A One-Dimensional Model for Nanofluid Flow with Nanoparticle Aggregation in Long Pipes

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

This study presents a one-dimensional model for nanofluid flow and heat transfer with simultaneous nanoparticle aggregation in long pipes. The model is governed by mass, momentum, energy and nanoparticle species conservation equations with appropriate initial and boundary conditions. Nanoparticle aggregation is accounted for using a geometric population balance approach. Compared to existing models, the presented model requires less computational efforts in particular when applied to long pipes as it employs a one-dimensional approach and geometric population balance approach (compared to a regular population balance approach). The model is applied to investigate heat transfer performance of nanofluid in pipes. Various parametric studies are conducted.
