Parallel block–selective algebraic multigrid in foam‐extend
PAMM, 2019AbstractWe present an extension of a well–known classic algebraic multigrid algorithm, where coarsening is based on selection of equations, for an implicitly coupled pressure–velocity system discretised by the finite volume (FV) method. The resulting coefficient matrix of the linear system is point–ordered, and there are 4 equations for each FV cell ...

Water-blown flexible polyurethane foam extended with biomass materials
Journal of Applied Polymer Science, 1997Soy protein isolate, soy fiber, and cornstarch (0–40% polyether polyol) were incorporated into a flexible polyurethane foam formulation. Stress–strain curves of the control foam and foams containing 10–20% biomass material exhibit a considerable plateau stress region but not for foams extended with 30–40% biomass materials.

SLIDING WEAR SIMULATIONS IN FOAM-EXTEND
2022The presence of wear is a well-known reason for the failure of mechanical components in mechanical systems. Wear was rarely studied in detail using numerical analysis and was usually accounted for in the design stage of components by relying on complex and financially demanding experiments or engineering experience.

Flexible Polyurethane Foam Extended with Corn Starch
1997The use of polyurethane foam is continuing to grow at a rapid pace throughout the world. This growth can be attributed to their light weight, excellent strength/weight ratio, energy absorbing performance (including shock, vibration, and sound), and comfort features of the polyurethane foams (Klempner and Frisch, 1991).

Enhanced Turbomachinery Capabilities for Foam-Extend: Development and Validation
2019Turbomachinery simulations represent one of the most challenging fields in Computational Fluid Dynamics (CFD). In the recent years, the general CFD ca- pabilities of foam-extend have been extended by introducing and maintaining addi- tional features specifically needed for turbomachinery applications, with the aim of offering a high quality CFD tool ...

Journal of Applied Polymer Science, 2001
The use of renewable resources (mainly carbohydrates) in rigid polyurethane foam has been known to offer several advantages, such as increased strength, improved flame resistance, and enhanced biodegradability. Less attention has been directed to inexpensive protein-based materials, such as defatted soy flour.
