Heat transfer dictates the efficiency of energy and transport systems such as gas turbines, high-speed generators and turbochargers. These are among many applications where heat transfer involves turbulent fluid flow over solid surfaces, but where poor understanding of surface conditions leads to dubious models, suboptimal designs and cost penalties. This project therefore aims to advance our fundamental understanding of heat transfer accounting for the practical surface conditions of roughness, solid-fluid pairing and uneven heating. Building on capabilities that now place systematic data within reach, this project will deliver physics-based models that can robustly predict heat transfer, leading to reduced costs of energy and transport.

热传递决定了能源和运输系统的效率，如燃气轮机、高速发电机和涡轮增压机。在许多应用中，传热涉及固体表面上的湍流流动，但对表面条件的了解不足导致模型可疑、设计次优和成本损失。因此，这个项目的目的是促进我们对传热学的基本理解，考虑到实际的表面条件，如粗糙度、固液配对和不均匀加热。在现有系统数据触手可及的能力基础上，该项目将提供基于物理的模型，这些模型可以有力地预测热量传递，从而降低能源和运输成本。
