Abstract
Purpose - The purpose of this paper is to carry out a numerical investigation to study forced convection for a tube with fins on the inner and outer surfaces with water as the base fluid and adding particles of CuO to have a nanofluid. Design/methodology/approach - Three geometries are designed by using Solid Works and the number of inside fins is 20 with height 6 mm and thickness 1mm. The number of outside fins is 20 with height 12mm and thickness 1 mm. The length of the tube is 1,000mmand the inner and outer diameter is 26 and 28mm, respectively. The annular diameter is 60mm. The geometries are imported to Gambit where the mesh is chosen and the boundary conditions are specified. The commercial software package Fluent version 14.0 has... (More)

The geometries are imported to Gambit where the mesh is chosen and the boundary conditions are specified. The commercial software package Fluent version 14.0 has been used to numerically solve the governing equations for the three cases. Findings - The temperature contours for the three models at different air velocities, i.e., 5, 7.5 and 10 m/s and water velocities 0.8, 1 and 3 m/s have been investigated. The enhancement of heat transfer by using CuO nanoparticles has been investigated at different nanofluid concentrations. Originality/value - In this paper, a numerical study is presented to analyze internal and external longitudinal finned tubes with water inside and air outside, with and without nano CuO particles.
