THE PERFORMANCE OF AN EXPERIMENTAL CONDENSER
要約
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.
