供熱冷卻系統(tǒng)的優(yōu)化設(shè)計(jì)必須考慮非線性過程的熱輻射。本文研究了銅-水納米流體在伸縮圓筒上的Eyring-Powell磁熱輻射的混合對(duì)流動(dòng)力學(xué)�？紤]非線性熱輻射和熱滑移條件,建立了能量守衡模型,分析了表面摩擦系數(shù)和換熱速率等流動(dòng)參數(shù)對(duì)流體特性的影響。不采用現(xiàn)有的研究方法,應(yīng)用最近的譜準(zhǔn)線性化方法求解耦合非線性邊界值問題。計(jì)算結(jié)果表明,增大納米粒子的體積分?jǐn)?shù)、熱輻射參數(shù)和熱源參數(shù)可增強(qiáng)溫度分布。速度滑移參數(shù)和流體材料參數(shù)增大了表面摩擦力。對(duì)比分析了極限情況下的數(shù)值結(jié)果和文獻(xiàn)結(jié)果,結(jié)果表明:采用本文研究方法計(jì)算結(jié)果達(dá)到同等精度。
