Condensation of Vapors on a Horizontal Tube

Condensers

“…[18][19][20][21][22][23]. A number of other correlations have been developed for this regime; see, e.g., Refs.…”

“…(11.4) Akers and Rosson [19] developed a correlation for convective condensation in horizontal tubes that is valid for both laminar and turbulent condensate films. It utilizes a vapor-phase Reynolds number, Re à V , defined as follows: (11.28) 70,000 lb/h of saturated cyclohexane vapor will be completely condensed at 196 F and 20 psia.…”

Heat Transfer Coefficients for the Condensation of Mixed Vapors of Turpentine and Water on a Single Horizontal Tube

“…The work of Baker and Mueller (1) and Langen (4) showed that the temperature variation around the perimeter of a tube on which condensation was taking place could cause serious errors in heat transfer coefficients determined by measuring the tube-wall temperature at one point on the perimeter of the tube. These authors showed that no single point could be depended on to give an average value of the tube-wall temperature.…”

Film Coefficient of Condensing Vapor

“…There is likely to be disturbance of the fluid film on the tube surface due to irregularities; however, with the present advanced techniques it is probable that the surface can be smoothed properly. The introduction of a foreign metal in the tube wall will be likely to disturb the flow of heat through 1 Present address, Monsanto Chemical Company, St, Louis, Mo. 2 Present address, Fouke Fur Company, St. Louis, Mo.…”
