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 ... En savoir plus

Thermal flow meters represent a vast range of sensors for applications in oil and gas, sustainable energy, food and medical care markets, where precise control of the mass flow is required. As a part of the MEMS production process, testing is performed after product assembly. Due to high ... En savoir plus

The modern microjet engine industry faces an ultimate constraint - a lack of physical platform for innovation, a need to completely develop new, existing technology to eventually test theory. Hence our proposal and development of a framework micro jet engine to be used as a platform for ... En savoir plus

In the nuclear fuel industry, the dry conversion process is employed to transform crystalline UF6 to UO2 powder, in order to produce fuel pellets. The quality of the finished product highly depends on the process input parameters, and it is imperative to understand accurately the full ... En savoir plus

Large arrays, typically consisting of thousands of devices, made from thin film PZT MEMS technology are increasingly being used in several applications including industrial inkjet printers, adaptive optics and so on. Thin film PZT is attractive because of lower operating voltages and ... En savoir plus

Lithium-ion batteries (LIBs) have become a major choice for electric vehicles and renewable energy storage systems owing to their high energy density and high charging efficiency. While LIBs play a crucial role in meeting global energy demand, during long-term operation they undergo ... En savoir plus
