Although both transient entrainment and resetting with single extrastimuli have been demonstrated during sustained ventricular tachycardia related to previous myocardial infarction, the relation between these phenomena has not been defined. Because transient entrainment is only demonstrated when the mechanism of a tachycardia is reentry with an excitable gap, the resetting response to timed pre...

The paper presents a hybrid-Trefftz element approach for the numerical solution of transient linear heat conduction problems. In the proposed method, the transient heat conduction equation is first discretized with respect to time and then the resulting set of elliptic equations is solved by the corresponding time independent hybrid Trefftz element approach. At the end of the paper, the propose...

When two rough bodies slide against each other, asperities on the opposing surfaces interact with each other, defining a transient contact and heat conduction problem. We represent each body by a Greenwood and Williamson asperity model with a Gaussian height distribution of identical spherical asperities. The heat transfer during a typical asperity interaction is analyzed, and the results are c...

The numerical methods of the structural design optimization with transient response constraints have been studied in the paper. The new methods of the response analysis and sensitivity analysis for the transient dynamics and the heat conduction constraints with the precise time integration have been proposed. Particularly, an efficient method of sensitivity analysis for nonlinear transient heat...

1 B. Terry Beck, Kansas State University, Mechanical and Nuclear Engineering Department, 302 Rathbone Hall, Manhattan, KS 66506 [email protected] Abstract  The main objective of this paper is to present two different experiments that have been developed to successfully demonstrate transient heat conduction phenomena. The first experiment illustrates the approximate measurement of transient local h...

This paper deals with transient non-linear heat conduction through the insulation wall of the tank for transportation of liquid aluminum. Tanks designed for this purpose must satisfy certain requirements regarding temperature of loading and unloading, during transport. Basic theoretical equations are presented, which describe the problem of heat conduction finite element analysis, starting from...

Radiative heat transfer in participating medium has been carried out using the finite volume method. The radiative transfer equations are formulated for absorbing and anisotropically scattering and emitting medium. The solution strategy is discussed and the conditions for computational stability are conferred. The equations have been solved for transient radiative medium and transient radiation...
