The dynamic of complex fluids like blood, epoxies, brain fluid, colloidal suspensions and industrial fluids are analyzed in the field of Computational Fluid Dynamics of micropolar fluids. This field demands more work to unhide the hidden features of these fluids particularly when these fluids flow in complex geometries. This book was written to investigate these features. One of the dominant features of this book is that it comprises novel methods namely the “Modified Adams-Bashforth temporal scheme”, the “Runge-Kutta temporal scheme” and the “Adam-Bashforth temporal Fourier series method”. Furthermore the text is amply illustrated with graphical and tabular simulations to enable the reader to comprehend the subject with ease. In order to highlight micropolarity effects, the results for the simple Newtonian fluids are also included, which makes the book interesting.
