Coupled, Multi-Physics Problems

Nanotechnology is the study and use of materials and structures that are on the nanometer scale, and involves the use of materials with unique properties and behaviors that are not found in conventional materials. Coupled, multi-physics problems related to nanotechnology involve understanding the interactions between multiple physics phenomena at the nanoscale and how they could affect the performance of a device. Such problems may involve the interactions between heat transfer, fluid flow, and electrical charge, as well as other physical phenomena. Heat transfer is an important factor in nanotechnology, as the small size of these structures means that heat can easily be dissipated. This can lead to problems such as overheating and unwanted thermal effects. In order to understand the effects of heat transfer at the nanoscale, researchers must consider the effects of convection, radiation, and conduction. Fluid flow is also an important phenomenon to consider when investigating the properties of nanostructures. The small size of these structures can lead to a variety of fluid flow effects, including capillary forces, surface tension, and slip flows. Analyzing the effects of these phenomena at the nanoscale can help develop better understanding of how nanostructures interact with their environment. The electrical charge of nanostructures is also an important factor to consider. Understanding the effects of electric fields and currents on nanostructures can help researchers design better devices. Electric charge can affect the performance of nanostructures, and can lead to problems such as charging and discharging.
