In the present study, an attempt has been made to summarize and analyze the results of an
examination of the air-side performance of spiral (or helical) fin-and-tube heat exchangers …

This investigation conducted experiments on the gas-side performance of serrated spiral fin-
and-tube heat exchanger with staggered layouts. The number of tube rows is 10 under the …

Abstract A Computational Fluid Dynamics (CFD) model capable of predicting heat-transfer
and pressure-drop performance of finned-tube bundles in cross flow is presented. Three …

We propose a method for the estimation of the overall heat transfer coefficient to/from a fluid
in a cylindrical pipe at high Peclet numbers from/to a medium with unknown temperature …

The combined cycle power plant consists of topping cycle, bottoming cycles and heat
recovery steam generators (HRSGs) as the integral systems. The main focus of this work is …

This study presents a new approach on the heat transfer enhancement of annular fins with
constant thickness using functionally graded materials. The thermal conductivity of the …

Assessment of the thermal characteristics of materials in heat exchangers with longitudinal
fins is performed in the case where a conventional homogeneous material of a longitudinal …

A numerical analysis is carried out in a small finned tube bank for several cutoff angles (30°,
45°, 60°, and 90°) at the rear part of helical segmented-tubes. Numerical simulations are …

Using the complementary functions method, a general solution for the one-dimensional
steady-state heat conduction equation for the fin together with the boundary conditions …

Spiral tubes have been reported to be able to improve the heat transfer performance of the
fluid flowing through, which is traditionally believed to be caused by the helix structure. In …
