The purpose of this paper is to study the two-dimensional micropolar fluid flow with conjugate heat transfer and mass transpiration. The considered nanofluid has graphene nanoparticles.

Governing nonlinear partial differential equations are converted to nonlinear ordinary differential equations by similarity transformation. Then, to analyze the flow, the authors derive the dual solutions to the flow problem. Biot number and radiation effect are included in the energy equation. The momentum equation was solved by using boundary conditions, and the temperature equation solved by using hypergeometric series solutions. Nusselt numbers and skin friction coefficients are calculated as functions of the Reynolds number. Further, the problem is governed by other parameters, namely, the magnetic parameter, radiation parameter, Prandtl number and mass transpiration. Graphene nanofluids have shown promising thermal conductivity enhancements due to the high thermal conductivity of graphene and have a wide range of applications affecting the thermal boundary layer and serve as coolants and thermal management systems in electronics or as heat transfer fluids in various industrial processes.

Results show that increasing the magnetic field decreases the momentum and increases thermal radiation. The heat source/sink parameter increases the thermal boundary layer. Increasing the volume fraction decreases the velocity profile and increases the temperature. Increasing the Eringen parameter increases the momentum of the fluid flow. Applications are found in the extrusion of polymer sheets, films and sheets, the manufacturing of plastic wires, the fabrication of fibers and the growth of crystals, among others. Heat sources/sinks are commonly used in electronic devices to transfer the heat generated by high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light-emitting diodes to a fluid medium, thermal radiation on the fluid flow used in spectroscopy to study the properties of materials and also used in thermal imaging to capture and display the infrared radiation emitted by objects.

Micropolar fluid flow across stretching/shrinking surfaces is examined. Biot number and radiation effects are included in the energy equation. An increase in the volume fraction decreases the momentum boundary layer thickness. Nusselt numbers and skin friction coefficients are presented versus Reynolds numbers. A dual solution is obtained for a shrinking surface.

The purpose of this study is to explore reshoring drivers and barriers from a Swedish manufacturing perspective.

This paper is a case study, including four Swedish manufacturing companies, with focus on drivers and barriers from the context of the Swedish manufacturing industry. A literature review of previously established drivers and barriers is used to map out the empirical findings and thereby identify potential gaps between the current body of literature and drivers and barriers from a Swedish manufacturing context.

The findings of the study suggest that quality issues continue to be one of the strongest reshoring drivers. Except for product quality, quality is also connected to host country’s infrastructure, communication and service. The supply chain perspective is a source of several drivers and is identified as a perspective often overlooked in offshoring decisions. Barriers related to firm specifics were more elaborately discussed by the companies, especially concerning calculation of location decision and the need to invest in resources, which allows for a higher level of capacity at the home country facility.

The study develops a structured table of reshoring drivers and barriers which can serve as a base for future research. Future research on the calculation of location decisions is deemed as a crucial step to further understand reshoring and aid companies in the decision-making process.

The drivers and barriers identified in the study can give practitioners insight into reshoring from the perspective of the Swedish manufacturing industry and thus aid in future manufacturing location decisions. The table of drivers and barriers can also be important to understand how Sweden can strengthen its competitive advantage and motivate more companies to reshore manufacturing.

This is one of only few papers from the Nordic countries and also one of few case studies examining reshoring in manufacturing companies.
