Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

ABSTRACT The navigation and control of untethered magnetic robots (UMRs) within soft brain tissue critically depend on their ability to maintain synchronized rotation under applied rotational magnetic fields. The fundamental upper limit of this magnetic synchronization, known as...

Influence of fin geometry on heat transfer and friction in plate fin heat exchangers: a CFD approach

Abstract Plate fin heat exchangers (PFHEs) are widely recognized for their compact design and high thermal efficiency, making them a popular choice in various heat transfer applications. Some common types of geometries which are used in the case of PFHEs are rectangular fins, tri...
