“…The literature on heat transfer and flow of impinging jets is vast and growing [Martin, 1977;Downs and James, 1987;Hrycak, 1981;Webb and Ma, 1995;Lee and Lee, 2000]. The primary application has been for enhancement of convective heat transfer parameters [Gardon and Akfirat, 1965] so much of the literature concentrated on integral heat transfer quantities, such as local or average heat transfer coefficients (e.g., Goldstein and Behbahani [1982], Hrycak [1983], Baughn and Shimizu [1989], Liu and Lienhard [1993], San, Huang and Shu [1997], , Siba et al [1998], Lee and Lee [2000]) .…”

SummaryWith the University of Idaho, Ohio State University and Clarksean Associates, this research program has the long-term goal to develop reliable predictive techniques for the energy, mass and momentum transfer plus chemical reactions in drying / passivation (surface oxidation) operations in the transfer and storage of spent nuclear fuel (SNF) from wet to dry storage. Such techniques are needed to assist in design of future transfer and storage systems, prediction of the performance of existing and proposed systems and safety (re)evaluation of systems as necessary at later dates.Many fuel element geometries and configurations are accommodated in the storage of spent nuclear fuel. Consequently, there is no one generic fuel element / assembly, storage basket or canister and, therefore, no single generic fuel storage configuration. One can, however, identify generic flow phenomena or processes which may be present during drying or passivation in SNF canisters. The objective of the INEEL tasks was to obtain fundamental measurements of these flow processes in appropriate parameter ranges.With the University of Idaho, an idealization of a combined drying and passivation approach has been defined in order to investigate the generic flow processes. This simulation includes flow phenomena that occur in canisters for high-enrichment and medium-enrichment fuels, where fuel element spacing in the canister is increased as compared with low enrichment fuel. Canister diameter was taken as 46 cm (18 in.) and a single basket of about 1.3 meters (4 ft.) length was considered. A long central tube ("dip tube") served as the inlet as in one earlier concept for a passivation process; while this concept apparently has not yet been selected for application, it provides an excellent example of the coupled, complex phenomena which may be present in canister flows. Suggested design flow rates for this hypothesized application indicate that the Reynolds number in the inlet tube would be expected to be between 2500 and 5000, i.e., relatively low.The local distributions of convective mass transfer characteristics (drying/passivation) are expected to depend on the freestream turbulence in the flow around stored fuel elements. The magnitudes of this turbulence depend on the turbulence distributions on the upstream side of the perforated basket support plate ("inlet plenum") and, in turn, in the impinging jet and in the inlet tube. This information can assist engineers in understanding variations of surface drying and passivation through an array and approaches to modify designs to counter non-uniformities and to improve iii distribution, as well as providing bases for assessment of computational fluid dynamics codes proposed for the purpose.A water-flow experiment with a 3/4-scale model (relative to the idealized canister) has been used for overall flow visualization and velocity measurements, with and without an array of simulated fuel elements. Observations have been made with perforated plates (representing basket support plates) having...

“…There are film, transition and nucleate boiling regimes. The details of the boiling heat transfer and jet impingement can be found in (Bejan [3], Webb and Ma [4]). The most suitable manner of characterizing heat transfer process is to determine the heat transfer coefficient h (HTC), which allows calculating heat flux using a simple Newton's law of cooling.…”

Water spray cooling plays an important role in the steel industry. Continuous casting lines are equipped with the system of water spray nozzles installed in the secondary cooling zones. In the hot rolling mills the spray or laminar cooling systems are employed to reduce the strip temperature before coiling. A suitable rate of cooling must be employed to ensure a proper temperature drop of the worked out material in order to achieve desired properties. Quality of the numerical simulations of the temperature field of the cooled object strongly depends on the thermal boundary conditions. In the literature only average or maximum values of the heat transfer coefficient while spray cooling are available. The experimental stand, numerical models and dedicated software have been developed to study the heat transfer coefficient distribution on the surface of the steel plate cooled by the water sprays. The steel plate is heated in the electric furnace up to the temperature of 907 o C. Next, the hot plate is pushed to the cooling chamber and cooled by the water spray nozzle. The plate temperature has been measured by the 25 thermocouples. The measurements have been employed to determine the distribution of the heat transfer coefficient on the plate surface. The inverse method based on the three dimensional finite element model of the heat conduction in the plate has been employed. The finite element model is based on nonlinear shape function. The heat transfer coefficient varies significantly over the cooled surface of the plate and strongly depends on the plate temperature.
