Numerical investigation of heat transfer enhancement by carbon nano fibers deposited on a flat plate

Numerical simulations of flow and heat transfer have been performed for flow over a plate surface covered with carbon nano fibers (CNFs). The CNFs influence on fluid flow and heat transfer has been investigated. Firstly, a stochastic model for CNFs deposition has been explained. Secondly, the lattic...

Description
Summary:Numerical simulations of flow and heat transfer have been performed for flow over a plate surface covered with carbon nano fibers (CNFs). The CNFs influence on fluid flow and heat transfer has been investigated. Firstly, a stochastic model for CNFs deposition has been explained. Secondly, the lattice Boltzmann model for simulating fluid flow and heat transfer is described. Finally, results from calculations for the heat transfer are presented. The results show substantial heat transfer enhancement for a densely covered surface with CNFs of varying length. From a detailed analysis of the results it is concluded that the enhancement is caused by boundary layer regeneration.
