    摘要:

    探討了求解不可壓流動問題的控制體有限元方法,提出了流線FCBI構(gòu)造插值函數(shù)的方法,,并與傳統(tǒng)FCBI和推廣FCBI方法進(jìn)行比較,。選擇方腔流動和S型管道流動兩個(gè)經(jīng)典算例,,分析討論了3種插值函數(shù)在求解不同流動問題時(shí)的共性與特性,。結(jié)果表明:對對流占優(yōu)的流動問題,尤其是流動較為復(fù)雜的對流占優(yōu)問題,,流線FCBI插值函數(shù)能更好地描述單元中速度的分布,,較其他兩種插值函數(shù)更容易獲得穩(wěn)定的收斂解;對非對流占優(yōu)的流動問題,,當(dāng)單元Re小于5時(shí),,3種插值函數(shù)均能獲得較精確的計(jì)算結(jié)果,但當(dāng)單元Re數(shù)較高時(shí),,3種插值函數(shù)的精度均較低,。

    Abstract:

    Control volume finite element method to solve incompressible flow problems was investigated. The streamline FCBI method was built and compared with the original FCBI and general FCBI method. Lid-driven cavity flow and S-channel flow were chosen as the test cases. The similarities and differences among the three interpolation functions were discussed according to the analysis. The results showed that for convection-dominated flow, especially with complex performances, the Streamline FCBI method could better describe the velocity distributions in the element and achieve more stable converged results. For convection-diffusion problems, the precision of all the methods were low when element Re was high. From the analysis that for convection-diffusion problems, it is concluded that good results can be achieved by using FCBI methods when element Re is less than 5.
