Predicting hydraulic fracture propagation more accurately

Researchers at EPFL have developed a new model to calculate hydraulic fracture propagation. Acclaimed for its accuracy by experts, the model better predicts fracture geometry and the energy cost of hydraulic fracturing—a ...

A 127-year-old physics riddle solved

He solved a 127-year-old physics problem on paper and proved that off-centered boat wakes could exist. Five years later, practical experiments proved him right.

Turbulence meets a shock

This may come as a shock, if you're moving fast enough. The shock being shock waves. A balloon's 'pop' is shock waves generated by exploded bits of the balloon moving faster than the speed of sound. Supersonic planes generate ...

Nano drops explode 19th century theory

Droplets emanating from a molecular "nano-tap" would behave very differently from those from a household tap 1 million times larger—researchers at the University of Warwick have found. This is potentially crucial step for ...

A smoother ride over troubled waters

Boating through choppy waters can be an exciting but physically exhausting experience. Now researchers at Utah State University's Splash Lab are taking steps toward the design of an inflatable speedboat that absorbs wave ...
