Numerical Simulation of Heat and Mass Transfer in Fluid Flow

Computational Fluid Dynamics has become an indispensable tool in the scientific research as well as in the modern engineering design and development. The increasing computer power during the last decades allowed for more and more detailed numerical simulations, which deepened the insight and understanding of physically highly complex flow problems involving complicated geometries, chemical reactions, phase change, etc.

Nanofluid, which is a mixture of nano-sized particles (nanoparticles) suspended in a base fluid, is used to enhance the rate of heat transfer via its higher thermal conductivity compared to the base fluid. Due to this enhancement of the material properties, nanofluids are widely used in our life such as in transportation (engine cooling and vehicle thermal management), electronics cooling, nuclear systems cooling, heat exchanger, biomedicine, heat pipes, fuel cell, Solar water heating, etc.

In this seminar, we shall present some fluid models, following [1] and [2], and then we will discuss applications to nanofluids, based on references [3], [4], and [5].
