How to pronounce "numerical diffusion""numerical diffusion" in a sentence

Translationmobile phoneMobile

  • 數(shù)植擴散
  • 數(shù)值擴散

Examples

  • The characteristic approximation is used to handle the convection part along the direc - tion of fluid namely characteristic direction to ensure the high stability of the method in approximating the sharp fronts and reduce the numerical diffusion ; the mixed finite element spatial approximation is employed to deal with diffusion part and approximate the scalar unknown and the adjoint vector function optimally and simultaneously ; in order to preserve the integral conservation of the method , we introduce the modified characteristic method
    該方法對方程的對流部分沿流體流動的方向即特征方向離散以保證格式在流動的鋒線前沿逼近的高穩(wěn)定性，消除數(shù)值彌散現(xiàn)象；對方程的擴散部分采用最低次混合有限元方法離散、同時以高精度逼近未知函數(shù)及未知函數(shù)的梯度；為保證方法的整體守恒性，在格式中引入修正項
  • The new method is a combination of characteristic approximation to handle the convection part , to ensure the high stability of the method in approximating the sharp fronts and reduce the numerical diffusion , a smaller time truncation is gained at the same time , and a mixed finite element spatial approximation to deal with the diffusion part , the sealer unknown and the adjoint vector function are approximated optimally and simultaneously
    此方法即為對方程的對流項沿流體流動的方向即特征方向進行離散，從而保證格式在流動鋒線前沿逼近的高穩(wěn)定性，消除了數(shù)值彌散現(xiàn)象，并得到了較小的時間截斷誤差；另一方面，對方程的擴散項采用混合元離散，可同時高精度逼近未知函數(shù)及其伴隨向量函數(shù)，理論分析表明，此方法是穩(wěn)定的，具有最優(yōu)的l ~ 2逼近精度。
