Model of conduction
WebIn this work, we present a novel approach for mathematical modeling of electrical conduction in cardiac tissue composed of myocytes, fibroblasts, and the extracellular space. The model is an extension of established cardiac bidomain models, which include a description of intra-myocyte and extracellular conductivities, currents and potentials in ...

WebConduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. Conduction is the … WebThis chapter presents the basics of heat, temperature, and Newton’s law of cooling, which is a model that is accurate when most heat transfer is by conduction and convection, not radiation. To simulate a hot cup of coffee, we wrote Newton’s law as a difference equation, then wrote a version of run_simulation that implements it.
Web2 feb. 2011 · Conduction is a diffusion process by which thermal energy spreads from hotter regions to cooler regions of a solid or stationary fluid. A range of microscopic diffusive mechanisms may be involved in heat conduction (Gebhart (1993)) and the observed overall effect may be the sum of several individual effects, such as molecular diffusion, … Web15 sep. 2024 · Upscaled models are derived from the periodic homogenization technique for conduction-convection-radiation problem in porous media for the case of an opaque solid and transparent fluid. Thermal radiation at the pore-scale level is first described through a differential view factor between elementary surfaces. Such heat transfer mode …
