DIE GRAFIESE VOORSTELLING VAN STROOMLYNE VAN 'N JOUKOWSKI-PROFIEL MET BEHULP VAN 'N REKENAAR

open access: yesScientia Militaria, 2012
Where in the study of aerodynamics it is often necessary to represent flow patterns graphically, the writer illustrates how a desk calculator with plotting facilities and limited memory space can be used to this end. As an example he supplies a programme

A New Capacitance Sensor for Measuring the Void Fraction of Two-Phase Flow Through Tube Bundles

open access: yesSensors, 2020
Evaluating the two-phase flow parameters across tube bundles is crucial to the analysis of vibration excitation mechanisms. These parameters include the temporal and local variation of void fraction and phase redistribution. Understanding these two-phase

Zonal flow as pattern formation [PDF]

open access: yesPhysics of Plasmas, 2013
Zonal flows are well known to arise spontaneously out of turbulence. We show that for statistically averaged equations of the stochastically forced generalized Hasegawa-Mima model, steady-state zonal flows, and inhomogeneous turbulence fit into the framework of pattern formation. There are many implications.
