The flow of granular matter in dense regime is frequently found in both nature and industry. In nature, some examples are the erosion of river banks, the formation and migration of dunes in deserts, and landslides, for example. In industry, it occurs in pharmaceutical, agro-food, and pollution dispersion processes. Although of practical importance, dense granular flows are not well unders…
This proposal aims at developing experimental and numerical tools to understand and model particle plugs in fluid filled narrow vertical pipes, an industrial relevant situation. Taking advantage of the interaction of experimental and numerical simulations, it is proposed to test the stability of the formation of particle plugs depending on the particle friction properties and the ratio of…
Climate change impacts weather patterns and meteorological long-term data and subsequently erosion rates in deserts. Desertification is a global concern and mobile hyper-arid desert dunes threaten settlements and infrastructure of as many as one billion people worldwide. To effectively mitigate the hazard for downwind communities and infrastructure, we need to understand the dynamics of t…

The motion of solid objects (intruders) within wet granular materials is frequently found in nature and human activities. As examples, we can mention the growth of plants in waterlogged soils, animals that bury themselves at the bottom of the oceans, and drilling activities (for various purposes) in these environments. The physics behind these movements remains poorly understood and funda…
The transport of granular matter by a fluid flow is commonly found in nature and industry. In horizontal flows, the granular matter is entrained as a moving layer known as bed load. Although many studies were previously devoted to this problem, the motion of individual grains over the bed is still not fully understood. This Graduate Project (Iniciação Científica) consists in experimental …
Fluidized beds consist of suspensions of granular matter by an ascending fluid flow in a vertical tube. Devices using fluidized beds are commonly employed in industry, given their high rates of heat and mass transfers. Some examples are the combustion of coal and coating of solids. They are also used for particle classification and separation, such as happens in water treatment, and chemi…
Fluidized beds consist basically of a suspension of solid particles (grains) by an ascending fluid in a vertical tube. Devices using fluidized beds are commonly employed for the gasification of coal, given their high rates of mass and heat transfers. Uniform fluidized beds are rarely encountered in industrial applications and instabilities, such as transverse waves, bubbles, and long bubb…

Granular materials are important in our everyday lives, being frequently found in nature and industry. We find them, for instance, in mining and food industries, in the growth of roots in the ground, in the transport of sand and formation of dunes on Earth and Mars, and in the formation of craters by the impact of asteroids, to cite but a few examples. Given their importance, we have been…
Fluidized beds are generally used when an increase in mass and/or heat transfers is desired, being commonly found in pharmaceutical (tablet granulation), mining (sediment separation and classification), and sanitation (water treatment) processes, for instance. With the increasing demand for minerals and water treatment worldwide, improving these processes is crucial to achieving economic …
From the movement of animals and machines on and within granular matter to the penetration and collision of solid objects in the sand, the displacement of a solid body (intruder) within a granular medium is ubiquitous in nature and human activities. Furthermore, global warming is leading to the creation of more and more desert areas on the planet. The delivery and transport of goods in th…
The transport of particles by turbulent flow is quite common in nature and industry. Some examples are the transport of sand by wind in deserts and by the water in rivers and oceans, the transport of sand in canals and dredging system and the pneumatic conveying of grains in the food industry. In horizontal flow, this transport can occur as a moving layer of grains, known as a bed load. U…
The transport of solid particles as bed load by a fluid flow is widely encountered in industrial and environmental applications. For example, it can be found in rivers, oceans, petroleum pipelines, sewer systems, and dredging lines. Bed load transport is a kind of dense granular flow and it is known to segregate grains by size and by shape. Understanding the dynamics between the granular …
