Abstract

The gas dynamics of single-phase nonreacting fluids whose thermodynamic states are close to vapor-liquid saturation, close to the vapor-liquid critical point, or in supercritical conditions differs quantitatively and qualitatively from the textbook gas dynamics of dilute, ideal gases. Due to nonideal fluid thermodynamic properties, unconventional gas dynamic effects are possible, including nonclassical rarefaction shock waves and the nonmonotonic variation of the Mach number along steady isentropic expansions. This review provides a comprehensive theoretical framework of the fundamentals of nonideal compressible fluid dynamics (NICFD). The relation between nonideal gas dynamics and the complexity of the fluid molecules is clarified. The theoretical, numerical, and experimental tools currently employed to investigate NICFD flows and related applications are reviewed, followed by an overview of industrial processes involving NICFD, ranging from organic Rankine and supercritical CO2 cycle power systems to supercritical processes. The future challenges facing researchers in the field are briefly outlined.

致密蒸汽和超临界流体的非理想可压缩流体动力学

热力学状态接近汽液饱和、接近汽液临界点或处于超临界条件下的单相非反应流体的气体动力学与教科书上的稀薄理想气体的气体动力学在数量和质量上都有所不同。由于非理想流体的热力学特性，可能出现非常规的气体动力学效应，包括非经典的稀释冲击波和马赫数在稳定等熵膨胀过程中的非单调变化。本综述为非理想可压缩流体动力学（NICFD）的基本原理提供了一个全面的理论框架。阐明了非理想气体动力学与流体分子复杂性之间的关系。综述了目前用于研究非理想可压缩流体动力学流动和相关应用的理论、数值和实验工具，随后概述了涉及非理想可压缩流体动力学的工业过程，包括从有机朗肯和超临界二氧化碳循环发电系统到超临界过程。简要概述了该领域研究人员未来面临的挑战。

期刊介绍： The Annual Review of Fluid Mechanics is a longstanding publication dating back to 1969 that explores noteworthy advancements in the field of fluid mechanics. Its comprehensive coverage includes various topics such as the historical and foundational aspects of fluid mechanics, non-newtonian fluids and rheology, both incompressible and compressible fluids, plasma flow, flow stability, multi-phase flows, heat and species transport, fluid flow control, combustion, turbulence, shock waves, and explosions. Recently, an important development has occurred for this journal. It has transitioned from a gated access model to an open access platform through Annual Reviews' innovative Subscribe to Open program. Consequently, all articles published in the current volume are now freely accessible to the public under a Creative Commons Attribution (CC BY) license. This new approach not only ensures broader dissemination of research in fluid mechanics but also fosters a more inclusive and collaborative scientific community.
