High-order polynomial expansions

Nektar++ can use high-order polynomial bases on each element to provide faster convergence rates compared with linear finite elements.

The wake passing effect in LPTs with Nektar++

This blog highlights some research efforts aimed at simulating the wake passing effect in a low pressure turbine cascade, analysed over the entire operating range. The incoming disturbances modify the physical transition mechanism on the suction surface, giving rise to complex flow phenomena.
