The heat and mass transfer on time dependent hydrodynamic squeeze flow of Jeffrey nanofluid across two plates over permeable medium in the slip condition with heat generation/absorption, thermal radiation and chemical reaction are investigated. The impacts of Brownian motion and thermophoresis is examined in the Buongiorno's nanofluid model. Conversion of the governing partial differential equations to the ordinary differential equations is conducted via similarity transformation. The dimensionless equations are solved by imposing numerical method of Keller-box. The outputs are compared with previous reported works in the journals for the validation of the present outputs and found in proper agreement. The behavior of velocity, temperature, and nanoparticles concentration profiles by varying the pertinent parameters are examined. Findings portray that the acceleration of the velocity profile and the wall shear stress is due to the squeezing of plates. Furthermore, the velocity, temperature and concentration profile decline with boost in Hartmann number and ratio of relaxation to retardation times. It is discovered that the rate of heat transfer and temperature profile increase when viscous dissipation, thermophoresis and heat source/sink rises. In contrast, the increment of thermal radiation reduces the temperature and enhances the heat transfer rate. Besides, the mass transfer rate decelerates for increasing Brownian motion in nanofluid, while it elevates when chemical reaction and thermophoresis increases.
研究了热生成/吸收、热辐射和化学反应条件下，具有滑移条件的可渗透介质中两板间随时间变化的 Jeffrey 纳米流体的热质传递。在 Buongiorno 的纳米流体模型中检查了布朗运动和热泳的影响。通过相似变换将控制偏微分方程转换为常微分方程。通过 Keller-box 的数值方法求解无量纲方程。将输出结果与期刊中以前报道的工作进行比较，以验证本输出结果，并发现它们非常吻合。通过改变相关参数来检查速度、温度和纳米颗粒浓度分布的行为。研究结果表明，速度分布的加速和壁面剪切应力是由于板的挤压所致。此外，随着哈特曼数和松弛时间与延迟时间之比的增加，速度、温度和浓度分布会下降。发现当粘性耗散、热泳和热源/汇增加时，传热速率和温度分布增加。相反，热辐射的增加会降低温度并提高传热速率。此外，当化学反应和热泳增加时，纳米流体中布朗运动的增加会降低传质速率，而当热泳增加时，传质速率会增加。
