Preface

In this book, readers are provided with different applications of nanofluid for heat transfer enhancement. Various methods can be used for the simulation of nanofluid hydrothermal behavior. In this book, we present the application of new numerical and semianalytical methods for the simulation of nanofluid flow and heat transfer. Additionally, several good codes for these methods are provided. Influences of external forces, such as buoyancy, Lorentz, Kelvin, and Coulomb forces on nanofluid hydrothermal characteristics are considered. Both single-phase and two-phase models are used in different examples. This text is suitable for senior undergraduate students, postgraduate students, engineers, and scientists.

Chapter 1 of this book deals with the essential fundamentals of nanotechnology. The different models for simulation of nanofluid are discussed. Further, recent publications regarding nanofluids are reviewed in this chapter. Chapters 2 and 3 deal with nanofluid natural and forced convective heat transfer. Several examples are presented in these chapters. Effect of thermal radiation on nanofluid flow and heat transfer is presented in Chapter 4. The thermal radiation has an important role in the overall surface heat transfer when the convection heat transfer coefficient is small. Chapter 5 gives a complete account of nanofluid hydrothermal treatment in the presence of an electrical field. Combination of an active method (electrohydrodynamic method) with an innovative passive method (nanotechnology) is considered in this chapter. Influence of Coulomb forces on nanofluid hydrothermal characteristic is examined. Several examples included in Chapters 6 and 7 give the reader a full account of the theory and practice associated with the magnetohydrodynamics and ferrohydrodynamics. Both constant and variable magnetic fields are considered in different examples. Chapter 8 deals with the application of nanofluid in the solidification mechanism. In this chapter, the method of producing nanoenhanced phase change material (NEPCM) and using fin with suitable array, which to accelerate the solidification process, are presented. FLEX PDE software (standard Galerkin finite element method) is used in this chapter. Chapter 9 discusses nanofluid flow and heat transfer in porous media. Nanofluid flow in porous tubes or channels has been under considerable attention in this chapter because of its various applications in transpiration cooling boundary layer control. Several sample codes of new numerical (FEM, CVFEM, and LBM) and semianalytical methods (ADM, HPM, DTM, OHAM, HAM, and AGM) are presented in the appendix. The readers will be able to extend these codes and solve all of the examples presented in this book.
