‎in this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎a low dimensional lorenz‎- ‎like model is obtained by using galerkin-truncation approximation‎. ‎we found that there is proportional relation between scaled couple ...

The geometry under consideration for this flow problem, namely paraboloid surface is similar to aircraft and car bonnet, bullet shape, front shape of submarine, rockets these types are useful in manufacturing formula F1 cars airplanes. fluid over has several applications space science, industries, mechanical works architecture. aim study explore the Cattaneo-Christov heat mass flux model steady...

In this study, the effect of the tube material on the thermal stress generated in a vertical shell and tube heat exchanger is investigated. Shell and tube heat exchangers are the most common heat exchangers used in industries. One of the most common failures in these exchangers in the industry is the tube failure at the junction of the tube to tubesheet. When the shell side and the tube side fl...

Abstract This article addresses the impact of magnetic field induction on buoyancy-induced oscillatory flow couple stress fluid with varying heating. Modelled equations for incompressible are coupled and nonlinear due to inclusion viscous heating thermal effect density. Approximate solutions constructed coded a symbolic package ease computational complexity. Graphical representations presented ...
