Effect of radial velocity profiles on axial dispersion in packed beds: asymptotic behaviour
(Brazilian Society of Chemical Engineering, 2021-09)
Axial dispersion of a solute in a flow through packed beds arises from molecular diffusion, velocity variations at the interstitial-pore scale and systematic radial velocity profiles. Currently, there is not a widely ...
Radial sign-changing solutions to biharmonic nonlinear Schrodinger equations
(Springer, 2015-01-31)
In this work we obtain three radial solutions of a biharmonic stationary Schrodinger equation, one being positive, one negative, and one sign changing. The dual decomposition method is used to split the natural second-order ...
Meshless Method for the Numerical Solution of Coupled Burgers Equation
(Universidad EAFITMaestría en Matemáticas AplicadasEscuela de Ciencias. Departamento de Ciencias BásicasMedellín, 2022)
The development and interest in numerical techniques for obtaining approximate solutions to partial differential equations have increased very much in the last decades. Among these are meshless methods. Recently radial ...
Positive solutions for a class of equations with a p-Laplace like operator and weights
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
In this paper we will study the problem of existence of positive solutions to the problem
A control volume scheme using compact integrated radial basis function stencils for solving the Richards equation
(Elsevier B.V., 2020-01-01)
A new control volume approach is developed based on compact integrated radial basis function (CIRBF) stencils for solution of the highly nonlinear Richards equation describing transient water flow in variably saturated ...
A Robin problem for a class of quasilinear operators and a related minimizing problem
(Nonlinear Analysis: Theory, Methods & Applications, 2019)
Solutions of the three-dimensional radial Dirac equation from the Schrödinger equation with one-dimensional Morse potential
(2017-07-12)
New exact analytical bound-state solutions of the radial Dirac equation in 3+1 dimensions for two sets of couplings and radial potential functions are obtained via mapping onto the nonrelativistic bound-state solutions of ...
Positive radial solutions for quasilinear equations = Soluciones radiales positivas para ecuaciones cuasilineales.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Matemática., 2020)
The study of existence, multiplicity and non-existence of positive solutions to semi-linear and quasi-linear elliptic equations is relevant to many applications ranging from thermal iginition of gases [14], quantum field ...
