  2. Cylindrical harmonics - Wikipedia

    en.wikipedia.org/wiki/Cylindrical_harmonics

    The cylindrical harmonics for (k,n) are now the product of these solutions and the general solution to Laplace's equation is given by a linear combination of these solutions: (,,) = | | (,) (,) where the () are constants with respect to the cylindrical coordinates and the limits of the summation and integration are determined by the boundary ...

  3. Schlichting jet - Wikipedia

    en.wikipedia.org/wiki/Schlichting_jet

    The problem was formulated and solved by Hermann Schlichting in 1933, [1] who also formulated the corresponding planar Bickley jet problem in the same paper. [2] The Landau-Squire jet from a point source is an exact solution of Navier-Stokes equations , which is valid for all Reynolds number, reduces to Schlichting jet solution at high Reynolds ...

    en.wikipedia.org/wiki/Potential_flow_around_a...

    The problem of potential compressible flow over circular cylinder was first studied by O. Janzen in 1913 [4] and by Lord Rayleigh in 1916 [5] with small compressibility effects. Here, the small parameter is the square of the Mach number M 2 = U 2 / c 2 ≪ 1 {\displaystyle \mathrm {M} ^{2}=U^{2}/c^{2}\ll 1} , where c is the speed of sound .

  5. Green's function for the three-variable Laplace equation

    en.wikipedia.org/wiki/Green's_function_for_the...

    The free-space circular cylindrical Green's function (see below) is given in terms of the reciprocal distance between two points. The expression is derived in Jackson's Classical Electrodynamics. [1] Using the Green's function for the three-variable Laplace operator, one can integrate the Poisson equation in

  6. Inverse kinematics - Wikipedia

    en.wikipedia.org/wiki/Inverse_kinematics

    An analytic solution to an inverse kinematics problem is a closed-form expression that takes the end-effector pose as input and gives joint positions as output, = (). Analytical inverse kinematics solvers can be significantly faster than numerical solvers and provide more than one solution, but only a finite number of solutions, for a given end ...

  7. Parabolic cylinder function - Wikipedia

    en.wikipedia.org/wiki/Parabolic_cylinder_function

    Parabolic cylinder () function appears naturally in the Schrödinger equation for the one-dimensional quantum harmonic oscillator (a quantum particle in the oscillator potential), [+] = (), where is the reduced Planck constant, is the mass of the particle, is the coordinate of the particle, is the frequency of the oscillator, is the energy, and () is the particle's wave-function.

  8. Revolute joint - Wikipedia

    en.wikipedia.org/wiki/Revolute_joint

    The contact between the inner and outer cylindrical surfaces is usually assumed to be frictionless. But some use simplified models assume linear viscous damping in the form T = B ω {\displaystyle T=B\,\omega } , where T is the friction torque , ω is the relative angular velocity , and B is the friction constant.

  9. MOOSE (software) - Wikipedia

    en.wikipedia.org/wiki/MOOSE_(software)

    ReActive Transport (RAT) has been developed to solve reactive transport problems in subsurface porous media that involves highly nonlinearly coupled physical processes of fluid flow, solute transport, biogeochemical reactions and media-solution interactions. These problems are common in various subsurface-engineered systems, such as engineered ...
