“…The effect of entropy generation and irreversibility ratio on the 3D flow of OBF is analyzed by Mburu et al [3] in the presence of retardation-relaxation viscous dissipation. The effect of relaxation-retardation viscous dissipation on the NF flow of 3D rotating OBF is illustrated by Nayak et al [4]. The theoretical treatment of the radiative stream of OBF was examined by Khan et al [5] with microorganisms past an exponentially stretching sheet.…”

The current paper explores the three-dimensional flow of an Oldroyd-B liquid with the impact of a magnetic dipole that occurred by stretching a flat surface placed in the plane with a linear velocity variation in two directions containing motile gyrotactic microorganisms. Using proper similarity transformations, the governing equations are reduced into nonlinear coupled ordinary differential equations (ODEs). The ODEs are then solved using Runge–Kutta-Fehlberg (RKF) method. The training, testing, and validation processes are carried out in parallel to adapt neural networks and calculate an approximate solution for the considered model. This helps to reduce the mean square error (MSE) function by Levenberg–Marquardt backpropagation. The efficiency of the suggested backpropagated neural networks methodology has been demonstrated by utilizing outcomes such as MSE, error histograms, correlation and regression. Results reveal that the heat transport augments for increased Biot number values. The mass transport declines for improved chemical reaction rate parameter values. A higher Peclet number will result in a lower motile diffusivity and result in a decline in the micro-organism’s density profile. For the least value of Mu and gradient, better convergence of the findings can be achieved with better network testing and training.

The thermally developed flow of nanoparticles due to bidirectional moving space has been presented numerically. The additional impact of heat source and sink are also incorporated for enhancing the heat transfer rate. The copper and aluminum nanoparticles are selected for enhancing the thermal diffusion system. The thermal stability of nanoparticles is carefully addressed. The moving surface allows the shrinking and stretching phenomenon. The system of resulting equations with nonlinear nature is numerically swapped via shooting technique with help of MATLAB software. The dual numerical simulations for the thermally radiative problem with external heating phenomenon are being performed. It is noted from results that thermal stability of nanoparticles is more stable in the upper branch of shrinking/stretching surface. The presence of heat source provides extra heat and improves the thermal transportation phenomenon which is more progressive in upper branch. The enhancement in temperature profile due to copper nanoparticles is more stable as compared to aluminum nanoparticles. Moreover, the increasing change in the velocity is resulted upon increasing the rotation constant. The obtained results reflect applications in thermal sciences, heating systems, energy production, solar applications, nuclear reactions, biomedical applications, etc.

PurposeThe major goal of this article is to investigate flow and thermal aspects of Oldroyd B with hybrid nanostructure subject to a radially stretched surface under the influence of low and moderate Prandtl numbers.Design/methodology/approachThe non-dimensional governing equations are solved considering BVP4C in MATLAB as instrumental.FindingsEntropy generation effect is analyzed. Radial velocity and entropy generation exhibit opposite effect in response to amplified relaxation and retardation time parameters in case of both low and moderate Prandtl numbers. Augmented relaxation and retardation time parameters controls heat transfer rate.The results show that increasing the aspect ratio increases both the average Nusselt and entropy generation numbers for each value of the Prandtl number, while increasing the prandtl number decreases both. There is also a minimum value for the entropy generation number at a given relaxation and retardation parameter.Research limitations/implicationsAssume that the Oldroyd B fluid is dispersed with hybrid nanostructure in order to ameliorate thermal conductivity of Oldroyd B fluid so as to make it as best coolant.Practical implicationsThe low range of Prandtl number comprising particles of air, gas, etc. and moderate range of Prandtl number comprising particles of honey, thin motor oil, or any non-Newtonian liquid. The hybrid nanofluid is radiative in nature. Also, the effects of significant physical parameters on entropy generation are highlighted. The entropy generation number intensifies due to the rise in temperature difference parameter at low/moderate Prandtl number effectively. Entropy minimization can lead to the amelioration of available energy thereby enhances the efficiency of several thermal systems.Originality/valueThis article's primary goal is to investigate the flow and thermal aspects of Oldroyd B with a hybrid nanostructure subject to a radially stretched surface under the influence of low and moderate Prandtl numbers.
