我们创建了一个名为“Snowpeak白马村陆地站”的户外娱乐设施，集商店、餐厅、咖啡馆和户外活动于一体，旨在刺激长野县白马村的经济发展。用地周围的树林里有木制拖车房住箱，游客可以享受露营和豪华野营的乐趣。大屋顶的造型设计旨在映射白马村三座山峰的轮廓。此外，还根据树枝和雪花的形状，使用小直径木材设计了一个木结构框架。利用类似篷布使用的织物将空间分割成不同区域，并在墙壁上排列了带有树皮的木制百叶窗，创造出室内却能体验“野外郊游”的空间感。

Journal of Applied Mathematics and Physics 2022年第10期10卷 3121-3142页

作者： Korekazu ueyama Osaka University Toyonaka Japan

By applying a boundary condition for vorticity [1] in addition to that for velocity, a velocity distribution on a flat plate set in a parallel homogeneous flow has been numerically obtained through a one-way calculation from surface to infinity, without the “matching” procedure between an analysis from surface to infinity and that from infinity to surface. The numerical results obtained were in excellent agreement with those by Howarth [2]. The usage of the boundary condition for vorticity has raised the accuracy of velocity distribution near a plate’s surface and made it possible to realize the one-way calculation from surface to infinity.
