Correlations and Data for Heat Transfer Coefficients

2016
The problems of heat flow with convection, discussed in the preceding chapter, pertain to simple systems with laminar flow. Despite the simplicity of laminar flow problems, they should not be underestimated. Many simple solutions have been applied to real systems with approximating assumptions and, besides, the simpler systems provide models for ...

Heat‐transfer coefficient of condensing vapours

Journal of Applied Chemistry, 1951
AbstractThe original method employed by Wilson to eliminate the use of thermocouples embedded in the tube wall in evaluating the heat‐transfer coefficient of the condensing vapours is not fundamentally sound. A modified method on a more rigorous basis is presented.It has been demonstrated theoretically that the heat‐transfer coefficient of a condensing

Heat‐transfer coefficients for industrial gases

Journal of Applied Chemistry, 1952
AbstractIn order to find out the correct size required for heat exchangers, waste‐heat boilers, gas coolers, etc., heat‐transfer coefficients are needed. Although the available literature provides us with the most recent formulae for these coefficients it is nevertheless difficult to assemble all the technical data of the required dimensions.

The heat transfer coefficient for flow in a pipe

International Journal of Heat and Mass Transfer, 1961
Abstract The paper records new data on the local heat transfer coefficient in a straight pipe remote from the entrance. Water and air were used, at Reynolds numbers from 300–100,000; the pipes were horizontal, of seven different diameters from 1.27 to 5.08 cm. Temperature differences were small.

Heat Transfer Coefficient and Physical Properties

2014
No matter how sophisticated the calculation method, the results can be reliable only if accurate information is supplied. The main inputs for a freezing problem, apart from the product geometry, are the heat transfer coefficient and the food’s thermal properties: freezing point, calorimetric properties, thermal conductivity and density.
