考慮均相和非均相反應(yīng)和熱輻射效應(yīng),研究了非均勻熱源對(duì)納米流體在膨脹板上流動(dòng)的影響。用Corcione關(guān)系式描述了納米流體的動(dòng)力黏度和有效熱導(dǎo)率的關(guān)系。根據(jù)這個(gè)關(guān)系式得出,導(dǎo)熱是由布朗運(yùn)動(dòng)進(jìn)行的。通過(guò)相似變換減少了與納米流體的能量、動(dòng)量和濃度有關(guān)的控制方程,并進(jìn)行數(shù)值求解。研究了內(nèi)熱源參數(shù)、納米流體的體積分?jǐn)?shù)、輻射參數(shù)、均相反應(yīng)參數(shù)、磁場(chǎng)參數(shù)、非均相參數(shù)和Schmidt數(shù)等對(duì)熱和流體流動(dòng)的影響。最后,考慮研究中的有效參數(shù),改進(jìn)了Nusselt數(shù)的關(guān)系式。結(jié)果表明,隨著非均相參數(shù)和均相反應(yīng)參數(shù)的變大,濃度曲線變稀。結(jié)果表明,Nusselt數(shù)與內(nèi)部熱源參數(shù)之間存在反向關(guān)系。
