Gas lubricated bearing has been developed for high accuracy in precision machines and equipments. Gas lubricated bearings are mainly two types: aerostatic bearings, which require a feed of pressurized gas for their operation, and aerodynamic bearings, which generate their own internal pressure differentials. The latter generate this pressure by the action of simultaneously shearing and squeezing ...

This model studies a portion of the vascular system of a normal person, in particular the left ventricle and the mitral valve of the heart. The flowing blood applies pressure to the ventricle before, after and specially during the contraction process of the heart, thereby deforming the structure.

The model for study of thermal mechanical behavior of multilayer thin films was developed. The stress-strain analysis was carried out in combination with thermal effects. The 2D thinfilm model has been solved by FEMLAB 3.1i. The middle layer was thermally loaded with Ohmic heating and other layer’s thicknesses were varied in time. All material data like elastic coefficients, thermal ...

High cost and complexity of technological equipment for manufacturing in aeronautical engineering, necessity of fast reequipment for creation of new modifications of flight vehicles make the use of software for modeling prior to design activities very topical. Manufacturing of a polymeric composite spar of the helicopter main rotor blade is an example of technology, where it is necessary to ...

The self-induced ion plating (SIIP) process is a new physical vapor deposition process based on the evaporation of a metallic target (i.e. tin) thanks to a magnetron sputtering system. The aim of this work is to develop a numerical simulation model of the SIIP process in order to predict the target temperature field and from it, the coating profile on the substrate. The simulation of the SIIP ...

The subject of our study belongs to the large area of studies about the analyze and the prediction of indoor air quality. One of the actual weaknesses for the appreciations of air indoor quality is the lack off knowledge about the interactions between the pollutants and the materials (emission off VOC, adsorption). Knowing the behavior of construction materials we can figure out the possibility ...

Infrared photonic detectors operating in the mid infrared region find applications in pollution monitoring, high-speed infrared imaging systems and free space telecommunications. There is a need for new uncooled high performance detector systems and antimonide-based (Sb-based) semiconductor quantum structures could be an alternative of the well-established technologies. The main objective of ...
Gyros AB is developing biomedical laboratories in CD-discs, Gyrolab®. In a lot of applications mixers are needed and for some special applications liquid volumes of a few microlitres are to be handled. The mixing of a few microlitres liquids was studied numerically with FEMLAB and experimentally with colored and uncolored water. Thanks to this combination, the main mixing process was ...
