Convection in Ferro-Nanofluids: Experiments and Theory
This book covers the experimental and theoretical study of convection in non-isothermal ferro-nanofluids (FNFs). Since FNFs are not transparent and magnetic fields are very sensitive to the shape of the boundary between magnetic and nonmagnetic media, special flow visualization techniques based on the use of thermo-sensitive liquid crystal films, infrared cameras, as well as local and integral temperature sensors are discussed in the book. This book considers several major configurations of convective chambers and the applied magnetic field. For each of them, the stability boundaries are determined theoretically and experimentally. The physical types of dominant instabilities and the characteristics of their interactions are subsequently established using linear and weakly non-linear hydrodynamic stability analyses and elements of bifurcation theory. The book also discusses the potential of using magnetically controlled ferro-nanofluids as a heat carrier in situations whereheat removal by natural convection is not possible due to the lack of gravity (orbital stations) or extreme confinement (microelectronics). Researchers and practitioners working in the areas of fluid mechanics, hydrodynamic stability, and heat and mass transfer will benefit from this book.
Heat Energy Recovery for Industrial Processes and Wastes
This book provides new techniques for recovering exhaust heat from gas turbines, natural gas combined cycle power plants, biomass boilers, and waste heat recovery from compost and wastewater treatment plants The book provides modeling for the study and comparison of combined cycle power plants with a heat recovery boiler of three pressure levels with reheating, inserting a technological improvement of solar hybridization and partial regeneration in the gas turbine. It assesses the environmental impacts and economic sustainability associated with these improvements. In addition, it proposes emissions minimization, with exhaust gas recirculation (EGR), and emissions treatment with a CO2 capture plant (CCP) and combined cycle power plant. Finally, it provides new insights into heat recovery from compost and exhaust gases recovery from wastewater treatment plants.

In the present book, nanofluid heat and mass transfer in engineering problems are investigated. The use of additives in the base fluid like water or ethylene glycol is one of the techniques applied to augment heat transfer. Newly, innovative nanometer-sized particles have been dispersed in the base fluid in heat transfer fluids. The fluids containing the solid nanometer-sized particle dispersion are called "nanofluids." At first, nanofluid heat and mass transfer over a stretching sheet are provided with various boundary conditions. Problems faced for simulating nanofluids are reported. Also, thermophysical properties of various nanofluids are presented. Nanofluid flow and heat transfer in the presence of magnetic field are investigated. Furthermore, applications for electrical and biomedical engineering are provided. Besides, applications of nanofluid in internal combustion engine are provided.
