摘要

The present lecture reviews some recent fundamental research undertaken at the Laboratory of Heat Transmission and Technology of Heat, Federal University of Rio de Janeiro, related to energy efficiency improvement by heat transfer enhancement in laminar channel flow. Three complementary research lines were explored, dealing with modifications of the base fluid with the dispersion of metallic oxide nanoparticles (nanofluids), with the analysis of conjugated heat transfer effects on convection in microchannels, and with the study of heat transfer enhancement in wavy wall ducts at the micro-scale. All the theoretical work was performed by making use of mixed symbolic-numerical computation (Mathematica 7.0 platform) and a hybrid numerical-analytical methodology (Generalized Integral Transform Technique - GITT) in accurately handling the governing partial differential equations for the heat and fluid flow problem formulations. Experimental work was also undertaken and sample results, where applicable, are presented to verify the proposed models. The aim is to illustrate detailed modeling and robust simulation leading to explanations of a few controversial aspects in laminar forced convection, and providing the adequate tools for the analysis of compound enhancement techniques, towards the development of optimally enhanced heat transfer solutions.
