Variables examined were in the following ranges: pressure, 2 inHg abs; steam loads, 400-4000 Ib/h; inlet steam to coolant temperature differences, 15-30 degF; coolant velocities, 3-7 ft/s; inlet air concentrations, 0.02-6 per cent. Experimental observations include the heat flux on the whole and on certain tubes in the bundle and variations of non-condensable gas content, pressure and temperature throughout the tube nest.
Comparison is made between theory and experiment and includes examination of the influence of non-condensable gas distribution in the nest, and of vapour by-passing the nest. It is concluded that precise prediction of performance of tube nests requires the solution of the complex two-dimensional forced convection and diffusional flow patterns over the tube nest cross-section.
