The objective of this work is to develop a surrogate model for the Rayleigh-Bénard convection problem, which is a type of natural convection occurring in a horizontal plane layer of fluid heated from ...

The curve of critical Rayleigh number as function of wavenumber is computed and plotted and the minimum value of the Rayleigh number is obtained along with the corresponding value of the wavenumber.

ABSTRACT: An initial value problem concerning the motion of an incompressible, electrically conducting, viscoelastic Oldroyd-B fluid bounded by an infinite rigid non-conducting plate is solved. The ...

Abstract: Rayleigh–Stokes problems have in recent years received much attention due to their importance in physics. In this article, we focus on the variable-order Rayleigh–Stokes problem for a heated ...

Rayleigh-Bénard convection is the buoyancy-driven flow of a fluid heated from below and cooled from above and is a paradigm for nonlinear dynamics with important applications to meteorology, ...

Abstract: There are three problems that arise from attempts to characterize the Rayleigh problem that are of interest to computer scientists: characterizing noise distributions that occur in real time ...

In this paper we present an algorithm for solving the inverse Sturm-Liouville problem with symmetric potential and Dirichlet boundary conditions. The algorithm is based on the Rayleigh-Ritz method for ...

ABSTRACT: The analogy between eigenvalues and singular values has many faces. The current review brings together several examples of this analogy. One example regards the similarity between Symmetric ...
