This paper presents a unified numerical method able to address a wide class of fluid flow problems of engineering interest. Arbitrary fluids are treated specifying totally…

Direct numerical simulation of turbulent heat transfer in a square duct

M. Piller, E. Nobile

The results from a direct numerical simulation (DNS) of turbulent, incompressible flow through a square duct, with an imposed temperature difference between the horizontal walls…

Influence of a magnetic field on liquid metal free convection in an internally heated cubic enclosure

Michele Ciofalo, Fabrizio Cricchio

The buoyancy‐driven magnetohydrodynamic flow in a cubic enclosure was investigated by three‐dimensional numerical simulation. The enclosure was volumetrically heated by a uniform…

Natural convection in vertical channels with an auxiliary plate

Assunta Andreozzi, Oronzio Manca, Vincenzo Naso

Research on natural convection in open channels is very extensive due to its role in many engineering applications such as thermal control of electronic systems. In this paper, a…

Convective heat and mass transfer in wavy finned‐tube exchangers

G. Comini, C. Nonino, S. Savino

The paper adopts a simplified two‐dimensional approach to deal with convective heat and mass transfer in laminar flows of humid air through wavy finned‐tube exchangers. The…

Numerical analysis of forced convection in plate and frame heat exchangers

G. Croce, P. D’Agaro

A three‐dimensional numerical investigation of flow field and heat transfer in sine‐wave crossed ducts is presented. Numerical simulations are carried out using a finite element…
