| dc.description.abstract | 本論文中,我完成了繪圖處理晶片(GPU)版本的理想三維磁流體之演算程序。在其中利用包含了磁場內稟限制條件下的傳輸方式(constraint transport)的立體邊角方向性傳輸(corner transport upwind)之演算法,來演算流體及感應方程式。
星際物質通常是由熱氣體與分子雲構成。在此我將展示以聲光效應為基礎的星系形成之機制 | zh_TW |
| dc.description.abstract | We have implemented graphic processing unit (GPU) solvers to the 3D ideal magnetohydrodynamcis (MHD) equations. Corner-transport upwind(CTU) scheme including constraint-transport(CT) method is adopted to evalu¬ate the hydro and induction equation.
Usually, the interstellar medium consists of the hot gas and the molecular cloud. In this thesis we will present the mechanism based on sonoluminescence for the formation of the star. | en |
