* 层流控制需要过渡预测方法，这些方法可以解释在实施或开发过程中遇到的各种表面质量和自由流环境条件。本文提出了一种变N因子转捩预测方案，它考虑了层流实际应用中的许多重要物理机制。该方法是基于线性不稳定放大因子（n因子）的相关性，但也借鉴了感受性理论和生长调节剂。对于外部因素，不容纳在可变N-因子框架内，其他相关模型被认为是。
*Laminar flow control requires transition-prediction methods that can account for the varied surface-quality and free-stream environmental conditions encountered during implementation or development. A variable N-factor transition-prediction scheme is presented, which accounts for many of the physical mechanisms important for the practical applications of laminar flow. The approach is based on correlations with linear instability amplification factors (n-factors), but also draws on receptivity theory and growth modifiers. For external factors that are not accommodated within the variable N-factor framework, other empirical-correlation models are considered.
