Fluid dynamics is a broad, interdisciplinary field that touches almost every aspect of our daily lives, and it is central to science and engineering. Therefore, it is one of the most challenging and exciting fields of scientific activity. The complexity of the subject and the breadth of the applications are inspiring advances in analytical, numerical, and experimental techniques. This special issue contains refereed papers that covers analytical, numerical, and experimental studies. The shape and structure of the issue sprang from the struggle for better performance in both engineering and nature. This idea is the basis of the new constructal theory employed by Rocha et al. to optimize the geometry of thin perforated plates submitted to elastic buckling. Friedler et al. studied combined mass diffusion and chemical reaction (i.e., nickel–aluminum reaction) based on a lattice Monte Carlo method. This methodology has the advantage of very fine resolution in the geometry, which is essential in moving boundary problems. Brito et al. propose an adaptive numerical algorithm that conjugates a method of lines based on finite-difference space discretization, with a collocation scheme based on increasing level dyadic grids, to solve thermite combustion propagation. The finite-volume method is one of the most versatile discretization techniques used in computational fluid dynamics. Based in this method, Sheikhzadeh et al. study laminar natural convection of a Cu–H2O nanofluid between two horizontal concentric cylinders with radial fins attached to the inner cylinder, and Abbasian Arani analyzes buoyancy-driven natural convection in a nanofluid-filled square cavity induced by an arc-shaped heated baffle. Finally, Corral-Bustamante et al. present a model to predict the transport of mass (energy) through a metric tensor in the Planck scale.
