Marangoni convection of non‐Newtonian power law fluids in a shallow rectangular cavity

M. Naïmi, M. Hasnaoui, J.K. Platten

Analytical and numerical studies are conducted for two‐dimensional steady‐state Marangoni convection of a non‐Newtonian power law fluid confined in a rectangular horizontal…

Finite element and experimental solutions for the upsetting of pastes

V.A. Norris, M.A. Crisfield, D.C. Kothari, C.J. Lawrence, B.J. Briscoe

Describes an elastic visco‐plastic finite element formulation that is applied to the modelling of pastes. Comparisons are made with experimental results obtained for a particular…

A combined finite/discrete element simulation of shot peening processes – Part II: 3D interaction laws

K. Han, D. Peric´, D.R.J. Owen, J. Yu

Following earlier work on the combined finite/discrete element simulation of shot peening process in 2D case, 3D representation of the problem is established with respect to DE…

Calculating rotational motion in discrete element modelling of arbitrary shaped model objects

M. Kremmer, J.F. Favier

Application of the discrete element method (DEM) to real scale engineering problems involving three‐dimensional modelling of large, non‐spherical particles must consider the…

Structural topology design with multiple thermal criteria

Qing Li, Grant P. Steven, Osvaldo M. Querin, Y.M. Xie

This paper shows how the evolutionary structural optimization (ESO) algorithm can be used to achieve a multiple criterion design for a structure in a thermal environment. The…

Predicting temperature profiles in producing oil wells using artificial neural networks

Fred F. Farshad, James D. Garber, Juliet N. Lorde

A novel approach using artificial neural networks (ANNs) for predicting temperature profiles evaluated 27 wells in the Gulf of Mexico. Two artificial neural network models were…
