High cost and complexity of technological equipment for manufacturing in aeronautical engineering, necessity of fast reequipment for creation of new modifications of flight vehicles make the use of software for modeling prior to design activities very topical. Manufacturing of a polymeric composite spar of the helicopter main rotor blade is an example of technology, where it is necessary to ...

Degradation of components in low-moisture and high-temperature food is difficult to model because of the temperature gradient and long heating time. A method was developed to estimate the thermal properties of grape pomace and the rate constant and activation energy of anthocyanin degredation.

In this paper, we investigate the feedback thermo-mechanical interaction in a pre-pressed rubber block used for resilient elements of composed tram wheels. The structural motion and heat conduction equations are solved interactively as a time-dependent problem. The equality of heat energy density and dissipation energy density realizes the coupling between the equations. The dissipation ...

A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics 3.4 code has been adopted to solve the combined thermal and electromagnetic problem in order to compare the two ...

This study aims to numerically investigate on a passive solar system for indoor heating called as \"Trombe wall\". The transient buoyancy driven flow characterizing that system and the thermal distribution are solved by numerically integrating the governing equations in COMSOL Multiphysics environment. Simulations are carried-out for a time range corresponding to 12 days. The results are ...

The ampacity of a cable depends on the cross section of its conductor. When selecting a cable design for a specific application it is of interest to choose the lowest possible conductor cross section in order to reduce material costs. Therefore an exact calculation of the ampacity is necessary (it is usually limited by the thermal resistance of the insulating cable materials). Commonly the ...

Self-reheating tins are composed of two parts; one of them contains a ready-to-eat preserved product, the other one, the components of an exothermic process which, once started, brings the edible product to the temperature at which it is usually eaten. Some existing data on the temperatures in the heating and heated parts during the process have been used to validate the results obtained by ...

In this paper, an experimental and theoretical study of natural convectional heat transfer from directly grown-on-package carbon nanostructure-based pin fin heatsinks is studied. The simulations are done by using the Heat Transfer Module in COMSOL Multiphysics. To verify the model, we chose a reference commercial Al-based heatsink manufactured by Thermaflo Inc.In all simulations, a rectangular ...

High level radioactive waste (HLW) generated by nuclear fuel cycle is immobilized using glass melters. In Glass melters such as Joule Heated Ceramic Melter (JHCM) electrodes immersed in the glass generates heat by the joule heating due to electric current passing between electrodes through glass. For melter performance it is required to evlaute temperature distribution in the melter. Thermal ...
