摘要：

In presented analysis the stagnation point flow of hybrid nanomaterial is addressed. Comparative study of nanomaterial (using CNTs) with hybrid nanomaterial (CNTs + CuO) is discussed. Gasoline oil is treated as baseliquid. Characteristics of heat transfer are studied via convection and viscous dissipation. Entropy production and Bejan number analysis are emphasized. Governing flow field expressions (PDEs) are obtained and transformed into ODEs via adequate transformations. These ODEs are then solved via shooting method using RK-4 algorithm (bvp4c technique). Behaviors of velocity, entropy production rate, temperature and Bejan number are examined via influential parameters. Comparison of baseliquid, nanomaterial and hybrid nanomaterial is visualized graphically. Nusselt number and skin friction coefficient during flow of baseliquid, nanomaterial and hybrid nanomaterial are numerically evaluated under involved physical parameters.
