Nanofluidics and Lab-on-a-Chip Devices

Definition

Numerical simulations are computational techniques used to model and analyze complex physical systems by solving mathematical equations numerically rather than analytically. They allow researchers to predict the behavior of systems, such as nanofluidic devices, under various conditions, enabling deeper insights into processes at the nanoscale. These simulations are essential in understanding fluid dynamics, molecular interactions, and heat transfer in confined geometries, which are pivotal in optimizing lab-on-a-chip devices.
