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
Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach
In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... Per saperne di più
Elastohydrodynamics of Roll-to-Plate Nanoimprinting on Non-Flat Substrates
Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with UV-curable resins. Figure 1 shows a schematic of the roll-to-plate imprint process, which is considered in this study [1]. It uses several rollers, for imprinting and ... Per saperne di più
Electrochemomechanical Simulations of 3D-Resolved Solid-State Lithium-Ion Battery Cells
Solid-state batteries have emerged as a viable alternative to traditional liquid-based lithium-ion batteries, offering improved cost efficiency, safety, and environmental impact. Chlorine-rich lithium argyrodite (Li6PS5Cl) has emerged as a promising solid-state electrolyte, presenting ... Per saperne di più
Exploring a Cost-Effective Approach for Digital Radio Broadcasting Service Coverage Inside Tunnels
In the recent years, Rai Research Centre (CRITS) has been involved in investigating solutions to guarantee a satisfactory coverage of Digital Audio Broadcasting (DAB) service, in the 200 MHz frequency band, for challenging scenarios like tunnels.
