    Sammanfattning : The genus Rickettsia belongs to the α-proteobacteria and consists of obligate intracellular bacteria, which often are pathogenic for humans. All Rickettsia have small genomes, highly adapted to an intracellular lifestyle. LÄS MER

  4. 3. Droplet Breakup in Automotive Spray Painting

    Författare :Björn O Andersson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomization; spray painting; computational fluid dynamics; breakup; surface tension;

    Sammanfattning : Paint and surface treatment processes in a car paint shop are to a largeextent automated and performed by robots. Having access to tools thatincorporate the flexibility of robotic path planning with fast and efficientsimulation of the processes is important to reduce the time required forintroduction of new car models, reduce the environmental impact and increasethe quality.

  5. 4. Modeling and simulation of rotary bell spray atomizers in automotive paint shops

    Författare :Björn O Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray painting; computational fluid dynamics; atomization; multiphase flow; breakup; coating; surface tension;

    Sammanfattning : The paint and surface treatment processes in automotive paint shops are characterized by multiphase and free surface flows, multiphysics interactions, multiscale phenomena, and large moving geometries. The current version of the software for simulation of spray painting developed at the Fraunhofer-Chalmers Centre relies on measurements of droplet size distributions and velocity profiles below the applicator that can be used as input to the simulations.
