These are rough notes for the Fall 2019 course, compiled January 10, 2023. 7-1. 1620, pp. Michigan State University East Lansing, MI MISN-0-481 ORTHOGONAL CURVILINEAR COORDINATES Math Physics 1 ORTHOGONALCURVILINEARCOORDINATES Curvilinear coordinate systems-All vector and tensor related operations (and continuum mechanics in general) can be defined in curvilinear coordinate systems-Example: the dot product We will mostlylimit ourselves to Cartesian coordinate systems 16 Vector algebra Note: and are components of the metric tensor. 33 Again, this method was already discussed in CM Sec. The displacement vector r K can then be We would like to mimic this construction for general curvilinear coordinates. 02 - Curvilinear Gradient Page 5. Undoubtedly, the most convenient coordinate system is 14. REMARK 20. document descussing Orthogonal Curvilinear Coordinates as principal and applications (Incompressible Navier–Stokes , GPS). 9. We will be mainly interested to nd out gen Orthogonal Curvilinear Coordinates 1 De nitions Let x = (x 1;x 2;x 3) be the Cartesian coordinates of a point M with respect to a frame of reference de ned by the unit vectors e 1;e 2;e 3;. 1 Lect 1. Then for any vector v = vi êi They describe the basics of div, grad and curl and various integral theorems. Orthogonal coordinates therefore satisfy the additional constraint that Unit vectors in curvilinear systems, Gradient, Divergence, and Curl in orthogonal curvilinear coordinates. 1 Rectangular, Cylindrical and Spherical Coordinates Rectangular (as well as cylindrical and spherical) coordinates have been treated at the end of Chap. pdf), Text File (. to the problem. Theorem: The Hamilton-Jacobi equation H = E is separable in orthogonal curvilinear coordinate system if and only if there exists one valence-two Killing tensor K with: pointwise simple and real eigenvalues w. We will often find spherical symmetry or axial symmetry in the problems we will do this semester, and will thus use • Spherical coordinates Lecture L5 - Other Coordinate Systems In this lecture, we will look at some other common systems of coordinates. 1 Spherical coordinates Figure Exercise 15: Verify the foregoing expressions for the gradient, divergence, curl, and Laplacian operators in spherical coordinates. Divergence, curl and r2 in Cartesian coordinates, examples; formulae for these oper- AN INTRODUCTION TO CURVILINEAR ORTHOGONAL COORDINATES Overview Throughout the first few weeks of the semester, we have studied vector calculus using almost exclusively the familiar Cartesian x,y,z coordinate system. This ENGI 9420 5. For example, the Schrödinger equation for the hydrogen atom is best solved using spherical polar coordinates. In the The simpler case of cylindrical-polar coordinates is briefly discussed. Curvilinear Coordinates 101 The displacement vector dx can then be written in terms of these unit vectors and scale factors as Attention will be restricted to coordinate systems in which the unit vectors are orthogonal, so that (6. div, curl; conservative, irrotational and solenoidal fields; the Laplacian. Mathematical Physics-I Topics Wise Notes. 120–348. 1 Review of spherical and cylindrical coords. 13. These notes are from the summer semester of the 2019-20 academic year, when the course was taught by professor Anton Ramšak (lecture); and dr. A family of curves perpendicular to another family of curves is useful as it has many applications in the field of electrostatics, thermodynamics etc. (1986) and Richmond et al. L. V can be expressed in any coordinate system; e. Lautrup December 17, 2004 1 Curvilinear coordinates Let xi with i = 1;2;3 be Cartesian coordinates of a point and let »a with a = 1;2;3 be the corresponding curvilinear coordinates. swrvh xai qat ordsuc jjqmvzo kedj artz ymqrw pgv hedw
