《使用FLUENT建模热传递》是一份详细介绍如何运用FLUENT软件进行热传递模拟的高级培训资料,由ANSYS公司于2006年发布。FLUENT是一款广泛应用于计算流体动力学(CFD)的软件,能够帮助工程师和科学家分析各种工程和自然现象中的热传递问题。 培训第一天的议程主要涵盖了热传递的基础概念和关键方法。上午的课程包括导热、强迫对流和自然对流的讲座,以及相应的实践教程。导热讲解了在固体和流体中由于分子振动和电子运动导致的热量扩散;强迫对流则关注通过流动流体来传递热量的过程;而自然对流则涉及由于温度差异引起的流体自然流动导致的热传递。 下午的课程重点是辐射和太阳能负载建模,这是理解环境热交换和太阳能影响的关键。辐射是通过电磁波来传递能量的方式,而在FLUENT中建模这一过程对于理解建筑、航空航天或太阳能收集器设计等领域的热性能至关重要。最后的实践教程环节,学员可以应用所学知识解决实际问题,并进行课程总结。 第二天的课程进一步深入,上午的讲座和实践围绕热交换器模型展开,这是工业中常见且重要的设备,用于提高或降低流体的温度。接着,介绍了多孔介质中的热传递,这对于理解和模拟土壤、织物、泡沫等复杂材料的热性能非常有价值。午餐后,课程以一个实践教程和总结结束,确保学员能够将两天所学应用于实际工程问题中。 培训内容全面地概述了热传递的四种基本模式:导热、对流、辐射和相变。能量方程和边界条件是这些模式背后的理论基础,它们在FLUENT软件中被用来建立和求解复杂的热传递模型。通过对这些概念的深入理解和熟练应用,工程师可以精确预测和优化各种系统中的热行为,从而在设计和改进产品时做出数据驱动的决策。

Conduction Heat Transfer
Conduction is the transfer of heat by molecular interaction.
Gases – Molecular velocity depends on temperature. Hot, energetic
molecules collide with neighbors which increases their speed.
Solids – Molecules and the lattice structure vibrate.
Fourier’s Law states that heat flux is proportional to temperature
gradient. Mathematically,

Integration of Fourier’s Law in 1D
For a simple 1D steady state conduction, the temperature profile
through a slab is linear.
This leads to the concept of thermal resistance:
