A Mechanism of Eddy Generation in A Single Lid-Driven T-Shaped Cavity
Journal Title: Cumhuriyet Science journal - Year 2019, Vol 40, Issue 3
Abstract
The two-dimensional (2D) steady, incompressible, Stokes flow is considered in a T-shaped cavity which has the upper-lid moving in horizontal directions. A Galerkin finite element method is used to investigate a new eddy generation and flow bifurcation. The flow in a cavity is controlled by two parameters and which are associated with the heights of the T-shaped domain. By varying and , the second eddy formation mechanism and the control space diagram are obtained.

The Investigation of Ni (II) Removal by Biocomposite Synthesized with the Immobilization of Candida Utilis on Chitosan
In this study, Ni(II) adsorption was examined with the biocomposite prepared with the immobilization of Candida utilis on chitosan polymer. The FTIR and SEM analyses of chitosan-Candida utilis biocomposite were carried o...
Effect of Ambient and Cryogenic Milling on the Microstructure and Properties of Tungsten Matrix Composites Fabricated by Activated Sintering
Tungsten matrix composites reinforced with TiB2 and Y2O3 particles were fabricated by milling under ambient/cryogenic conditions and Ni activated sintering. Powder blends constituting the W - 1 wt. % Ni - 2 wt. % TiB2 -...
A Strongly Ill-Posed Problem for the Equation
In this work, we consider an inverse problem for an elliptic equation which is strongly ill-posed in Hadamard sense. We prove the uniqueness of the solution of the problem by using Carleman estimates.
