Understanding turbulent heat transfer with practical surface conditions

点击翻译按钮获取中文摘要

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.
