An exertion is executed to explicate thermophysical aspects of viscoelastic fluid flow produced by a nonlinearized stretched surface. Here, viscoelasticity is characterized by Casson fluid model and expressed rheologically in momentum equation. Flow attributes of Casson fluid are thoroughly investigated under transversal magnetized field and along with provision of suction/injection to surface. Flow medium is also considered to be porous. Convective heating is supplied to the surface to depict heat transfer change within the flow domain. Nanosized particles are hanged into the Casson fluid to understand the effectiveness of Brownian motion and thermophoretic forces on the diffusion of particles. Generative chemical reactions are also considered to measure mass transport. Initially, flow narrating differential equations for concerning a problem are attained in differential equations and later on transforming into ordinary differential coupled system via similarity approach. Variations in flow associated distributions against involved parameters are divulged through graphical structures. Wall drag, thermal and mass fluxes are also calculated. Credibility of computing results is tested with the aid of comparison with previously published data in limiting sense.

执行一项工作来阐明非线性拉伸表面产生的粘弹性流体流动的热物理方面。在这里，粘弹性由卡森流体模型表征，并在动量方程中用流变学表示。在横向磁化场下以及对地面的抽吸/注入作用下，将彻底研究Casson流体的流动属性。流动介质也被认为是多孔的。对流加热提供给表面，以描绘流域内的传热变化。将纳米尺寸的粒子悬挂在Casson流体中，以了解布朗运动和热泳力对粒子扩散的有效性。生成化学反应也被认为可以测量质量传递。原来，在一个微分方程中实现了与问题相关的流叙述微分方程，随后通过相似性方法转换为普通的微分耦合系统。流量相关分布相对于所涉及参数的变化通过图形结构进行了披露。还计算壁阻力，热通量和质量通量。计算结果的可信度通过与以前发布的数据进行比较的限制来测试。
