Abstract
An experimental research on air side heat transfer and pressure drop performance of twisted oval tube bundle with staggered layout in cross flow is conducted. The comprehensive performance of present twisted oval tube bundle is larger than that of round tube bundle with the same layout by 25.5-33.3% during the experimental range of Remax (7500-18,000). The economic operation Remax among the experimental range is from 7500 to 13,000 for present twist oval tube bundle in cross flow. The correlations for Nusselt number and Euler number deduced from this paper are well compatible with experimental data, which could provide a theoretical reference of twisted oval tube bundle for industrial applications.
