The models have been adapted from the literature for a narrow high aspect ratio geometry using the measurements obtained in a companion paper. Three - dimensional computational results have been compared with cross - section averaged and line - averaged void fractions measured with a gamma densitometer, and local void fraction measured with a hot - film anemometer. These comparisons have been made over a wide range of flow inlet conditions, wall heating and system pressure. Comparisons are found to be good when the flow is bubbly, but at high void fractions, where the flow is churn - turbulent or annular, the two - field modeling approach does not perform adequately. This result emphasizes the need for multiple field modeling. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
