The plasma polymerization method and dynamic ion-beam mixed implantation method were employed to coat ultra-thin polymer films on copper plates. Experiments indicated that steady dropwise condensation of steam at atmospheric pressure occurred. The condensation heat transfer coefficients increased by approximately 3 and 5-7 times for the polytrimethylvinylsilane film and polytetrafluoroethylene film respectively, compared with the value for film condensation under the same experimental conditions. The temperatures on the condensing surface and inside the test block were found to be rapidly and randomly fluctuated. The properties of the coated films and advantages of the methods used in this investigation were discussed briefly.

The present paper reports an experimental investigation of film condensation in a vertical, internally finned tube with a wire insert. The finned tube and wire insert were chosen as the best performing from a series of tubes and inserts tested separately in previous investigations. Compared with previous results for the finned tube, it was found that only for ∆T>10K did the addition of the insert somewhat improve the heat transfer performance. However, the pressure drop for the finned tube with insert was increased. Empirical correlations for friction factors for the three tube configurations are proposed based on the present data.

Six surfaces were propared with different surface division patterns for the experimental investigation of steam condensation heat transfer charactc rlstics for dropwise and filmwise coexisting (DFC) condensation surfaces under atmosplmric pressure Dropwise condensation (DWC) was promoted with an uhrathin poly tetrafluorethvene (PiFE) fiim, which was prepared by the dynamic ion-beam mixed implantation (DIMI) method. The results showed that the eondensatiou phenomena at the intersection between the dropwise and filmwise condensation regions wer (quite different ior different relative positions of the dropwise and filmwise condensation regions. The experimental results revealed that the condensation heat transfer characteristics were highly influenced by the surface division number and the relative area ratio of the dropwise and filmwise eondensation regions. The impact of these findings on heat transfer enhancement mechanism for condensation heat transter is discussed in detail.

【期刊论文】Film condensation heat transfer on a vertical porous-layer coated plate *,**

Film condensation on a vertical porous coated plate is investigated numerically for a porous/fluid composite system based on the dispersion effect in the porous coating. The mathematical model improves the conventional matching conditions by considering the stress force at the porous coating interface. The numerical results show the ef-fects of the porous coating thickness, the effective thermal conductivity and the permeability on condensate film thickness and local Nusselt number. The predicted average Nusselt number has similar tendencies to experimental results reported in iterature, such that using a thin porous coating would be a viable alternative for enhancing the condensation heat transfer.

This paper reports the test results of the first industrial-scale absorption heat transformer (AHT) equipment in China, to recover the waste heat released from mixture of steam and organic vapor at 98 C in coacervation section, synthetic rubber plant of Yanshan Petrochemical Corporation, Beijing, China. The recovered heat is used to heat hot water from 95 to 110 C, feeding back to the coagulator as the supplementary heating source. The AHT system is operating with H2O/LiBr solution with heat flow of 5000kW. The coefficient of performance (COP), the thermal efficiency and the temperature lift of the AHT system are presented. The heat transfer characteristics of the AHT components, i.e. absorber, generator, evaporator, condenser and the liquid-liquid solution heat exchanger, are also illustrated by comparison of experimental data and the model calculated results. The results show that the mean COP is 0.47, the gross temperature lift of 25 C can be realized and the payback period is 2 years.

【期刊论文】Analysis on forces and movement of cultivated particles in a rotating wall vessel bioreactor

The forces acting on a microcarrier or a small piece of tissue and its movement in the rotating wall vessel (RWV) bioreactor were analyzed. The tracks of a particle in RWV reactor were calculated under different inner and outer cylinder wall rotating speeds, different particle sizes and different density difference between culture medium and the particle. The results show that cells or particles experience partial microgravity only in the upper area ofRWV, which changes with angle θ, while in the lower part ofRWV, they experience overweight. The trajectory of a moving particle in RWV reactor is an eccentric helix under ground-based condition. And the eccentric degree increases with the decrease of outer wall rotating speed, and with the increase of density difference and particle size. The proper match of rotating speeds of inner and outer cylinder walls is the key to prevent the particle colliding with the walls. For a relatively large piece of cultivated tissue, it can move around the inner wall only when the rotating speed of the outer cylinder is high. And the drag force acting on a particle inside RWV increases with the particle size and the density difference.

Abrief state-of-the-art reviewis presented on research progress on dropwise condensation heat transfer in China. During the past 10 years, Chinese researchers have put forward some new proposals on the mechanism of dropwise condensation, and developed some new surface materials for promoting dropwise condensation. In particular, successful applications of dropwise condensation heat transfer surfaces in industrial condensers have provoked interest around the world and inspired the further investigation on the dropwise condensation. Since much of the work had been published in Chinese, it was considered appropriate to give a review in English. This review includes: (1) micro mechanisms and heat transfer characteristics for dropwise condensation; (2) methods for promoting dropwise condensation and (3) industrial applications of dropwise condensation.

Considering the liquid transverse suction effect at the porous layer interface, a mathematical model was presented to investigate the influence of the porous layer characteristic parameters on condensation heat transfer. The results revealed that the enhancement ratio increased with the increase of the porous layer thickness and permeability. The effective thermal conductivity of the porous layer was, however, of little significance for condensation heat transfer enhancement. Also, the enhancement mechanism was analyzed by comparing the thermal resistances within the external condensate film and the porous layer.

The effect of processing conditions of polymer film on dropwise condensation heat transfer of steam under atmo-spheric pressure is investigated to find an effective technique to prepare a viable polymer film sustaining long-term dropwise condensation pattern state. The polytetrafluoroethylene (PTFE) films were coated on the external surfaces of brass tubes, copper tube, stainless steel tube and carbon steel tube by means of the dynamic ion-beam mixed implantation technique, with a variety of surface processing conditions. The experimental results indicated that heat flux is increased by 0:3-4:6 times and condensation heat transfer coefficient by 1:6-28:6 times of film condensation values for the brass tubes treated with various conditions. The surface processing condition is crucial to the adhesion between polymer film and metal substrate, different substrate material requires different optimal processing condition, and leads to different condensation heat transfer characteristic.

【期刊论文】Lifetime Test of Dropwise Condensation on Polymer-Coated Surfaces

In this paper, a special lifetime testing apparatus is installed for dropwise condensation heat transfer on polymer-coated surfaces. Film and dropwise condensations are simultaneously carried out in the same condensing chamber to get rid of any containments. The discontinuous experimental results demonstrate that one surface has sustained dropwise condensation for about 1000 hours. The condensation heat transfer characteristics tend toward stability. In addition, the experiments prove that a polymer film prepared by the dynamic ion-beam mixed implantation (DIMI) method has good adhesion with the metal substrate.
