:This book emphasizes the numerical methods of solving boundary problems for nonlinear equations of aerohydrodynamics, especially partial differential and integro-differential equations. Topics discussed include an analysis of transonic gas flows and three-dimensional supersonic flows, the simulation of viscous fluid flows, perturbation development in a boundary layer, and approaches to constructing adaptive grids. The book will appeal to professional aeronautical engineers, applied physicists, applied mathematicians, and geophysicists.
