Sinopsis

Work on pressure losses in banks of porous tubes of sintered bronze, which permit part of the air flowing across them to be sucked away to simulate the mass transfer in condensers, has been carried out with in-line square, equilateral triangle, and triangular with constant-gate arrays. The bank was up to seven rows deep, with seven tubes across the flow, having transverse pitch-diameter ratios of 1.25.
Results are presented in terms of pressure coefficients and friction factors, for ranges of Reynolds number and mass extraction typical of vacuum and process condensers. They are compared with published and the authors' own no-suction correlations or results.
