2. 1. Droplet Breakup in Automotive Spray Painting

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

   Abstract : 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.

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

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

   Abstract : 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.

5. 3. On the fluid mechanics of electrochemical coating and spray painting

   Author : Pedro Olivas; KTH; []
   Keywords : mass transfer; electrochemical coating; ion transport; forced convection; diffusion; magnetoelectrolysis; electrolyte; limiting current; numerical simulation;

   Abstract : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. READ MORE

6. 4. Airborne Isocyanates, Aminoisocyanates and Amines

   Author : Daniel Karlsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental health; Miljökemi; Environmental chemistry; amines; aminoisocyanates; isocyanates; polyurethane; exposure; occupational; thermal degradation; chemiluminescence; mass spectrometry; Liquid chromatography; gas chromatography; Miljömedicin; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Abstract : Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. READ MORE
