您要查找的是不是：
- TVD性質(zhì)TVD property
- 指出:1.對于Riemann間斷分解,Euler方程的解和Riemann不變量都沒(méi)有TVD性質(zhì),因此不能將TVD格式自然推廣;We have come to the follwing conclusions: 1. For Riemann problem, the solution of Euler equation and the Riemann invariants do not have TVD property, so it is unreasonble to extend TVD scheme naturally to system of quasilinear equation in the meaning of section 2A.
- 采用有限體積法和TVD性質(zhì)的差分格式相結合求解軸對稱(chēng)歐拉方程的方法對高速列車(chē)通過(guò)隧道時(shí)在隧道出口區域產(chǎn)生的微壓波問(wèn)題進(jìn)行了數值研究.The finited volume method and a total variation diminishing(TVD)numerical scheme were used to solve the axisymmetric Euler equation,which was utilized to simulate the Micro Pressure Wave discharged from the tunnel exit when a train entered a tunnel at high speed.
- 性質(zhì)nature
- 為適應較高馬赫數計算，對人工粘性中的壓力(溫度)感測因子進(jìn)行改進(jìn)，使其具有類(lèi)TVD性質(zhì)，并有效地抑制不真實(shí)的數值振蕩，拓展了中心格式的適用范圍，使格式更具魯棒性。In order to apply the central scheme to higher Mach number flows, the sensor about pressure or temperature aremodified with some TVD-like properties.
