Abstract: The electric field and temperature are the two important factors that influence the fiber diameters and properties in the melt electrospinning process. It is commonly known that the polymer jet behavior is governed by the electric field within spinning area. In the present ... En savoir plus
Laser material processing at micro-meter domain can be used for a plethora of applications such as micro drilling, micro welding, micro cutting, micro-texturing as well as micro polishing. These processes are governed by the time varying, complex melt hydrodynamics courtesy of melting ... En savoir plus
This study explores the significance of the recoil pressure, Marangoni convection and surface tension effects in selective laser melting of Ti-6Al-4V. A pragmatic two dimensional model with appropriate powder distribution over a substrate of finite thickness has been developed in COMSOL ... En savoir plus
Laser-Heated Pedestal Growth (LHPG) is a crystal growth technique that employs a focused laser beam to melt a source material, creating a molten zone that is precisely controlled to produce high-quality single crystals. This method is particularly advantageous for growing crystals with ... En savoir plus
During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non ... En savoir plus
Thermocouples are widely used in industry for process temperature measurement. Calibration drift is a well-known problem which adversely affects process control, particularly in harsh environments (e.g. high temperature). To overcome this, a mechanism for self-calibration of ... En savoir plus
