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

Geothermal energy systems require precise sizing to ensure efficiency and sustainability, particularly for probe fields and groundwater doublets. We present two specialized applications developed using COMSOL Multiphysics’ Application Builder, leveraging the Heat Transfer and Groundwater ... 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

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

Fire resistance tests of building elements are essential for evaluating their ability to withstand fire exposure and prevent fire spread. Fire resistance tests are expensive and usually take months to organize. If the same structure is retested at the same lab, the systems are so complex ... En savoir plus
