Assistant Professor in the University of São Paulo (USP) at São Carlos School of Engineering (EESC), allocated at the Department of Mechanical Engineering since 2023. I have a degree in Mechanical Engineering from the State University of Campinas - UNICAMP (2012) and a PhD in Mechanical Engineering from the State University of Campinas - UNICAMP (2017). I worked as a Product Engineer in the automotive company Magneti Marelli Sistemas Automotivos (outsourced) from 2013 to 2018. From 2018 to 2020, I worked as a Research Engineer by the Institut de Radioprotection et de Sûrété Nucléaire (IRSN) and Post-doctoral Fellow by the Université de Lorraine in Nancy, France. From 2020 to 2021, I worked as a Research Engineer at Institut de Recherche Technologique Matériaux, Métallurgie et Procédés (IRT M2P) with Laboratoire Énergies & Mécanique Théorique et Appliquée (LEMTA) and Institut Jean Lamour (IJL) in the Université de Lorraine in Nancy, France. In 2022, I was a Guest Researcher at São Carlos School of Engineering, University of São Paulo, Brazil (EESC/USP). I am Responsible Researcher of a FAPESP Young Investigator project. Research experience in the area of Heat Transfer and Fluid Mechanics, with emphasis on spray and jet cooling and droplet impact. In the industry, I have experience in Product Development, with an emphasis on Fuel Heating Systems. Main themes: Droplets, Cooling, Optical Techniques, Thermal-hydraulics in nuclear reactor, Fuel heating, Solar Heating, Thermal and Fluids, Phase Equilibrium, Product Development.

The impact of droplets on heated surfaces is a fundamental phenomenon in thermal cooling processes with relevant applications in the metallurgical, nuclear, automotive, and electronic industries. As part of the ongoing Young Investigator project at LETeF (EESC-USP), we propose the granting of two undergraduate research scholarships (Iniciação Científica) for complementary investigations a…
Equipment for dynamic and thermal characterization of fluids using Shadowgraphy and Planar Laser-Induced Fluorescence (PLIF) techniques. The first technique allows measurements of shape, size and velocity (through double pulses like the PIV technique), while the second allows measurements of the temperature field by the ratio of the light intensity of two different spectral bands. The bud…
Droplets and sprays impact onto heated walls have drawn much attention from the Thermal Engineering community because of its many applications that allow uniform and efficient heat exchange, especially for the cooling of high-temperature parts. However, most of the experimental studies in the literature only visualize the droplets impact or use intrusive measurement methods. This lead to …
The increasing heat dissipation rates in devices require using efficient cooling methods, like microchannels heat sinks and spray cooling systems that are capable of reaching dissipated heat fluxes of several MW/m2. In the case of sprays, to improve this kind of cooling system, it is important to understand in more detail the dynamics and the heat transfer process during the droplet impac…
The project for creating a map of droplet coalescence using optical techniques aims to investigate the phenomenon of droplet coalescence, a process in which two droplets merge during impact. Understanding this behavior is essential to improve spray cooling, a technique widely used in fields such as metallurgy, aeronautics, automotive, nuclear, and electronics. This method stands out for i…
Spray cooling is a widely used and highly effective technique in industrial applications. This process plays a crucial role in a range of operations, such as tempering and other heat treatments, where precise temperature control is essential to achieve enhanced mechanical properties in treated parts. Despite its widespread application, important theoretical gaps persist in understanding t…
The use of combined optical techniques is an important step forward to better characterize complex thermal-hydraulic phenomena. For example, for droplet impact studies, using simultaneously Shadowgraph (SDG), Laser-Induced Fluorescence (LIF), Infrared Thermography (IRT) and Total Internal Reflection (TIR) allows measuring, at the same time, the droplet shape (SDG), velocity (SDG) and temp…
The use of sprays is common in several industrial areas: in the metallurgical sector, for the cooling of metal parts, in the manufacture of sponges, for the application of abrasives for surface coating, or in the manufacture of foods, such as powdered milk. Therefore, it is common for scientific studies in this area to use previously defined average parameters, such as the average droplet…
At the moment the application of sprays is already commonly carried out in the most diverse areas of the industry. In internal combustion engines, for example, it is common to use a fuel injection system using sprays, in order to increase the fluid atomization and avoid adhesion and contact with the walls of the combustion chamber. Another important application is based on surface cooling…
Droplet impact on heated walls is still largely studied in the literature because of its many applications in the industry, like metallurgy, nuclear energy, automotive, electronics, and others. Even though much has advanced in the past decades, few investigations used combined optical techniques to measure all the thermal and fluid dynamics processes before, during, and after the droplet …

Although sprays are common in many industrial applications, analyzing them with average parameters is insufficient. A more precise method is to study single droplets in a controlled lab environment. However, more research on how droplets impact heated surfaces is still required. Aiming to investigate the formation, characterization, and quantification of secondary droplets - including the…
The impact of droplets on solids is a phenomenon widely present in various areas of engineering, showing different behaviors depending on the type of surface and the thermal conditions involved. In aeronautics, for example, water droplets can impinge an aircraft during ight, especially in rainy conditions, representing a signicant risk. This can compromise visibility in the cabin and, in …
Droplet impact has garnered significant interest in academia due to its numerous industrialapplications, such as steam turbines, falling film evaporators, internal combustion engines,and spray cooling. Despite the broad range of applications, the heat transfer processes betweendroplets and heated surfaces are not yet fully understood, largely due to the numerousvariables involved, such as…
Droplet impact on surfaces is a process found in various engineering applications, such as metallurgy, nuclear reactors, internal combustion engines, propulsion turbines, cooling of electronic components, among others. To better characterize the hydrodynamic and thermal processes during the impact of one or more droplets on a heated surface, a research project was initiated in 2022 with t…
