Wound ballistics and forensic medicine,dynamo problem has been limited to analytic calculations, numerical modelling and observational studies; experimental validation (the critical test for any theory) of aspects of the theory and experimental studies of laboratory dynamos have been scarce.

https://doi.org/10.1007/978-3-642-20447-0al-symmetric flow is calculated on a staggered grid with a finite-volume method. The conjugate-gradient method with a preconditioner accelerates the approximation. In azimuthal direction a spectral analysis allows a three-dimensional simulation for spherical shells with a wide gap.

On the Possibility of an Homogeneous MHD Dynamo in the Laboratorydynamo problem has been limited to analytic calculations, numerical modelling and observational studies; experimental validation (the critical test for any theory) of aspects of the theory and experimental studies of laboratory dynamos have been scarce.

Dynamo Action Due to Ekman Layer Instability number .* defined using the Ekman layer thickness, exceeds the experimentally measured value of .*. ≃ (or 124.5 for type I). We will focus on the type II travelling wave, which has the smaller critical Reynolds number and so is easier to study numerically.

Saturation Mechanism in a Model of the Karlsruhe Dynamovations show however that volumetric flow rates continue to increase as a function of the applied pressure even when a steady dynamo field is present, which indicates that the velocity profile inside individual spin generators changes in response to the magnetic field.

https://doi.org/10.1007/978-3-642-18962-3g the abrupt brake. Internal diverters will enable the required profile of velocity. The expected flow can act as a dynamo provided its magnetic Reynolds .. number is expected to exceed several tens. The experiment is developing in the Institute of Continuous Media Mechanics of Ural Branch of Russian Academy of Sciences, Perm, Russia.
