This book is, may be, the most interesting work on the Galerkin method. It starts with the ascertained fact that ”any problem for which governing equations can be written down is a candidate for a Galerkin method”. The work starts with the traditional variant of the Galerkin method, and finishes with generalizations of this method. In its course, the computational variant is treated, as well as the finite element variant, spectral methods, etc. Comparisons are also made between these methods and the finite differences method. It is remarkable that the author inquires and discusses about convergence, stability and accuracy. Relations with the boundary element method are made as well. The method is variously applied. But the most important applications are those in fluid dynamics. So, Burger’s equation is treated, problems linked to the behaviour of viscous and inviscid fluids, heat transfer, and boundary layer problems, all in the steady and unsteady variants. Regarding the finite element variant of the method the use of triangular and rectangular elements is discussed. The work ends with some Fortran subroutines for solving Burger’s equation. This all forms a beautiful pleading for the application of the Galerkin method in different fields of engineering.
