Lagrangian Particle Tracking in CFD

Lagrangian Particle Tracking (LPT) is a powerful technique used in Computational Fluid Dynamics (CFD) to simulate the behavior of individual particles as they move through a fluid system. In LPT, each particle is treated as an individual entity that interacts with the surrounding fluid, and its motion is tracked over time. This technique can be used to model a wide range of phenomena in areas such as engineering applications: simulating the mixing of fuel droplets in the combustion chamber of propulsion systems; environmental applications: simulating the dispersion of pollutants emerging from factories formation and growth of raindrops, and transport of atmospheric aerosols; medical applications: simulating the drug delivery to pulmonary systems and deposition of blood cells in the human body.

Particulate Raleigh Benard Convection

Rayleigh-Bénard Convection (RBC) refers to the flow of fluids when heated from below and cooled from above. Particulate flows, on the other hand, refer to the flow of fluids that contain solid particles. In RBC, particulate flows can have several applications in various fields:In industry, particulate flows in RBC can be used to improve the efficiency of heat transfer in industrial processes. For example, the use of nanoparticle suspensions in RBC can enhance the heat transfer in various industrial applications, such as electronics cooling, energy storage, and thermal management. In medical applications, particulate flows in RBC can be used to study blood flow in the body.
