Pocket wind tunnel · iOS 口袋风洞 · iOS

Wind, made visible. 让风,看得见

Sketch any shape — an airfoil, a building, a paper airplane — and BreeZ traces every streamline, vortex and pressure pocket around it in real time. A real Lattice‑Boltzmann fluid solver, running entirely on your device. 画下任何形状——机翼、建筑、纸飞机—— BreeZ 会实时算出风从它身边流过的每一条线、每一个涡和每一处压力。 一个真正的 LBM 流体求解器,全程在你的设备上运行。

What you can do 你可以做什么

Three minutes in, you'll have your own little wind experiment. 三分钟,你就能搭出属于自己的小型风洞实验。

Draw, then watch the wind 先画形状,再看风

Freehand, line, curve or Bezier. Drop a preset, import an outline from a photo, or rotate the angle of attack with the sheet. 手绘、直线、曲线或贝塞尔。也可以放预设、从照片提取轮廓、或者用面板调整迎角。

Four ways to look at it 四种观察方式

Streamlines, smoke, vorticity, pressure, velocity. Critical points (stagnation / separation) are labelled automatically. 流线、烟流、涡量、压力、速度场可任意切换。滞止点与分离点会自动标注。

Real solver, not a video loop 真求解器,不是循环视频

A D2Q9 Lattice‑Boltzmann simulation runs on Metal. Drag and lift readings update as you move things around. D2Q9 格子玻尔兹曼方法跑在 Metal 上。物体移动时阻力 / 升力实时更新。

Save, share, export 保存、分享、导出

Export a clean still or a 5‑second clip. Optional info chin shows the wind speed, angle, drag and lift used in the run. 导出整洁的静态图或 5 秒短片。可选的信息条会附上当时的风速、角度、阻力和升力。
