Effect of helicity and rotation on the free decay of turbulent flows [PDF]
, 2008 The self-similar decay of energy in a turbulent flow is studied in direct numerical simulations with and without rotation. Two initial conditions are considered: one non-helical (mirror-symmetric), and one with maximal helicity.

Effect of Fractional Kinetic Helicity on Turbulent Magnetic Dynamo Spectra [PDF]
, 2001 Magnetic field amplification in astrophysics ultimately requires an understanding of magnetohydrodynamic turbulence. Kinetic helicity has long been known to be important for large scale field growth in forced MHD turbulence, and has been recently ...

Large-diameter helical pile capacity – torque correlations [PDF]
Canadian Geotechnical Journal, 2017 Large-diameter helical piles are utilized increasingly to support heavy structures. Both the magnitude of the required installation torque and the pile capacity can be directly attributed to the soil shearing resistance developed over the embedded area of the pile including the shaft and helical plates.

Numerical Modelling of Axially Loaded Helical Piles: Compressive Resistance [PDF]
E3S Web of Conferences, 2021 Helical piles are foundation systems used to support compression, tension, and lateral loads. However, this type of piles was used around the world for more than 25 years. Its behavior, especially in Iraq, is still unknown and scare. The present study is
