| dc.description.abstract | El desarrollo del 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 varias aplicaciones de ingeniería, tales 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 con 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 de ofrecer un método alternativo para calcular la
temperatura utilizando el método numérico explícito. El cálculo de la temperatura
a lo largo de la barra se compara mediante el método analítico y el numérico, calculando el porcentaje de error,
y se trazan diferentes perfiles de temperatura para verificar el ajuste de los dos enfoques. Los métodos
desarrollados a lo largo de la investigación pueden extenderse a otros tipos de fenómenos físicos que
son útiles en investigaciones relacionadas y en la enseñanza de materias de 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 |
