Special Issue "Fluid Flow, Energy Transfer and Design"
Miguel, A. F.; Rocha, Luiz; Oechsner, AndreasFluid flow, thermodynamics and heat/mass transfer are central pillars of science and technology. They have been central to the development of our civilization because we use them to understand natural-world phenomena but also to move forward through incremental improvements in technology.
Dendritic design as an archetype for growth patterns in Nature: fractal and con...
Miguel, A. F.The occurrence of configuration (design, shape, structure, rhythm) is a universal phenomenon that occurs in every flow system. Dendritic configuration (or tree-shaped configurations) is ubiquitous in nature and likely to arise in both animate and inanimate flow systems (e.g., lungs and river basins). Why is it so important? Is there a principle from which this configuration can be deduced? In this review paper...
Fluid Flow in a Porous Tree-Shaped Network
Miguel, A. F.Tree-shaped flow networks connect one point to an infinity of points and are everywhere in Nature. These networks often own minimal flow resistance and vessel sizes obey to scaling power-laws. In this paper presents a model for fluid flow through a tree-shaped network with porous tubes. Hagen–Poiseuille flow is assumed for tubes and Darcy flow for the porous wall.
Accessing the Influence of Hess-Murray Law on Suspension Flow through Ramified ...
Serrenho, Ana; Miguel, A. F.The present study focuses on fluid flow and particle transport in symmetric T-shaped structures formed by tubes with circular and square cross-section. The performances of optimized structures (i.e., structures designed based on constructal allometric laws for minimum flow resistance) and not optimized structures were studied. Flow resistance and particle penetration efficiency were studied both for laminar and...
Flow systems, design and optimization

Special Issue “Configuration and Evolution of Flow Systems”
Miguel, A. F.; Ochsner, A,Natural and engineered flow systems have an intrinsic beauty visible for everybody. They are not amorphous – they have configurations (designs). Concepts and principles of fluid dynamics and heat transfer are fundamental to describe these systems. The ability to understand and predict things is related intimately to the scientific process. From the very early days where some basic ideas in fluid motion were int...
Special Issue “Fluid Flow: Analysis and Numerics”
Miguel, A. F.; Ochsner, A.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 ref...
Design generation and evolution of flow systems
Miguel, A. F.Special session 1: Design generation and evolution of flow systems, 7th International Conference on Diffusion in Solids and Liquids, 2011
Particle dynamics from aerosol flow
Akay, B.; Yükselentür, Y.; Miguel, A. F.; Aydin, M.Particles with different sizes are modeled under steady- state laminar flow conditions. For this purpose, a CFD numerical simulation is performed to resolve the fluid flow and particles trajectories.
Fluid Flow and Particles Transport in 3-D Packed Beds
Serrenho, A.; Miguel, A. F.A 3-D numerical study is performed to investigate the effects of periodicity (geometry) on fluid flow and particles transport through fixed beds of spheres. The following packing geometries are studied: cubic- orthorhombic simple, hexagonal, orthorhombic, rhombic-hexagonal, rhombic-pyramidal and tetragonal. The effect of the geometry both on fluid flow characteristics (permeability and inertia parameter) and tr...
