The performance of heat exchangers can be improved to perform a certain heat-transfer duty
by heat transfer enhancement techniques. In general, these techniques can be divided into …

Heat transfer and pressure drop correlations for fully developed laminar Newtonian fluid flow
in curved and coiled circular tubes are reviewed. Curved geometry is one of the passive …

Narrow residence time distributions (RTDs) are desirable in many chemical engineering
processes. However, when a system operates in the laminar flow regime, significant fluid …

Flatter velocity profiles and more uniform thermal environments are extremely desirous
factors for improved performance in flow reactors and heat exchangers. One means of …

Double-pipe heat exchangers have been widely used in various industries, and the efficient
design of these heat exchangers has received a significant research impetus. Chaotic …

The heat transfer characteristics and the performance of a spiral coil heat exchanger under
cooling and dehumidifying conditions are investigated. The heat exchanger consists of a …

This work presents an experimental and numerical study of pulsated Dean flow, three-
dimensional pulsatile flow in a curved pipe. The numerical study is performed by CFD code …

In this paper, we present an innovative sine-helical heat exchanger whose channel
geometry consists in a combination of a helically coiled geometry and a sine-wave …

In this article incompressible viscous flow in a helical annulus is studied numerically. A
second order finite difference method based on the projection algorithm is used to solve the …
