Correlations for Film Condensation on a Horizontal Tube in Cross Vapor Flow

Turbulent Film Condensation on a Horizontal Elliptical Tube with Variable Wall Temperature

An analytical model has been developed for the study of turbulent film condensation from downward flowing vapors onto a horizontal elliptical tube with variable wall temperature. The interfacial shear at the vapor condensate film is evaluated with the help of Colburn analogy. The condensate film flow and local/or mean heat transfer characteristics from a horizontal elliptical tube with nonunifo...

Flow Condensation of Pure and Oil Contaminated Refrigerant HFC134a in a Horizontal Tube

Longitudinal Conduction in Cross Flow Heat Exchanger with Condensation

The deterioration of the performance of a cross flow heat exchanger with condensation due to the longitudinal conduction was investigated. For a relatively small change of wall temperature along the flow directions which was shown to be common in many applications, the energy equations were solved numerically. An iterative method was used to solve the resulting equations of the finite differenc...

Heat Transfer from a Tube Bank in Cross Flow in a Duct

An experimental investigation on heat transfer coefficient is presented from three horizontal tubes in a vertical array in a duct for 500<ReD<6000. A mass transfer measuring technique based on psychrometry chart is used to determine heat transfer coefficient. The diameter of the tubes is 11 mm each spaced 40 mm apart and in-line pitch ratio varies &#10in the range 0.055<D/W<0.22. The experimen...
