中文摘要 | 在本篇文章,我們在系統為兩個非理想混合CSTR串聯,反應型式為 - γa = kCa/( 1 + KCa)²之起動-操作圖中,找到一個在第二個槽會發生輸出多重輸出穩態區域。經過分析,新對應區域是由於第一槽之多重輸入穩態區域與第二槽之多重輸出穩態區域互相重疊所致。此新對應區域不只使第二個槽會發生輸出多重穩態,也會使得動-操作圖中的最大穩態數目與其分佈改變。本文也用了模擬結果來驗證。 |
英文摘要 | In this paper, we find a new mapped region of the output steady-state multiplicity of the second CSTR in the start-up diagram of two non-ideal mixing CSTRs in series where the reaction rate expression is - γa = kCa/( 1 + KCa)². By virtue of our analysis, this new mapped region is caused by the fact that the exact input multiplicity region in the non-ideal mixing of the first CSTR overlaps with the exact output multiplicity region of the non-ideal mixing of the second CSTR. This new mapped region not only comes about multiplicity in the second CSTR but also changes the maximum number of steady states and its distribution in the start-up diagram. Simulated results are used to demonstrate our works. |
