Fractional Heat Conduction

The contribution deals with the fractional heat conduction models and their use for determining thermal diffusivity. A brief historical overview of the authors who have dealt with the heat conduction equation is described in the introduction of the paper. The one-dimensional heat conduction models with using integer- and fractional-order derivatives are listed. Analytical and numerical methods of solution of the heat conduction models with using integer- and fractional-order derivatives are described. Individual methods have been implemented in MATLAB and the examples of simulations are listed. The proposal and experimental verification of the methods for determining thermal diffusivity using half-order derivative of temperature by time are listed at the conclusion of the paper.

Good Agreement

It is essential to accurately predict or model the residual stresses in a material resulting from various manufacturing operations. Numerical methods were used in this study to predict the residual stresses after quenching and cold compression of an Al 7085 forged block. Experimental verification was provided by comparing the measured distortions due to a relaxation of the residual stresses with the predictions obtained by using a simulated stress field. The validation was carried out on a simplified structural part. The measured and simulated distortions were found to be in good agreement with each other. The results indicated that part distortion is attributable to the relaxation of bulk residual stresses.

Particulate Matter Formation

This paper contains results of mathematical modeling connected with non-conventional energetic system using the cooling combustion engine (the engine cooling circle is the ejector of absorption cooling). We especially have focused on the influence of a more intensive cooling on the engine ecological parameters. The paper is a continuation of previous publications and focuses on the results of the designed mathematical model of particulate matter formation and its experimental verification under extreme intercooling. Our previous achievements were already presented on scientific conferences and in professional journals.
