JIMENEZ RAMOS, Antonio et al. Wolfram Mathematica, applied to the heat transfer method exact solution for extrusion processes. Energética [online]. 2017, vol.38, n.1, pp. 73-84. ISSN 1815-5901.

Computer programs for the solution to problems of everyday life, are very common, how quickly results can be obtained, than by traditional methods would be very laborious, and the conclusions to be arrived, for those in solutions , lead repeated calculations, even more. The aim of this work is to demonstrate, and through programming with Wolfram Mathematica 8.0 for the method of the exact solution, quick results are achieved and more accurately than by the method of approximation, the first term or any other, making it possible, depending on the worked geometries, perform different types of comparisons or studies demonstrating their behavior, to various parameters taken into account, on equal terms, as they are, geometric properties, as diameter, length, thickness, volume and physical properties such as thermal conductivity, specific heat and density, appreciating how they influence on results as cooling times, production according to the physical properties and equipment design, consumption rates, temperatures in the center and surface and others, according to the method of extruding plastic pipes, very necessary in production processes requiring precise monitoring and constant

Palabras clave : plastic extrusion; simple geometries; modeling; physical properties; heat transfer; software wolfram mathematica.
