Unsteady Convection Diffusion Equation with Random Input Data



Unsteady aerodynamic forces estimation on a square cylinder by TR-PIV
Kurtuluş, Dilek Funda; Davıd, L. (Springer Science and Business Media LLC, 2007-02-01)
The unsteady aerodynamic forces acting on a square cross-sectional cylinder are investigated by means of time-resolved particle image velocimetry (TR-PIV) at Reynolds number 4,900. The objective of the investigation is to prove the feasibility of non-intrusive force measurements around two-dimensional bodies. The PIV measurements performed at a rate of 1 kHz enable a time resolved (TR) description of the vortex shedding phenomenon occurring at 10 Hz and to follow the time evolution of vortex dominated wake....

Unsteady optimal control problems arising from chemical processes
Yücel, Hamdullah; Benner, Peter (null; 2014-06-20)
This talk will focus on the numerical solution of unsteady optimal control problems governed by a system of convection diffusion partial differential equations (PDEs) with nonlinear reaction terms arising from chemical processes. Such problems are strongly coupled as inaccuracies in one unknown directly affect all other unknowns. Prediction of these unknowns is very important for the safe and economical operation of biochemical and chemical engineering processes. Further, the solutions of these PDEs can exh...
Unsteady MHD mixed convection flow in a lid-driven cavity with a heated wavy wall
OGLAKKAYA, F. S.; Bozkaya, Canan (Elsevier BV, 2018-11-01)
The unsteady mixed convection flow under the effect of an externally applied uniform magnetic field is investigated numerically in a lid-driven cavity with a sinusoidal wavy wall. The governing equations given in terms of stream function, vorticity and temperature are discretized by using the dual reciprocity boundary element method (DRBEM) in space and a two-level time integration scheme is employed in time discretization. The simulations focus on the effects of several physical parameters, namely Hartmann...
