This investigation enlightens the hydrothermal features of chemically reactive nanofluidic transport over an inclined spinning disk. The revolving disk is considered to move freely with uniform angular velocity. The surface of the disk is permeable. The nanofluid flow is considered thermally radiative. Also, the presence of a heat source/sink is included to portray a more realistic outcome. How the permeability feature of the surface affects the hydrothermal integrity has been analyzed in detail. The prime dimensional equations are made dimensionless using appropriate similarity transformation. After then, the spectral quasi linearization method (SQLM) is operated to solve those equations. Residual plots are extracted to exhibit the speediness of the introduced SQLM technique. Several graphs, three-dimensional figures, and tables are rendered to avail the consequences of the underlying parameters. The linear regression slope procedure is included to quantify the enhancement or reduction of the heat and mass transport as well as shear stresses. The outcomes assured that the normalized thickness parameter augments the radial velocity and nanoparticle concentration. Chemical reaction reduces the concentration profile for suction but amplifies for injection. The temperature drops off for suction, while it amplifies for injection. Heat transport drops off for heat source, but heat sink conveys the reverse scenario. Heat source drops down the heat transference at the rate of 0.69874 for injection and 0.8374 for suction. Mass transport amplifies for chemical reaction during injection, while the reverse trend is detected for suction. This investigation has noteworthy applications in the mechanical and chemical engineering process.

考虑热源/热汇存在的可渗透倾斜旋转盘上辐射纳米流体喷射的光谱准线性化模拟

这项研究揭示了化学反应纳米流体在倾斜旋转盘上传输的水热特征。认为转盘以均匀角速度自由运动。圆盘的表面是可渗透的。纳米流体流动被认为是热辐射的。此外,还包括热源/散热器的存在以描绘更真实的结果。已经详细分析了地表的渗透特性如何影响热液完整性。使用适当的相似变换使素数维方程无量纲。然后,使用谱准线性化方法 (SQLM) 来求解这些方程。提取残差图以展示引入的 SQLM 技术的速度。几个图形,三维图形,并呈现表格以利用基础参数的结果。包括线性回归斜率程序以量化热量和质量传输以及剪切应力的增强或减少。结果确保归一化厚度参数增加径向速度和纳米颗粒浓度。化学反应会降低抽吸的浓度分布,但会放大注射。吸入时温度会下降,而注射时温度会放大。热源的热传输下降,但散热器传达了相反的情况。热源以0.69874(注入)和0.8374(吸入)的速率降低传热。在注射过程中,传质放大了化学反应,而抽吸检测到了相反的趋势。
