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...

In modified atmosphere packaging (MAP) of horticultural produce, prediction of the evolution of gaseous O2 and CO2 concentrations inside packages is important to evaluate package performance and to reduce number of experimental trials needed to select packaging conditions. Mathematical modelling constitutes a useful tool in MAP design. A mathematical model for predicting oxygen (O2), carbon dio...

The advent of nanocrystalline metal oxide semiconductor permits microheater to be incorporated into integrated gas sensors to heat the sensing layer to a low temperature. The low temperature sensing allows the use of a relatively thin silicon membrane instead of zero Silicon membrane resulting into temperature uniformity across the entire active area (2mmx2mm) which in turn reduces the reliabil...

Finite element (FE) modelling of ultrasonic propagation using Comsol Multiphysics, or indeed any other FE software, inevitably involves large computations because two or three dimensional time-stepping models are needed to predict the behaviour of these kinds of travelling mechanical waves. Comsol can be used to create video of waves in these models, which is both attractive and informative. Un...
