RESUMO

The dependence of water behavior on condensing steam was examined in stratified cocurrent two-phase flow in a relatively short and narrow horizontal rectangular channel. The main scope of investigation was the process of heat removal from the horizontal water surface to the bulk. A high resolution IR measurement technique was employed to measure the water temperature field. Experiments were conducted at different inflow velocities of steam (6, 8, 10, and 12 m/s) and water (0.014, 0.028, 0.042, and 0.056 m/s). The data analysis was performed by comparing calculated vertical thermal gradients of water, bulk heating power distribution, density of steam condensation mass flux, and a modified Jacob criterion. The results showed very strong dependence of condensation on the steam velocity. The optimal condensation regime was found at a steam-to-water velocity ratio of 300–400.
