Synopsis

Numerical Analysis Proceedings of the Colloquium on Numerical Analysis Lausanne, October 11-13, 1976 by J. Descloux, J. Marti

Nowadays aluminium is essentially produced according to the Hall-H~roult process, in other words, by electrolysis of alumina A1 0 desolved in molten cryolite Na A1F at a 2 3 3 6 temperature of about 950 C. In a reduction plant cells are connected in series. For technical and economical reasons, it is advisable to choose large nominal currents (150 kAle For such intensities, the electromagnetic effects in the cells become important. In particular, these effects bring about movements in the liauid metal, as well as interface variations in level, that are detrimental to efficiencv and energy consumption [l,~ * For an optimal design, it is necessary to predetermine the electromagnetic behaviour of each new typ of cells. It is specially necessary to calculate the repartition of the current density in each point of the cell (electric problem), and the magnetic induction produced in the liquid metal by the currents circulating in the cell itself, in the near cells and in the external conductors (magnetic problem). Electric problem formulation Stationary electric phenomena are described by the equations ~ ...rotE=O (1) ...divJ=O (2) t=f1 (3) The first equation can be replaced by t=-g;tdU (4) where U is the electric potential. J. -M. BLANC 131 ~ -+ We can eliminate E and J between the equations above. In an homogeneous material, we obtain a Laplace's equation (5) 4u=0 On surfaces separating material of different resistivities, ...

We love Lovereading4kids because they put books in front of us we wouldn’t otherwise have read. They make us more adventurous readers!

Emily Jacques

It’s so easy to find the right book for your child. Such an easy-to-use, yet in-depth website. 100% reliable.

Pippa, Jack, Liam & Matthew Wils

It is THE website to use for narrowing down your search for any book. Definitely knocks the socks off any other book review website.

Nickey and Tomasz Hawryszczuk

I love lovereading4kids because I’ve read amazing books I would never have picked up, and its opened doors to new genre’s I now love.

Harriet Cunningham

Love “Lovereading4kids” as my son gets to hear about & read new books before his mates which keeps him interested in reading=a very happy Mum

Liz Evans

This company is amazing; not only is it is a great opportunity to get books and review them but everyone is so friendly and supportive!

Jemma Rubens, age 10

We love Lovereading4kids because it promotes reading choices, new authors and a sense of community for children of all ages!

Rachel Bridgeman

It has introduced my children to books we hadn’t come across before. Real children’s reviews gives a great insight into what others think to
