Para cada geometría se exploraron dos condiciones de flujo diferentes con el objetivo de recrear un conjunto amplio de escenarios de separación. Se hizo un estudio parametrico, utilizando cinco valores del número de Prandtl, entre 0.1 < Pr < 500, y cuatro valores del número de Reynolds, entre 10 < Re < 10000. El número de Nusselt local y promedio, en conjunto con perfiles de velocidad, coeficientes de presión y coeficientes de fricción fueron analizados. De los resultados se observó que los valores del número de Nusselt promediados en las caras tienen un valor máximo pra Pr = 50 entre 10 < Re < 1000. Para Re = 10000, la difusión térmica adquiere mayor relevancia y los valores máximos se desplazan hacia Pr = 5, en la mayoría de los casos, y Pr = 0.72 y Pr = 0.1 en casos puntuales. Con relación al comportamiento local, se observa que la aparición de los valores máximos o mínimos del número de Nusselt, se da en la vecindad de los puntos de separación del flujo, donde la aparición de vórtices influye en el posicionamiento de estos. Del estudio se infiere que, contrario a lo establecido por varios autores y en diferentes libros de texto, el exponente n = 1/3 para el número de Prandtl, en las correlaciones tipo ley de potencia del número de Nusselt, no describe completamente los fenómenos capturados para el conjunto de situaciones de flujo analizadas en este estudio. (Texto tomado de la fuente)A numerical study was done in order to assess the interrelationship between the nondimensional numbers Reynolds and Prandtl in the heat transfer forced convection around blunt bodies. For each case, two different flow conditions were explored in order to obtain a wide set of separation situations. A parametric study was carried out using five Prandtl numbers, between 0.1 < Pr < 500, and four Reynolds numbers, between 10 < Re < 10000$. The local and average Nusselt number was analyzed in conjunction with the velocity profiles, the pressure coefficient and surface shear stress coefficient. The averaged Nusselt over the studied faces showed a maximum value at Pr = 50 between 10 < Re < 1000. For Re = 10000, the thermal diffusivity was more relevant and the maximum values shifted to Pr = 5, in most of the cases, and Pr = 0.72 and Pr = 0.1 in less situations. From the local behavior was observed the apparition of relative extreme values in the neighborhood of the boundary layer detachment points, where the vortex formation influenced the positioning of these values. It can be inferred from the study that, contrary to what has been established by several authors and textbooks, the assumption for the exponent n = 1/3, in the Nusselt power lay correlations, do not fully describe the phenomena observed in the situations analyzed in this work.MaestríaMagíster en Ingeniería MecánicaTransferencia de calorMecánica de fluidosxvi, 83 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería MecánicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá530 - Física::532 - Mecánica de fluidos530 - Física::536 - Calor620 - Ingeniería y operaciones afines::621 - Física aplicada620 - Ingeniería y operaciones afines::629 - Otras ramas de la ingenieríaAnálisis numéricoNumerical analysisTransmisión del calorProcesamiento de datosHeat - Transmissiondata processingConvección de calor forzadaFlujo externoSeparación de flujoNúmero de ReynoldsNúmero de PrandtlFlujo incompresibleHeat Transfer Forced ConvectionExternal flowFlow separationReynolds numberPrandtl numberLarge Eddy SimulationsIncompressible flowEstudio numerico de la interdepedencia de los numeros adimensionales Nusselt, Reynolds y Prandtl.Numerical assessment of the interdependency of the non-dimensional numbers Nusselt, Reynolds and Prandtl.Trabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMAhmed, G.
