Prints in 3-5 business days
This is an extended version of my PhD thesis which extends the theory of finite element exterior calculus (FEEC) to parabolic evolution equations. In the extended version, I explore some more precise... More > visualizations of the defined quantities, as well as explain how the modern theory of functional analysis applies. In the main part, I extend the theory of approximating evolution equations in Euclidean space (using FEEC) to hypersurfaces. After these main results, I describe some possible extensions to nonlinear equations. A few appendices detail one of the original motivations for getting into this theory in the first place: canonical geometries given as steady state solutions and extremals of certain functionals.< Less

Version 2.4 (Feb. 2017): This is a unique and highly technical book on Computational Fluid Dynamics (CFD). The first half talks about mathematical foundations and governing equations ranging from... More > simple model equations (advection/diffusion, Euler-Tricomi, Cauchy-Riemann, Burgers, etc.) used for algorithm development to the incompressible/compressible Euler and Navier-Stokes equations in various forms with complete Jacobians and eigen-structures in 1, 2, and 3 dimensions. The other half talks about general methods for deriving exact solutions (separation of variables, transformation, superposition, etc.) and numerous exact solutions that can be readily used for accuracy verification of a CFD code (Ringleb's flow, Fraenkel's flow, boundary layer, viscous shock structure, etc.). This book can be a very useful resource for students studying basics of CFD as well as researchers/practitioners in CFD. - PDF version is available at [Note: PDF does not contain some contents of the Printed version.]< Less

Transformation Of Coordinates By narayana dash
eBook (PDF): $0.00
Transformation of orthogonal curvilinear coordinates from one system into another is done through partial differentiation. The transformation matrix is also a simple case of partial... More > differentiation. Another aspect of coordinate transformation is Compression of coordinates ( Change of scale in graph) resulting in deformation of graphs. A grand example of this is given by deriving the equations of conic sections from the equation of circle. Finally a grand example of transformation of coordinates would be Lagrange’s equations. The Newton’s Laws of motion have been transformed from Cartesian coordinates into generalized coordinates, . The beauty of Lagrange’s equations lies in the fact that they are invariant in form in any coordinate system. The wonder about it is, that the for divergent problems of quantum mechanics and electromagnetic theory and optics are easily derived from the same Lagrange’s equations using ; the total energy functions in each area.< Less
