Chaos in the thermal convection of a Newtonian fluid with a temperature dependent viscosity
Akyildiz, FT; Bellout, H (Elsevier Science Inc, 2005)The onset of chaotic motion in Newtonian fluid with a temperature dependent viscosity is explored in the context of the Rayleigh-Benard thermal convection setup. Galerkin truncation is used to derive a low-order dynamical ... -
Dispersion of a solute in a Poiseuille flow of a viscoelastic fluid
Akyildiz, FT (Pergamon-Elsevier Science Ltd, 2002)Gill and Sankarasubramanian's analysis of the dispersion of Newtonian fluids in laminar flow between two parallel walls is extended to the flow of non-Newtonian viscoclastic fluids (known as Phan-Thein-Tanner (PTT)), Using ... -
The extended Graetz problem for dipolar fluids
Akyildiz, FT; Bellout, H (Pergamon-Elsevier Science Ltd, 2004)Thermally developing laminar flow of a dipolar fluid in a duct (pipe or channel) including axial conduction (Graetz problem extended) is investigated. The solutions are based on a self-adjoint formalism resulting from a ... -
Longitudinal and torsional oscillations of a rod in a viscoelastic fluid
Akyildiz, FT (Springer Verlag, 1998)The flow of a viscoelastic fluid due to the torsional and longitudinal oscillations of an infinite circular rod is examined. The idealized equation of state to characterise this Liquid is of the implicit Oldroyd-B model, ... -
A method of the determination of a geodesic curve on timelike ruled surface with spacelike rulings
Kasap, E; Akyildiz, FT (Wiley-V C H Verlag Gmbh, 2004)… -
A note on the flow of a non-Newtonian fluid film
Akyildiz, FT (Pergamon-Elsevier Science Ltd, 1998)Film flow of liquids simulated by the third-grade model down a vertical longitudinally oscillating wall is investigated. The non-linear partial differential equation resulting from the momentum equation is solved by the ... -
A note on the flow of a third-grade fluid between heated parallel plates
Akyildiz, FT (Pergamon-Elsevier Science Ltd, 2001)Flow of an incompressible third-grade fluid between heated parallel plates is investigated analytically. An exact solution of the energy equation is given for a constant heat flux at the walls. Results are discussed and ... -
A numerical study for computation of geodesic curves
Kasap, E; Yapici, M; Akyildiz, FT (Elsevier Science Inc, 2005)Consideration is given to the numerical computation of geodesic on surfaces. The method of finite-difference is used for governing non-linear system of differential equations. Then the resulting non-linear algebraic equations ... -
On the dispersion of a solute in Poiseuille flow of a third-grade fluid in a channel
Akyildiz, FT (Pergamon-Elsevier Science Ltd, 2003)Gill and Sankarasubramanian's analysis of the dispersion of Newtonian fluids in laminar flow between two parallel walls are extended to the flow of non-Newtonian viscoelastic fluid (known as third-grade fluid) using a ... -
On the use of Kantorovich method in viscoelastic flow
Akyildiz, FT; Bellout, H; Yapici, M (Wiley-V C H Verlag Gmbh, 2004)… -
Unsteady thermal convection of a non-Newtonian fluid
Demir, H; Akyildiz, FT (Pergamon-Elsevier Science Ltd, 2000)Two-dimensional unsteady natural convection of a non-linear fluid represented by Criminale-Erickson-Filbey (CEF) fluid model in a square cavity is studied. The governing vorticity and energy transport equations are solved ... -
Viscoelastic lubrication with Phan-Thein-Tanner fluid (PTT)
Akyildiz, FT; Bellout, H (Asme, 2004)We analyze the lubrication flow of a viscoelastic fluid to account for the time dependent nature of the lubricant. The material obeys the constitutive equation for Phan-Thein-Tanner fluid (PTT). An explicit expression of ...
