Heat Transfer Intensification in Finished Surface Pipes of Small Diameter

Abstract:

There are various methods that are used in technical practice to increase the heat transfer intensification. One of the possibilities is the use of pipes with finished surface. The type of selected surface finish of the piping influences the flow of liquids in the piping and therefore also the heat transfers in a considerable way. The issue of the hydraulic diameter of the pipe with finished surface is outlined here. The increase of transferred density of the heat flow in a pipe with finished surface in comparison with a bare pipe of the same diameter is demonstrated by a practical example.
