The discovery of Sanal flow choking is a scientific breakthrough and a paradigm shift in the diagnostics of the detonation/hemorrhage in real‐world fluid flow systems. The closed‐form analytical models capable of predicting the boundary‐layer blockage factor for both 2D and 3D cases at the Sanal flow choking for adiabatic and diabatic fluid flow conditions are critically reviewed here. The beauty and novelty of these models stem from the veracity that at the Sanal flow choking condition for diabatic flows all the conservation laws of nature are satisfied at a unique location, which allows for computational fluid dynamics (CFD) code verification. At the Sanal flow choking condition both the thermal choking and the wall‐friction‐induced flow choking occur at a single sonic fluid throat location. The blockage factor predicted at the Sanal flow choking condition can be taken as an infallible data for various in silico model verification, validation, and calibration. The 3D blockage factor at the Sanal flow choking is found to be 45.12% lower than the 2D case of a wall‐bounded diabatic fluid flow system with air as the working fluid. The physical insight of Sanal flow choking presented in this review article sheds light on finding solutions, through in silico experiments in base flow and nanoflows, for numerous unresolved problems carried forward over the centuries in physical, chemical, and biological sciences for humankind.

Sanal Flow Choking:计算流体动力学代码验证和诊断现实世界流体流动系统中的爆炸和出血的范式转变。

Sanal 流动阻塞的发现是科学突破和现实世界流体流动系统中爆震/出血诊断的范式转变。本文对能够预测绝热和绝热流体流动条件下 Sanal 流阻塞的 2D 和 3D 情况下的边界层阻塞因子的封闭式分析模型进行了严格审查。这些模型的美丽和新颖性源于真实性,即在非绝热流的 Sanal 流阻塞条件下,所有自然守恒定律都在一个独特的位置得到满足,这允许计算流体动力学 (CFD) 代码验证。在 Sanal 流动阻塞条件下,热阻塞和壁面摩擦引起的流动阻塞都发生在单个声速流体喉部位置。在 Sanal 流量阻塞条件下预测的阻塞因子可以作为各种 in silico 模型验证、验证和校准的可靠数据。发现 Sanal 流动阻塞处的 3D 阻塞因子比以空气为工作流体的壁面非绝热流体流动系统的 2D 情况低 45.12%。这篇评论文章中提出的 Sanal 流阻塞的物理洞察力揭示了通过基流和纳米流的计算机实验来寻找解决方案,以解决几个世纪以来人类物理、化学和生物科学中许多未解决的问题。比以空气为工作流体的壁面非绝热流体流动系统的二维情况低 12%。这篇评论文章中提出的 Sanal 流阻塞的物理洞察力揭示了通过基流和纳米流的计算机实验来寻找解决方案,以解决几个世纪以来人类物理、化学和生物科学中许多未解决的问题。比以空气为工作流体的壁面非绝热流体流动系统的二维情况低 12%。这篇评论文章中提出的 Sanal 流阻塞的物理洞察力揭示了通过基流和纳米流的计算机实验来寻找解决方案,以解决几个世纪以来人类物理、化学和生物科学中许多未解决的问题。
