Numerical Studies of Spiral- and Scroll-wave Dynamics in Cardiac Tissue: (1) Spiral- and Scroll-Wave Turbulence; (2) Spiral- and Scroll-Wave dynamics in Anatomically and Physiologically realistic Mathematical Models for Canine and Human Ventricular Tissue
A summary of the main results of our studies is given below. In most of our work, we use three mathematical models for cardiac myocytes, namely, the Panfilov model, the Aliev-Panfilov model, and the Hund-Rudy-Dynamic ... -
Numerical studies of three dimensional turbulence with polymer additives and two dimentional tubulence thin films
Our study contrasts clearly dissipation-reduction phenomena in homogeneous, isotropic turbulence and drag reduction in wall-bounded flows. In both these cases, the polymers increase the overall viscosity of the solution ... -

In the present thesis, some problems in unsteady mixed convective boundary-layer flows with double diffusion have been numerically investigated. It consists of five chapters-the first of which is a general introduction to ... -
Numerical Studies On Ductile Fracture Of Pressure Sensitive Plastic Solids
(2010-07-08)Experimental studies have shown that the yield strength of many important engineering materials such as polymers, ceramics and metallic glasses is dependent on hydrostatic stress. In addition, these materials may also ... -
Numerical Studies on Plastic Deformation, Notch Sensitivity and Fracture Behavior of Bulk Metallic Glasses and Composites
Bulk metallic glasses (BMGs) exhibit attractive properties such as high strength and resilience. However, they display negligible tensile ductility due to catastrophic crack propagation inside a dominant shear band (SB). ... -

A Numerical Study of Changes to Flow Organization and their Prognostic Measures
(2018-05-23)Flow induced self-oscillations cause acoustic pressure oscillations of large amplitude in pipe flows. If Reynolds number is treated as a parameter, these floinduced oscillations occur only at discrete and critical values ... -
Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(2013-02-13)In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ... -
A Numerical Study of Droplet Dynamics in Viscoelastic Flows
(2017-10-05)The polymers are integral part of vast number of products used in day to day life due to their anomalous viscoelastic behaviour. The remarkable flow behaviour exhibited by the polymeric fluids including rod climbing, ... -
