Sinate-phase heat transfer and pressure drop char96105377 acteristics of an-int’egral-spine fin within ari annulus Kedzierski, M. A. and Kim, M. S. J. of Enhanced Heat Transfer, 1996, 3, (3), 201-210. The laminar, single-phase heat transfer and friction characteristics of a porcupine-like surface (integral-spine fins) within an annulus are presented. The heat-transfer coefficient was determined using a modified version of the Wilson Plot method on a 3 m test section. Three fluids were investigated: (1) water, (2) 35% ethylene glycol/water mixture, and (3) 40% ethylene glycol/water mixture.

A. and Bono, A. Chemical Engineering & Processing, Mar. 1996, 35, (2), 141-155. Sorption of ethanol and water in bi-dispersed pellets formed by compaction of a hydrophobic crystalline molecular sieve,, silicalite,, is examined. The difficulties inherent m the measurement and mterpretallon of mixed liquid adsorption equilibria are discussed and the individual adsorption isotherms for (ethanol-water)/silicalite crystals presented.

A. and Bono, A. Mar. 1996, 35, (2), 157-168. Separation of dilute ethanol-water mixtures in a fixed bed of bi-dispersed hydrophobic adsorbent, silicalite, is considered. The column dynamics are well described with a differential model accounting for axial dispersion, external film mass transfer and intraparticle diffusion. Diffusion within the solid is firmly controlled by transport through the liquid filled non-selective macropores giving access to the selective micropores of the embedded hydrophobic crystals. A sensitivity analysis indicates that, given the adsorption isotherm, all the mass transfer parameters can be estimated or predicted a priori.

A thermodynamic analysisxased on the first andsecond laws iiconducted to evaluate the performance of a thermal vapor compression (TVC) desalination system. The performance of the analytical model is compared with operational data obtained from tests performed on a four-effect, low temperature TVC desalination system with performance ratios of 6.5-6.8, located in the U.A.E. The effect of the process variables on the plant’s performance ratios is investigated. The exergy losses due to irreversibilities in different subsystems of the TVC system are evaluated and compared with those of the conventional multi-effect boiling and mechanical vapour compression desalination systems.

A residential desuperheateriwater heater system was tested in a laboratory under controlled environmental conditions. The desuoerheater, inteerated to a thermal storage system, was installed in the Dual-‘Air Loop’Test Facility at The Center for Energy Studies, The University of Texas at Austin. The major components of &e system consisted of the refrigerant compressor, domestic hot water (DHW) desuperheater, thermal storage tank with evaporator/condenser coil, outdoor air coil, DHW storage tank, DHW circulating pump, space conditioning water circulation pump, and indoor heat exchanger. Although measurements were made to quantify space heating, space cooling, and domestic water heating, the paper only emphasizes the desuperheater/water heater performance of the unit.

Coating of carbon fibers with amor hous SIC films 96105365 as diffusion barriers. by chemical vapor 8 eposltlon with trlisopropylsllane Kusakabe, K. ef al., Carbon, 1996, 34, (2), 179-185. Carbon fibres 6.5 urn in diameter were coated with amorphous Sic films by chemical vapour deposition at temperatures as low as 800-9OO”C, using triisopropylsilane in hydrogen. The morphology of the films was strongly affected by the reaction conditions. The tensile strength of the coated fibres was decreased by the coating, but was little affected by the coating method if smooth and tight films were formed. Sic films formed under optimized conditions effectively protected the fibres from oxidation. When the fibres were enclosed with aluminum at lOOO”C, SIC films effectively retarded the diffusion of aluminum.

The operation method is carried out by adding refractory materials of charlike carbon, inactive carbonaceous materials from dust collecting into the coke-oven chamber via pipe and feeder in a coal-charging chute to relax the raise of swelling pressure during carbonization. Refractories for high-alkali environments 96105387 Rau, A. W. and Cloer, F. Am. Ceram. Sot. Bull., 1996, 75, (l), 71-74. Alkali cup and physical property tests can be used to determine the stability of refractories under alkali attack typical of environments in coal-fired applications. The alkali cup test rates products using a relative numerical scale based on visual appearance. This test indicates the presence and relative degree of chemical attack to the refractoty. The physical properties test determines the specific properties affected by the given contaminant. Thermal treatment of binary carbonaceoushlrconia 96105368 gels and formation of Zr(C,O,N) solid solutions Preiss, H. ef al., Carbon, 1996, 34, (I), 109-119. Binary organic-inorganic gels, in which a carbonaceous gel obtained from a coal tar pitch and a zirconia gel are combined, were prepared as precursors for carbothermal reduction with and without simultaneous nitridation to form Zr(C,O,N) solid solutions.
