A beautiful reminder that physics is everywhere, even in soap
You ’re look at a physique from a paper titled “ visualisation of current pattern past various objects in two - dimensional stream using grievous bodily harm film , ” published in the latest issue ofPhysics of Fluids . ( [ Very ] hi - res version availablehere . ) The generator write : Although many advanced observational flow visualizations , such as mote prototype velocimetry or laser Doppler velocimetry , have been developed and used in fluid dynamics enquiry , the use of flowing soap films has remained as an educational tool and economical visualization proficiency to study fluid - body structure interaction and hydrodynamic instability in two - dimensional fluid flows ....
