Abstract In embedded systems that necessarily require a steady source of power and (or) attaches to sensor(s), there are opportunities mix small batteries supply such power. The aim this research is optimize the geometry shape piezoelectric cantilevers harvest more Several cantilever geometries with various shapes (rectangular, triangular, circular, trapezoidal cross section) tested in COMSOL m...

The Purpose of the paper. study thermal physics process drilling polymer composite materials based on capabilities engineering package Comsol Multiphysics. Determination values temperatures arising in cutting zone when with a tool materials, namely, carbon fiber. Establishment depth heat propagation inside workpiece from edge formed hole material. In this work, Fourier equations are used. Numer...

A method to linearize partial differential equations (PDEs) of heat diffusion and its initial with boundary conditions in a wide interval temperature is presented. Thus, an analytical solution the conduction problem was achieved virtual experiment performed lead wall ideally established configuration. For other arrangements where not possible, simple standard programs can be used as alternative...
