Since the appearance of computers, numerical methods for discontinuous
solutions of quasi-linear hyperbolic systems of partial differential
equations have been among the most important research subjects in
numerical analysis. The authors have developed a new difference method
(named the singularity-separating method) for quasi-linear hyperbolic
systems of partial differential equations. Its most important feature is
that it possesses a high accuracy even for problems with singularities
such as schocks, contact discontinuities, rarefaction waves and
detonations. Besides the thorough description of the method itself, its
mathematical foundation (stability-convergence theory of difference
schemes for initial-boundary-value hyperbolic problems) and its
application to supersonic flow around bodies are discussed. Further, the
method of lines and its application to blunt body problems and conical
flow problems are described in detail. This book should soon be an
important working basis for both graduate students and researchers in
the field of partial differential equations as well as in mathematical
physics.
