Effects of pressure work over a semi-infinite vertical oscillating cylinder

Sarojini A., Palani G.

International Journal of Applied Mechanics and Engineering

2021

Vol. 26, no. 1

215--225

An arithmetical methodology is used to study natural convection with properties of pressure work over a semi-infinite vertical oscillating cylinder. The governing partial differential equations are set up and the resulting equations are changed into a non-dimensional form using the proper non-dimensional quantities. The set of non-dimensional partial differential equations is solved arithmetically using a well-organized method known as the Crank-Nicolson method. The velocity, as well as temperature profiles for different values of parameters are studied with the assistance of graphs.

Crank-Nicolson semi-implicit approach for numerical solutions of two- dimensional coupled nonlinear Burgers' equations

Srivastava V. K., Tamsir M.

571-581

The two-dimensional Burgers' equation is a mathematical model which is used to describe various kinds of phenomena such as turbulence and viscous fluid. In this paper, Crank-Nicolson semi-implicit scheme is used to handle such problem. The proposed scheme forms a system of linear algebraic difference equations to be solved at each time-step. The linear system is solved by direct method. Numerical results are compared with those of exact solutions and other available results. The present method performs well. To our best knowledge no one has solved Burgers' equations using this scheme. The proposed scheme can be extended for solving non-linear problems arising in various branches of engineering and science.
