How much stress do pipes undergo when a liquid flows through them, and how does it depend on the degree of curvature of the pipe?
A novel measurement technique has been developed to visualize the fluid flow and distribution within two droplets levitated and coalesced in space using fluorescence-emitting particles. This technique enabled the estimation ...
