Turbulence in the cooling system of a fusion machine such as the blanket is especially complex and its understanding and prediction is one of the major challenges facing the reactor design. The ...

Abstract: Turbulent fluid flows are characterized by a wide spectrum of spatial and temporal scales. Unfortunately, the cost of resolving these scales with Direct Numerical Simulation (DNS) grows ...

Using HLRS’s Hawk supercomputer, University of Stuttgart scientists have for the first time produced high-resolution simulation data characterizing the transition from low to high Reynolds numbers in ...

The spatio-temporal evolution of wall-bounded turbulence is characterized by high nonlinearity, multi-scale dynamics, and chaotic nature, making its accurate prediction a significant challenge for ...

Researchers uncover the long-hidden process that helps explain why the Sun's corona can be vastly hotter than the solar surface that emits it. Researchers have uncovered a previously hidden heating ...

Researchers have uncovered a previously hidden heating process that helps explain how the atmosphere that surrounds the Sun called the “solar corona” can be vastly hotter than the solar surface that ...
