要約

An extended model for predicting thermal-hydraulic characteristics of offset strip fin arrays is developed for fluids with Prandtl number greater than unity. This new model is based on the asymptotic behavior for the laminar and turbulent wake regions with an empirically derived correlation for the effect of Prandtl number suppression on the j factor. The proposed models are compared with existing data for air, water, and polyalphaolefin (PAO), and new data for 5W30 engine oil. Model predictions are within ±20 percent or better for most data sets. The new models for f and j cover a wide range of Reynolds number, 1 < Re < 10,000 and Prandtl number, 0.7 < Pr < 620. A total of 39 unique data sets were used in the present model development.
