After a tumultuous career as a revolutionary in Ireland and an ultra-conservative Catholic in the United States, Thomas D'Arcy McGee moved to Canada in 1857, where he became a force for moderation and the leading Irish Canadian politician in the country. Determined that Canada should avoid the ethno-religious strife that afflicted Ireland, he articulated an inclusive, broad-minded nationalism based on generosity of spirit, a willingness to compromise, and a reasonable balance between order and liberty. To realize his vision, McGee became a strong supporter of the "new northern nationality." A spellbinding orator who emerged as the youngest and most intellectually gifted of the Fathers of Confederation, he fought what he saw as the atavistic and intolerant elements of Canadian life - the Orange Order, with its strident anti-Catholicism; the opponents of separate schools, whom he viewed as enemies of minority rights; and above all the Fenian Brotherhood, with its dreams of revolutionizing Ireland and annexing Canada to the United States. Convinced that compromise with Fenianism was impossible, he set out to destroy the movement through a strategy of confrontation and polarization - channeling his earlier extreme tendencies in the service of moderation and attempting to reduce the influence of Fenianism within his own community. In the process, he alienated many of his former supporters, who came to regard him as a traitor who sacrificed the cause of Irish nationalism on the altar of personal ambition. On 7 April 1868, McGee was assassinated on the doorstep of his Ottawa boarding house. As someone who took an uncompromising stand against militants within his own ethno-religious community, and who attempted to balance core values with minority rights, McGee has become increasingly relevant in today's complex multicultural society.

Subsurface flow problems are inherently multiscale in space due to the large variability of material properties and in time due to the coupling of many different physical processes, such as advection, diffusion, reaction and phase exchange. Subsurface flow models still need considerable development. For example, nonequilibrium effects, entrapped air, anomalous dispersion and hysteresis effects can still not be adequately described. Moreover, parameters of the models are difficult to access and often uncertain. Computational issues in subsurface flows include the treatment of strong heterogeneities and anisotropies in the models, the efficient solution of transport-reaction problems with many species, treatment of multiphase-multicomponent flows and the coupling of subsurface flow models to surface flow models given by shallow water or Stokes equations. With respect to energy and the environment, in particular the modelling and simulation of radioactive waste management and sequestration of CO2 underground have gained high interest in the community in recent years. Both applications provide unique challenges ranging from modelling of clay materials to treating very large scale models with high-performance computing. This book brings together key numerical mathematicians whose interest is in the analysis and computation of multiscale subsurface flow and practitioners from engineering and industry whose interest is in the applications of these core problems.

Fluid interfaces are promising candidates for confining different types of materials - e.g., polymers, surfactants, colloids, and even small molecules - and for designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the Physico-chemical bases underlying the formation of layers at fluid interfaces, as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and dynamics features in the interfacial systems, which are far from those conventionally found in the traditional materials. This Special Issue is devoted to studies on fundamental and applied aspects of fluid interfaces, trying to provide a comprehensive perspective on the current status of the research field.

This book presents a collection of works published in a recent Special Issue (SI) entitled “Computational Fluid Dynamics”. These works address the development and validation of existent numerical solvers for fluid flow problems and their related applications. They present complex nonlinear, non-Newtonian fluid flow problems that are (in some cases) coupled with heat transfer, phase change, nanofluidic, and magnetohydrodynamics (MHD) phenomena. The applications are wide and range from aerodynamic drag and pressure waves to geometrical blade modification on aerodynamics characteristics of high-pressure gas turbines, hydromagnetic flow arising in porous regions, optimal design of isothermal sloshing vessels to evaluation of (hybrid) nanofluid properties, their control using MHD, and their effect on different modes of heat transfer. Recent advances in numerical, theoretical, and experimental methodologies, as well as new physics, new methodological developments, and their limitations are presented within the current book. Among others, in the presented works, special attention is paid to validating and improving the accuracy of the presented methodologies. This book brings together a collection of inter/multidisciplinary works on many engineering applications in a coherent manner.
