| dc.description.abstract | El desarrollo de un marco matemático para modelar los fenómenos de conducción de calor en presencia de efectos radiactivos es bien conocido. La importancia del estudio de la conducción de calor en relación con los efectos radiactivos es relevante en diversas aplicaciones de ingeniería, como la combustión, la ciencia de los materiales, la mecánica de fluidos y otras áreas. Esta investigación se basa en el modelo matemático de la ecuación del calor para estudiar el fenómeno físico de la transferencia de calor a lo largo de una barra metálica con lados ligeramente aislados, bajo el efecto de la radiación libre. Para calcular la función de temperatura que permite modelar el proceso de transferencia de calor a lo largo de la barra, se construye paso a paso la solución de la serie de Fourier. Además, se proporciona un método alternativo para calcular la temperatura mediante el método numérico explícito. El cálculo de la temperatura a lo largo de la barra se compara mediante métodos analíticos y numéricos, calculando el error porcentual, y se grafican diferentes perfiles de temperatura para verificar la compatibilidad de ambos enfoques. Los métodos desarrollados a lo largo de la investigación pueden extenderse a otros tipos de fenómenos físicos que son útiles en la investigación y la docencia relacionadas con la ingeniería, como la mecánica de fluidos y la transferencia de calor. | en_US |

| dc.description.abstractenglish | The development of mathematical setting for modeling heat conduction phenomena in the presence of radioactive effects is well known. The importance in the study of heat conduction in relation to radioactive effects is relevant in several engineering applications such as combustion, materials science, fluid mechanics and other areas. This research is based on the mathematical model of the heat equation to study the physical phenomenon of heat transfer along a metal bar with slightly insulated sides with the effect of free radiation. To calculate the temperature function that allows modeling the heat transfer process along the bar, the Fourier series solution is constructed step by step, in addition an alternative method of calculating the temperature by using the explicit numerical method is given. The calculation of the temperature along the bar is compared by analytical and numerical method by computing the percentage error and different temperature profiles are plotted to verify the fit of the two approaches. The methods developed throughout the research can be extended to other types of physical phenomena that are useful in related research and in education in engineering subjects such as fluid mechanics and heat transfer. | en_US |
