Resumen
Este estudio muestra que los nanofluidos ternarios (Cu-Al₂O₃-TiO₂/agua) ofrecen una transferencia de calor superior en sistemas de discos giratorios. Los campos magnéticos y el medio poroso impactan el flujo y el comportamiento térmico para una gestión térmica avanzada.
Área de la Ciencia:
- Dinámica de fluidos
- Transferencia de calor
- Nanotecnología
Sus antecedentes:
- La comprensión del flujo de fluidos y la transferencia de calor es crucial para la gestión térmica en sistemas industriales y electrónicos.
- Los nanofluidos ternarios ofrecen potencial para mejorar las propiedades termofísicas en comparación con los nanofluidos simples o híbridos.
- Las geometrías de flujo complejas, como los discos giratorios y expansibles en medios porosos, requieren modelos avanzados.
Objetivo del estudio:
- Investigar el flujo y la transferencia de calor magnetohidrodinámico 3D de un nanofluido ternario (Cu-Al₂O₃-TiO₂/agua) entre discos coaxiales giratorios y expansibles.
- Analizar los efectos del campo magnético, medio poroso, disipación viscosa, relajación térmica, expansión del disco y condiciones de contorno de deslizamiento.
- Comparar el rendimiento de los nanofluidos ternarios con los nanofluidos híbridos y simples.
Principales métodos:
- Ecuaciones gobernantes transformadas en ecuaciones diferenciales ordinarias no lineales utilizando transformaciones de similaridad.
- Solución semi-analítica obtenida a través del Método de Análisis de Homotopía (HAM).
- Simulación de campo 3D completa utilizando COMSOL Multiphysics (FEM) para validación.
Principales resultados:
- Los nanofluidos ternarios demostraron capacidades superiores de transferencia de momento y calor.
- El campo magnético y la resistencia del medio poroso redujeron las velocidades pero aumentaron la acumulación térmica.
- La rotación y expansión del disco mejoraron tanto la velocidad como el número de Nusselt.
- Los parámetros de deslizamiento disminuyeron la fricción superficial y la transferencia de calor; el número de Eckert aumentó la resistencia al flujo y la temperatura.
Conclusiones:
- El estudio valida la efectividad de los nanofluidos ternarios para mejorar las aplicaciones de transferencia de calor.
- Los hallazgos ofrecen información valiosa para optimizar la gestión térmica en sistemas de ingeniería complejos.
- La investigación proporciona un análisis novedoso del comportamiento de los nanofluidos ternarios en configuraciones intrincadas de discos giratorios y expansibles.

4.2K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.
