Recent advances in fluid mechanics have demonstrated that the use of polymer solutions and surfactants can effectively reduce drag in turbulent flows. This phenomenon, which facilitates a decrease in ...

A new study revisits a century-old question about how turbulence starts. The findings could potentially influence not only aircraft engineering but even the design of mechanical heart valves, and ...

The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. This phenomenon is governed by the Navier-Stokes ...
