fluent中的rate exponent怎么設置

rate exponent：specifies the rate constant for the reactant species in the reaction.

the rate exponent is the exponent on the

reactant or product concentration。

rate exponent，速率指數。

當反應是可逆基元反應是，速率指數數就等于化學(xué)計量比。

當反應是不可逆反應時(shí)，生成物的速率指數就等于0.

當反應不是基元反應時(shí)，速率常數是實(shí)驗中確定的經(jīng)驗值，去查數據庫。

另外，給個(gè)建議，fluent遇到這類(lèi)問(wèn)題，去查自帶的幫助文檔，新版和舊版（網(wǎng)上找）的幫助文檔，對照著(zhù)看。

fluent中的rate exponent怎么設置

目測應該是反應速率方程里的一個(gè)指數，具體是什么看一下幫助吧，然后了解一下你所模擬的化學(xué)反應的動(dòng)力學(xué)。
