A study on Spray Drying in Food Industry
Spray drying is a common drying technique in food industries to convert liquid to powder form. A good understanding on the dynamic behavior of the process is important to ensure proper control. The aim of this study is to develop empirical models for spray drying of whole milk powder and ... Per saperne di più
Simulation of a Plastic Bottles Solar Collector
In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is ... Per saperne di più
Numerical Modeling of Heat and Mass Transfer in Porous Materials During Drying and Shrinkage
Drying is an essential step in many manufacturing processes, for it will have an important impact on the product quality. This is why many numerical models have been realized over decades, in order to predict the hygrothermal behavior of porous media during the drying process. In this ... Per saperne di più
Modeling of HTPEM Fuel Cell Start-Up Process by Using COMSOL Multiphysics
HTPEM fuel cells are considered to be the next generation fuel cells. The electrochemical kinetics for electrode reactions are enhanced by using PBI membrane at an operation temperature between 160-180 °C comparing to LTPEM fuel cells. But starting HTPEM fuel cells from room temperature ... Per saperne di più
Heat Pipe Assisted Thermal Management of an HT PEMFC Stack
Heat management is crucial for the satisfactory operation of HT-PEM (High temperature polymer-electrolyte-membrane) fuel cells. Current work investigates the use of heat pipes in a HT PEMFC stack consisting of 24 cells, each with an active area of 300 cm^2. Heat pipes are known to be ... Per saperne di più
A Study of Thermo-Fluid Behavior in Tubular Metal Hydride Beds in the Hydriding Process
Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption ... Per saperne di più
3D Stationary and Temporal Electro-Thermal Simulations of Metal Oxide Gas Sensor Based on a High Temperature and Low Power Consumption Micro-Heater Structure
The aim of this work was to simulate the electro-thermal behavior of a micro-hotplate used as a gas sensor, in order to compare the obtained results with a real structure. The structure has been designed in 3D and a stationary and a temporal study has been realized. Per saperne di più
Building a Complex Geological Model Using Parametric Surfaces
Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not ... Per saperne di più
Highly Concentrated Solar Radiation Measurement by Means of an Inverse Method
This work focuses on the numerical analysis conducted on the prototype sensor for the measurement of highly concentrated radiative heat fluxes, based on an inverse heat transfer method, realized at the ENEA Portici Research Center in collaboration with the DETEC department of the ...
