1、传热学是研究由于温度差而引起的热量传递规律的科学，是几乎渗透到现代工业各个领域的一门技术基础学科。这门学科虽然是在上个世纪 20 年代才开始形成独立的体系，但是由于其广泛的应用背景，其研究内容的深度、广度在近半个世纪以来得到了飞速的发展。目前传热传质学已在传统主体工业改造和新兴尖端工业的迅速发展中扮演着重要的角色；在未来超高集成化的电子器件冷却、航天器的热防护和热控制等高技术领域也起着十分重要的作用。传热的基本方式有热传导、热对流和热辐射三种。实际传热过程一般都不是单一的传热方式，如火焰对炉壁的传热，就是辐射、对流和传导的综合，为了分析方便，人们在传热研究中把三种传热方式分解开来，然后再加以综

6、括浮力定律和浮体稳定性在内的液体平衡理论，奠定了流体静力学的基础。到 15 世纪，达芬奇的著作谈到水波、管流、水力机械、鸟的飞翔原理等问题；17 世纪，帕斯卡阐明了静止流体中压力的概念。但流体力学尤其是流体动力学作为一门严密的科学，却是随着经典力学建立了速度、加速度，力、流场等概念，以及质量、动量、能量三个守恒定律的奠定之后才逐步形成的。流体力学主要研究在各种力的作用下，流体本身的状态，以及流体和固体壁面、流体和流体间、流体与其他运动形态之间的相互作用。探究流体本身的静止状态和运动状态，以及流体和固体界壁间有相对运动时的相互作用和流动的规律。在生活、环保、科学技术及工程中具有重要的应用价值。F
