Summary: The main purpose of this study is to develop a mathematical model for the steady three-dimensional boundary layer flow of incompressible non-Newtonian Cross nanofluid over a bidirectional stretching surface. The Buongiorno nanofluid model and Cattaneo-Christov heat flux model are employed in this study. The motion of fluid flow is induced due to the bidirectional stretching surface embedded in Darcy-Forchheimer porous media. The modeled partial differential equations are reduced to ordinary differential equations using appropriate transformation, and then numerically solved using the Runge-Kutta Fehlberg scheme and shooting method.

Summary: In this study, we investigated the influence of entropy generation on Maxwell hybrid nanofluid over a cylinder in the presence of non-linear thermal radiation and Cattaneo-Christov heat flux. We compared the solutions obtained using numerical method (NM) and homotopy perturbation method (HPM) and found that HPM provided more accurate and reliable outcomes. The results showed that higher magnetic parameter led to lower fluid velocity, higher heat generation parameter improved temperature profiles, and Darcy-Forchheimer number and temperature time relaxation parameter decreased Nusselt number. This type of flow problems is important for improving blood flow in blood vessels.

Summary: The lack of synchronization between offshore wind farms (OWFs) and onshore grids in high voltage DC systems is caused by the stochastic nature of wind energy, resulting in various system disturbances, grid contingencies, power loss, and frequency instability. This research focuses on frequency stability analysis and proposes a dynamic coordination control technique for a Double Fed Induction Generator (DFIG) integrated with a hybrid multi-terminal HVDC (MTDC) system consisting of OWFs. Line commutated converters (LCC) and voltage source converters (VSC) are utilized in the suggested control method to ensure frequency stability. An adaptive neuro-fuzzy inference approach is employed for accurate wind speed prediction to further enhance frequency stability. The proposed HVDC system can integrate multiple distributed OWFs with the onshore grid system, and the control strategy is designed based on this concept. To ensure the transient stability of the HVDC system, the DFIG-based OWF is regulated by a rotor side controller (RSC) and a grid side controller (GSC) at the grid side using STATCOM. The performance of the devised HVDC (MTDC) is evaluated in MATLAB/SIMULINK by considering different parameters such as frequency, wind power, rotor and stator side current, torque, speed, and power, and the experimental results are compared with a conventional optimal power flow (OPF) model to validate the performance.

Summary: Motivated by the thermal importance of feeble electrically conducting nanofluids and their flow controls in many industrial and engineering applications, this study comprehensively investigates the electro-magneto-hydrothermal and mass aspects of convective non-homogeneous flows of alumina-based pure water nanofluids Al2O3-H2O over a horizontal flat surface. The study adopts the Buongiorno's approach with the inclusion of Brownian motion and thermophoresis diffusive phenomena, and the numerical results show that the nanofluid temperature is significantly enhanced with porosity factors, nanoparticles' loading, convective heating strength, and thermophoresis process. However, the porosity factors and nanoparticles' loading exhibit a slowing-down impact on the nanofluid motion. Importantly, the nanoparticles' loading and porosity factors contribute to an improvement in the strength of the surface viscous drag forces, while the induced electromagnetic field shows a reverse viscous frictional impact.
