Single Process Production of 3D Nonwoven Shell Structures: Part 2 — CFD Modeling of Thermal Bonding Process

Numerical (CFD) Analysis of Thermal Spray Coating Process

Contour Crafting Process Plan Optimization Part I: Single-Nozzle Case

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...

Multiscale Modeling of Hvof Thermal Spray Process

The major physicochemical processes involved in an industrial HVOF thermal spray process (Diamond Jet hybrid gun, Sulzer Metco, Westbury, NY) are studied by a comprehensive multiscale model. The model includes continuum type differential equations that describe the dynamics of gas phase and particles of different sizes, and a rule-based stochastic simulator that predicts the evolution of coatin...

Potential pitfalls of process modeling: part B

Purpose – This second part of the paper summarizes typical pitfalls as they can be observed in larger process modeling projects. Design/methodology/approach – The identified pitfalls have been derived from a series of focus groups and semi-structured interviews with business process analysts and managers of process management and modeling projects. Findings – The article continues the discussio...
