the parameter range over which they were fit, but did not extrapolate well beyond their often narrow operating range [1].

Abstract摘要

Experiments were conducted to investigate the effect of nanofluid on a boiling heat transfer during a rapid quenching of a thin platinum (Pt) wire. The typical overall boiling curves have been successfully obtained from the cooling curves of the Pt wire for the water, the silicon (Si) and the silicon carbide (SiC) nanofluids. Meaningful differences in the behavior of the boiling curves between the water and the nanofluids cannot be identified during a quenching. However, the Si nanofluids reveal a slightly higher CHF (critical heat flux) than that for the water. On the other hand, a slight

deterioration of CHF is observed in the case of the SiC nanofluids. When the Si and SiC nanoparticle-coated Pt wires are quenched with water, a very high cooling rate is observed and a very different boiling curve from that of the water and the nanofluids appears. Consequently, a considerably large heat transfer coefficient is obtained in a wide range of the wall superheat in the boiling curve.

内容：The na no fluids, which are produced by dispersing na no meter sized particles in traditional base fluids such as water, are expected to have a reasonable potential to enhance a boiling heat transfer [3,8]. Recently, an approach to improve the safety and economics of nuclear power generation systems has been proposed for utilizing the unique heat transfer characteristics of na no fluids [1,4,5]. Several researchers have carried out experiments to confirm the capabilities of na no fluids for a boiling heat transfer [11,14,10,2,7,12]. The general consensus in their researches is that na no fluids enhance critical heat flux (CHF) significantly; however, they have no significant effect on a heat transfer in a nucleate boiling region. Recently, Kim et al.

[7] reported that a CHF enhancement is attributed to a high wettability of a thin layer formed on a heating surface by a deposition of na no particles. Kim et al. [6] concluded that the capillary effect in the microstructures of the na no particle layer

on the heating surface enhances the surface wettability. While most of the studies on a heat transfer of na no fluids have been concentrated on the nucleate boiling region and the CHF phenomenon on a wire heater, some researchers tried to check the effects of na no fluids on the film boiling heat transfer with a sphere or odlet.Park et al. [15] showed that the film boiling heat transfer rate in na no fluids was lower than that in the water for a sphere specimen.
