Chaotic Convection in a Viscoelastic Fluid Saturated Porous Medium with a Heat Source

Chaotic convection in a viscoelastic fluid saturated porous layer,heated from below,is studied by using oldroyd's type constituting relation and in the presence of an internal heat source. a modified darcy law is used in the momentum equation,and a heat source term has been considered in energy equation. an autonomous system of fourth-order differential equations has been deduced by using a truncated fourier series. effect of internal heat generation on chaotic convection has been investigated. the asymptotic behavior can be stationary,periodic,or chaotic,depending upon the flow parameters. construction of four-scroll,or two-butterfly, and chaotic attractor has been examined. © 2016 b. s. bhadauria.
