CFD | Direct Numerical Simulation, DNS

在計算流體力學（CFD）的最高境界——直接數值模擬 (Direct Numerical Simulation, DNS) 中，耗散率（Dissipation Rate）是衡量能量如何從大尺度渦流傳遞至微小尺度並最終轉化為熱能的核心物理量。 Direct Numerical Simulation 1. Incompressible Flow 物理表達式 (不可壓縮流)在不可壓縮流（Incompres

高空西風帶與三圈環流 | Three-cell circulation and upper-level westerly winds

全球大氣環流現象一個非常經典且有趣的全球大氣環流現象：無論是在北半球還是南半球，中高緯度的高空（對流層中上部到平流層）基本上都被強勁的西風所統治。這聽起來可能有點反直覺，畢竟地面上有信風（東風）、中緯度西風和極地東風，但到了高空，情況就變得出奇地統一。以下是造成這種「全球高空皆西風」局面的核心邏輯： 1. 根本驅動力：南北溫差太陽輻射在赤道最強，極地最弱。這導致赤道大氣的溫度遠高於極地
