Visualisasi aliran fluida (Fluid flow visualization)

, ,
Anda pasti pernah mendengar ungkapan "satu gambar bisa bernilai seribu kata". Hal ini nampaknya juga berlaku untuk dunia mekanika fluida. Jika kita berbicara masalah mekanika benda padat, kita dapat dengan mudah menggambarkanya dengan hukum…

Momentum Analysis of fluid flow

,
In fluid mechanics, we are dealing with highly "squishy" material, unlike solid material which is easily modeled using relatively simple mathematical relationships. The nature of fluid flow complexity makes the "higher-order" mathematical modeling…
