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…
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…
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…
Granular media are formed by a significant amount of solids (grains), and they are abundant on the Earth surface: 20% of emerged lands consist of sand and other grains. In addition, the world production of grains is of approximately 10 billions tons (metric) by year, and their processing consumes roughly 10% of all the energy produced worldwide. The transport of granular matter by gravity…

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…
The fluidization and transport of granular matter by a fluid flow in turbulent regime are frequently found in nature and industry. Some examples are the aeolian transport of sand in deserts, transport of sand by water in rivers, oceans and open channels, sand transport in dredging and sewer systems, fluidization of grains for gaseification of solid fuels, and pneumatic transport of grains…
The motion of a solid intruder in granular media is commonly found in nature and human activities. Some examples are the motion of animals and machines over and within granular matter, penetration and impact of solid objects in sand, and geospace applications such as the landing of space probes on other planets. The physics behind the dynamics of these motions remains poorly understood an…

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…
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 …
The transport of sediments by turbulent flows is commonly found in both nature and industry. Some examples are the transport of sand in deserts, rivers and oceans, sediment transport in channels, dredging lines and sewer systems, and pneumatic and hydraulic conveying of grains in food industry. For horizontal flows, there is usually the formation of a granular bed whose topmost layers are…

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 …
