Abstract

This study investigates the thermal-hydraulic characteristics of helically coiled tube heat exchangers applied in high temperature gas reactors. In the heat exchanger, the high-temperature helium and the low-temperature water flow through the shell side and the coiled tube, respectively. Three turbulence models are incorporated with Navier-Stokes equations in the numerical simulations: realizable k-ε, low-Reynolds k-ε and Reynolds stress. Existing experimental data on the Nusselt (Nu) number validate the present CFD simulations using these turbulence models. © 2013 Elsevier B.V. All rights reserved.
