The objective of this work is to analyze measuring techniques used in observation boreholes to investigate natural groundwater flow (magnitude and direction). The In-Well-Point-Velocity-Probe (IWPVP) is a technique based on mini tracer tests performed inside observation boreholes to ... En savoir plus
Temperature of sesame paste flowing through a screw-expeller was studied. Screw-expeller used consisted of a rotating tapered screw and a constant-inner-diameter stationary barrel. Since screw diameter was much larger than the sesame paste thickness, an unwrapped model was employed with ... En savoir plus
Microreactors have been used for renewable fuel production due to benefits such as, enhanced mass transfer, improved heat transfer and larger surface-area-to-volume ratios. The steam reforming of methanol over a CuO/ZnO/Al2O3 based catalyst (BASF F3-01) is investigated using 2-D packed ... En savoir plus
Peristaltic pumps are used during pharmaceutical manufacturing processes, for filling, filtration and mixing operations. Goal of this work was to develop a computational model of a peristaltic pump used for filling operations, to predict shear stresses and mass flow rates. For this ... En savoir plus
The calibration of groundwater models is usually limited by the scarcity of direct hydraulic data. The estimation of heterogeneous distribution of hydraulic properties can be improved through a joint or coupled inversion in which the calibration dataset is complemented with geophysical ...

Manufacturing of metal component in industry involves many kind of processes where materials experience high temperature and changes of state. Then, oxidation may become a significant topic regarding industrial requirement and specification. This issue is well-known in welding ... En savoir plus
Because of their zero friction and wear aerostatic bearings are widely employed in applications where very high precision of positioning is required, e.g, slideways and rotary tables for machine tools, synchrotrons and coordinate measuring machines, roundness tester, and other forms of ...

The Leidenfrost effect occurs when a droplet approaches a surface with a temperature much hotter than the boiling point of the liquid. Here, the underside of the droplet is instantly vapourised, allowing it to sit on a cushion of its own vapour, which grants the droplet virtually ... En savoir plus
Laser technologies such as welding, cutting and metal deposition are widely used in the industry. High quality requirements regarding process products cause that there is often a need to monitor the process. For this purpose, optical sensors integrated with a laser head are often used. ...

This work investigates the design of porous ceramic reactors for continuous bioethanol production through simulations using COMSOL Multiphysics®. Porous ceramic structures will be seeded with the yeast Saccharomyces cerevisiae and exposed to a continuous flow of glucose solution, from ... En savoir plus
