Furthermore , a numerical filter method is applied to eliminate some undesired short waves generated as the program runs , which prevents the computed results of the numerical model from distortions 在數(shù)值計算中,采用了數(shù)值過濾技術(shù),有效地除去了由于非線性效應(yīng)的相互作用而產(chǎn)生的極小波長諧波,保證了數(shù)值計算的準(zhǔn)確性。
Numerical fluxes considered in the explicit portion of the algorithm were evaluated by an implicit high - order compact scheme to augment stability . meanwhile , an implicit high - order compact numerical filter was used 顯式一邊的空間導(dǎo)數(shù)采用具有較高精度和良好數(shù)值穩(wěn)定性的隱式高階緊致差分格式,同時采用適于低馬赫數(shù)流動計算的隱式高階數(shù)值過濾方法。
