Concept of a measurement and test station to determine linear pressure drop and the heat transfer coeffcient of internally ribbed tubes

Majewski K.

Journal of Power Technologies

2013

Vol. 93, nr 5

340--346

This paper presents applications for internally finned tubes in boilers designed for supercritical parameters. It outlines the characteristic dimensions of a tube used for the construction of a test station to determine the heat transfer coeffcient and linear friction losses pertaining to flows inside internally ribbed tubes. Theoretical dependencies used for predicting the heat transfer coeffcient and linear friction losses are presented herein. The paper ends with a description of the test station.
