Laser/PFC project study · 8 October 2026

激光/PFC 项目学习 · 2026 年 10 月 8 日

Jet theory chain · J01 → J04 → laser/PFC

射流理论链 · J01 → J04 → 激光/PFC

The required teaching order completes generic jet mechanics before introducing laser/PFC sources. The physical causal order still starts with the laser. We first solve mechanics with a declared source, then derive that source from optical heating and phase thermodynamics.

必学顺序先完成通用射流力学,再引入激光/PFC 源。实际因果顺序仍从激光开始。先使用声明源求解力学,再从光学加热和相变热力学推导该源。

Inputs held explicit

明确保留的输入

J01 · Pressure impulse, cavity energy and symmetry breaking

J01 · 压力冲量、腔体能量与对称性破缺

Integrate Rayleigh energy/time, derive spatial pressure impulse and anisotropy; separate radial and jet speed.

积分 Rayleigh 能量/时间,推导空间压力冲量及不对称性;区分径向与射流速度。

Supplied cavity/source, liquid properties and boundary geometry.

给定腔体/源、液体物性与边界几何。

J02 · Moving interfaces, jet formation and geometric focusing

J02 · 运动界面、射流形成与几何聚焦

Close potential-flow interface motion; recover radial signs; solve flux-limited and pressure-limited focusing.

闭合势流界面运动;还原径向符号;求解限流量及限压力聚焦。

Initial surfaces/potential, gas law or pressure history, all boundaries.

初始表面/势、气体规律或压力历程及全部边界。

J03 · Jet transport, capillary instability and breakup

J03 · 射流输运、毛细失稳与破碎

Derive slender conservation, capillary spectrum and finite-flight growth; distinguish threshold from actual pinch.

推导细长守恒、毛细增长谱及有限飞行增长;区分阈值与真实夹断。

Formed jet profile, finite mass/length, noise and continuing supply.

已形成射流轮廓、有限质量/长度、噪声及持续供给。

J04 · Jet impact, observed pressure and finite limits

J04 · 射流冲击、观测压力与有限极限

Derive receiver force/impulse and acoustic impact; define pressure observation and finite conditional bounds.

推导接收体受力/冲量及声学冲击;定义压力观察及有限条件界限。

Arrival field, receiver response, fixed area/time observation and energy budget.

到达场、接收体响应、固定面积/时间观察与能量预算。

What “close the chain” means

“完成理论链”的含义

Each stage states its governing equations, closure laws, initial/boundary data, conserved quantities and output definitions. The analytic controls are solved and numerically checked. State and budgets are passed to the next stage. A specified nonlinear free-surface geometry still requires a spatial solution; a table of models is not an experimental verification or a universal closed-form maximum.

每阶段明确支配方程、闭合规律、初始/边界数据、守恒量及输出定义。解析对照已求解并数值核验,状态与预算传到下一阶段。指定非线性自由表面几何仍需空间求解;模型表格不是实验验证,也不是通用闭式最高值。

The substantial arrangement follows the earlier pressure-limit chapter: start with a soluble control, derive the refinement, calculate its implications, identify its transition, and end with a multi-part problem. Original chapters and accepted solutions are retained. Every displayed formula is followed by its own physical variable map, and every reference answer begins with the original formulas.

完整安排参考早期压力极限章节:从可解对照开始,推导改进,计算其含义,确定阶段转换,最后以多部分综合题收尾。原章节及已接受解答保留。每个显示公式后都有相应物理变量图,每个参考答案先列原始公式。

After J04: specialize the supplied source and compare architectures

J04 之后:特化给定源并比较结构

L01 becomes the bridge to optical deposition, heat flow and finite PFC phase inventory. The subsequent project route keeps PFC in a finite water-droplet stamp, the primary PFC-containing liquid layer below film/PVC, and PFC embedded in hydrogel. Both direct liquid-to-film and intact-PVC-mediated loading remain. Compare mechanisms and both output envelopes without forced early selection.

L01 成为连接光学沉积、热流与有限 PFC 相存量的桥梁。后续项目路线保留有限水滴印章中的 PFC、主要薄膜/PVC 下含 PFC 液层及水凝胶嵌入 PFC。液体直接作用于薄膜及完整 PVC 介导载荷均保留。比较机制及两类输出范围,不强制提前选一个分支。

Harmonic acoustic forcing is not a prerequisite detour. Linear capillary perturbation in J03 and the arrest wave in J04 serve jet survival and impact prediction directly. Each chapter asks one brief synthesis after a comprehensive worked calculation; new chapters remain pending until understanding is demonstrated.

简谐声学驱动不是必修绕行。J03 的线性毛细扰动和 J04 的制动波直接服务于射流存续与冲击预测。每章在综合计算后要求一次简短综合回答;理解得到展示之前,新章保持待完成。
