Encountering of entropy generation is meaningful while investigating the energy loss during the operational mechanical system. In particular, the flow of fluid experiencing friction drag and due to which a significant amount of heat transfer occurred. Thus, the thermodynamic system energy conversion is one of the measures of the lost available work and is known as irreversibility. Avoiding of such energy loss can be minimized by introducing the concept of hybridization during the liquid dynamics. This work is initiated to formally characterize and address the significance of irreversible process during the typical Homann flow of viscoelastic liquid. The flow with heat and mass balance aspects are further characterize with the inclusion of thermophoretic and Brownian motion factors. The flow configuration is interpreted in terms of gravitationally affected vertical cylindrical disk, for a better understanding of the impact of irreversible processes, more physical effects in terms of heating source/sink, chemical reaction and solar thermal radiation. New physical impacts are described numerically in terms of flow speed temperatures, nanoparticle volume fraction, displacement thicknesses and entropy generation. Perturbation method is utilized for the reduction of the fourth-order mathematical equation for reducing the problem in to well-posed from ill-posed status. The numerical analysis is carried out by applying one of the built-in commands while using MATLAB software. The buoyancy force factor enhanced the liquid speed, and the concentration of the liquid was determined with uplifted conduct for higher values of chemical reaction parameters. The overall entropy rate is reduced as the Brinkman number and magnetic parameter are increased. The heat transfer flow is increased by internal heat generation. Higher Prandtl and Schmidt numbers significantly affected the isotherms and volume fraction contours.

在研究运行机械系统过程中的能量损失时，遇到熵的产生是有意义的。特别是，流体流动受到摩擦阻力，因此发生了大量的热传递。因此，热力学系统能量转换是衡量可用功损失的指标之一，被称为不可逆性。通过在液体动力学过程中引入杂化的概念，可以最大限度地减少这种能量损失。这项工作的启动是为了正式表征和解决粘弹性液体的典型 Homann 流中不可逆过程的重要性。流动与热和质量平衡方面进一步表征了热泳和布朗运动因子。流动配置根据受重力影响的垂直圆柱形圆盘进行解释，以便更好地理解不可逆过程的影响，在热源/汇、化学反应和太阳热辐射方面的更多物理效应。新的物理影响以流速温度、纳米颗粒体积分数、位移厚度和熵产生的形式进行数值描述。扰动方法用于简化四阶数学方程，以将问题从病态状态简化为优态。数值分析是通过在使用 MATLAB 软件时应用内置命令之一来进行的。浮力因子提高了液体速度，对于较高的化学反应参数值，液体的浓度是通过提升行为来确定的。随着 Brinkman 数和磁参数的增加，总熵率会降低。 传热流量通过内部热量的产生而增加。较高的 Prandtl 和 Schmidt 数显著影响等温线和体积分数等值线。
