Several heat transfer correlations have been reported related to single-phase opposing flow; however, these correlations are based on experiments conducted in various channel geometries, working fluids, and thermal flow parameter ranges. Therefore, establishing a guideline for deciding which correlation should be selected based on its range of applicability and extrapolation performance is important. This study reviewed the existing heat transfer correlations for turbulent opposing-flow mixed convection. Furthermore, the authors evaluated the predictive performance of each correlation by comparing them with the experimental data obtained under various experimental conditions. The Jackson and Fewster, Churchill, and Swanson and Catton correlations can accurately predict all the experimental data. The authors confirmed that heat transfer correlations using the hydraulic-equivalent diameter as a characteristic length can be used for predictions regardless of channel-geometry differences. Furthermore, correlations described based on nondimensional dominant parameters can be used for predictions regardless of the differences in working fluids.

Times Cited Count:0 Percentile:0.05(Energy & Fuels)Convection, wherein forced and natural convections are prominent, is known as mixed convection. Specifically, when a forced convection flow is downward, this flow is called opposing flow. Several heat transfer correlations have been reported related to single-phase opposing flow; however, these correlations are based on experiments conducted in various channel geometries, working fluids, and thermal flow parameter ranges. Because the definition of nondimensional parameters and their validated range confirmed by experiments differ for each correlation reported in previous studies, establishing a guideline for deciding which correlation should be selected based on its range of applicability and extrapolation performance is important. This study reviewed the existing heat transfer correlations for turbulent opposing-flow mixed convection and the single-phase heat transfer correlations implemented in the thermal-hydraulic system codes. Furthermore, we evaluated the predictive performance of each correlation by comparing them with the experimental data obtained under various experimental conditions. The Jackson and Fewster, Churchill, and Swanson and Catton correlations (Int. J Heat Mass Transf., 1987) can accurately predict all the experimental data. The effect of the difference in the thermal boundary conditions, i.e., uniform heat flux and uniform wall temperature, on the turbulent mixed-convection heat transfer coefficient is not substantial. We confirmed that heat transfer correlations using the hydraulic-equivalent diameter as a characteristic length can be used for predictions regardless of channel-geometry differences. Furthermore, correlations described based on nondimensional dominant parameters can be used for predictions regardless of the differences in working fluids.

(1) The denitrifying bacteria, the sulfate restoration bacteria, the methanation bacteria and the organic substrate (the cement admixture, the cellulose and the asphalt, TBP) decomposing bacteria were extracted as the important microbes which can be active on the basis of both previous studies on the microbes in deep underground and coexisting substrate. (2) The total amount of calcium hydrate in the repository exceeded the equivalent amount of that for reacting the total Co generated from microbial decomposition of organic substrate and phosphate generated from the microbial decomposition of TBP. Therefore, the impacts of lowering pH by the metabolic products was not considered to be significant. Furthermore, impacts of alteration of both bentonite and cementitious materials and metal corrosion due to the drop of pH are not considered to be significant. (3) The N gas evolution rate due to the denitrifying reaction by microorganisms dominated the total gas evolution rate, if time dependent reduction of corrosion rate was employed. However, the H gas evolution rate in the case is similar to those of N gas due to the denitrifying reaction mentioned above, if time dependent reduction of corrosion rate was neglected. (4) The information of the impacts of the complex formation between nuclides and metabolic products of microbes, colloid formation (including the colloidal behavior of microbes) and CH formation due to microbial activities is limited. The impacts are also considered to depend on the site character. Therefore the limited availability of information and site dependency prevent us from assessing the previous impacts at present. The further accumulation of knowledge is necessary for the assessments.
