TOPIC: Modeling of Nanofluids Transport and Applications

This keynote lecture focuses on the heat transfer characteristics of a new innovative class of fluids called nanofluids. The importance of nanofluids in industrial, engineering and scientific applications is highlighted. Models for nanofluids properties are given and the mechanisms of potential heat transfer enhancement are reported. Nanofluids’ model applications to various problems such as mixed convection in single and double lid-driven inclined/non-inclined square cavities with constant and variable viscosity effects, mixed convection in a composite (porousmedia/nanofluid) cavity with inner rotating cylinder, natural convection in trapezoidal enclosures solar collectors, conjugate heat transfer in cavities with conducting objects, melting of nanoparticles enhanced phase-change materials in enclosures, fluid-structure interaction with hybrid nanofluids and others are covered. Also, various aspects of boundary layer flows of nanofluids in porous and nonporous material considering nanoparticle size, shape and type, base fluid type and working temperature for the cases of forced and natural convection are discussed. The conditions for heat transfer enhancements are discussed.
