Modelling of Thermal Stress in Yb:YAG to Quantify Depolarisation in a Nanosecond 10 J, 100 Hz Laser
The high heat loads intrinsically associated with high-energy, high repetition rate laser systems require sophisticated thermal management analyses to minimise the impact of thermal effects on optical performance. Non-uniform heat deposition in optical elements can lead to the onset of ... Per saperne di più
Modeling and Multiphysics Simulation of the Directed Energy Deposition Additive Manufacturing
In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... Per saperne di più
Thermal Battery Simulation Models: Evaluating Levels of Abstraction and Geometric Resolution
The accurate modeling and simulation of battery cells are crucial for the optimization and design of efficient energy storage systems. The choice of an appropriate battery simulation model heavily depends on the specific problem being investigated. This poster presents a comparative ... Per saperne di più
Modelling the Composition Gradient in Ni-Mn-Ga Single Crystal Grown by Floating Zone Method
Re-crystallisation of Ni-Mn-Ga Heusler alloys in a floating zone (FZ) optical furnace is a complex problem that depends not only on the compositions of the master alloy and a seed crystal but on the growth speed and evolution of the molten zone shape during the crystal growth process. We ... Per saperne di più
Methanation in Catalytic Reactor
Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ...

Modeling of Iron Ore Reduction Above the Cohesive Zone of the Blast Furnace
The blast furnace shaft is a huge counter flow reactor in which heat and mass exchange play a significant role in its mathematical modelling. The heat exchange model is already available in COMSOL Multiphysics® via the Local Thermal Non-Equilibrium interface. This multiphysics coupling ... Per saperne di più
Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit
When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... Per saperne di più
Monte Carlo Simulation to Model Natural Variability in Food Drying
Convective drying of fruits and vegetables is a widely used preservation method and serves to reduce food waste, to make them available off-season and to reduce weight-related transport costs. However, the high energy consumption and impact of the process set-up and process settings on ... Per saperne di più
Indoor Thermal Analysis of a Storehouse
The aim of this study is to evaluate the airflow thermal distribution inside a storehouse in different operational conditions. A warehouse of 12,600 m3 in volume is considered for fluid-dynamical and thermal analysis. Coupled Navier-Stokes and energy equations are solved considering or ... Per saperne di più
A Framework for Automated, Data-Driven Digital Twin Generation from Multiphysical Simulation Models
A digital twin is a virtual set of information replicating its physical counterpart at the utmost fidelity. Digital and physical twin benefit from bi-directional data exchange that occurs in real time and over the whole process lifecycle. Until now, experts in the design phase have ... Per saperne di più
