This paper presents the finitely extensible nonlinear elastic-Peterlin (FENE-P) fluid model to analyze how polymeric fluid affects drag and heat transfer over a magnetized stretching surface. The FENE-P is one of the viscosity models used to study the behavior of polymeric fluids. The governing boundary layer equations based on physical laws are transformed into a similar form using appropriated transformation. To discuss the impacts of polymers and magnetic fields on flow and heat transfer, the resulting equations are numerically solved using the shooting method, and the outcomes are presented graphically. The role of magnetic fields and polymers as drag-reducing and heat transfer enhancing agents is also thoroughly discussed.

Analysis of magneto-hydrodynamic flow of classical non-Newtonian fluid, Reiner-Philippoff fluid, over magnetized plate is conducted numerically in this article. The mathematical model incorporates the non-linear stress deformation behavior of Reiner-Philippoff fluid and set of Maxwell’s equations to discuss the behavior of non-Newtonian fluid in a magnetic field. Boundary layer equations are obtained assuming the Reynolds and magnetic Reynolds numbers to be large enough for magnetic and momentum boundary layers to have developed. The correlation expressions for skin friction and magnetic flux on the surface for different flow and magnetic field parameters are developed by performing linear regression on numerical data. Stability analysis is conducted as well to analyze the effects of magnetic field and fluid nature on the stability of the flow.

The present article investigated the unsteady flow of a nanofluid past an isothermal magnetized plate emanating from a moving slot. This unique form of unsteady boundary layer flow is analogous to stretching/shrinking sheet problems subject to the direction of motion of the slot. Governing partial differential equation can be reduced into a similar form using the Blasius–Rayleigh–Stokes variable. The consequences of the movable slot and magnetic field on flow and heat transfer of nanofluid are examined by solving the problem numerically. The behavior of the magnetic field in the presence of nanoparticles is also examined. Effects of the magnetic field upon the existence of dual solutions for the specific range of moving slot parameter are also studied in detail.

In this study, we investigate the unsteady flow of a micropolar fluid past a magnetized stretchable/shrinkable sheet. Our research aims to analyze the effects of magnetic field, moving slit, and various parameters on the velocity, magnetic, and microrotation profiles of the fluid. By applying the Blasius–Rayleigh–Stokes variable, we derive ordinary differential equations from the partial differential equations that define the problem. We solve the transformed set of equations using the shooting method and obtain dual solutions. Our findings indicate that skin friction decreases with increasing values of the microrotation parameter and magnetic interaction parameter. We also observe that the magnetic interaction parameter enhances the microrotation of molecules. Overall, our study provides valuable insights into the behavior of unsteady flows in micropolar fluids and sheds light on the impact of various parameters on dual solutions.

This chapter examines the causes of failure in a Web-based information system development project and finds out how complexity can lead a project towards failure. Learning from an Information System Development Project (ISDP) failure plays a key role in the long-term success of any organization desirous of continuous improvement via evaluation and monitoring of its information systems (IS) development efforts. This study reports on a seemingly simple (but only deceptively so) failed ISDP to inform the reader about the various complexities involved in ISDPs in general, and in developing countries in particular. An existing framework from contemporary research is adopted to map the complexities found in the project under study and the critical areas, which lead to the decreased reliability and failure in Web-based information system development, are highlighted.
