Constrained Direct Optimisation of the Geometrical Parameters of a Twisted-Tape for Laminar Flow in a Circular Tube
(2021-01-01)
Increasing heat transfer in heat exchangers remains an important research topic for industrial and residential applications. The usage of passive techniques remains a reference due to the lower costs, however, increasing ...
Two-phase flow patterns and pressure drop inside horizontal tubes containing twisted-tape inserts
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This paper presents an experimental study on two-phase flow patterns and pressure drop of R134a inside a 15.9 mm ID tube containing twisted-tape inserts. Experimental results were obtained in a horizontal test section for ...
Simulação numérica de trocadores de calor multitubulares equipados com fitas helicoidais externamente aos tubos
(1998-03-01)
Classical shell-and-tube heat exchangers are usually equipped with segmental baffles. These baffles serve two basic functions: (a) they provide tube supports, thereby preventing or reducing mechanical problems, such as ...
