If you're coding, I suggest you read Ferziger and Peric book Computational Methods for FLuid Dynamics and their paper Further discussion of numerical errors in CFD. Computational Fluid Dynamics (CFD) is the standard numerical tool used by Fluid Dynamists to estimate solutions to many problems in academia, government, and industry.

CFD is known to have errors and uncertainties and there is no universally adopted method to estimate such Size: 2MB. Nonlinear Dynamics represents a wide interdisciplinary area of research dealing with a variety of “unusual” physical phenomena by means of nonlinear differential equations, discrete mappings, and related mathematical algorithms.

However, with no real substitute for the linear superposition principle, the methods of Nonlinear Dynamics Cited by: The journal serves as a forum for the exchange of new ideas and applications in computational, rigid, and flexible multi-body system dynamics and all aspects (analytical, numerical, and experimental) of dynamics associated with nonlinear systems.

Applied Nonlinear Dynamics provides a coherent and unified treatment of analytical, computational, and experimental methods and concepts of nonlinear dynamics. Analytical approaches based on perturbation methods and dynamical systems theory are presented and illustrated through applications to a wide range of nonlinear by: Computational Structural Mechanics & Fluid Dynamics Advances and Trends.
