Abstract

We performed entropy generation analysis for a carbon nanotube (CNT) suspended nanofluid flow by a wedge with thermal radiation and convective boundary condition. The multi-wall carbon nanotube (MWCNT) with water as the base fluid was considered. Two-dimensional governing equations were transformed by similarity method into a set of coupled nonlinear ODEs and then solved analytically using optimal homotopy asymptotic method (OHAM). Moreover, solutions of these equations were further utilized in a dimensionless equation of entropy generation. The analytical results indicated that the entropy generation can be reduced by increasing radiation parameter and reducing the convection through boundaries, while nanoparticles have influence to increase the entropy production.
