High Voltage, EarlyView.ABSTRACT Quickly and accurately obtaining the internal temperature distribution of a transformer plays a key role in predicting its operating conditions and simplifying the maintenance process. A reasonable equivalent thermal circuit model is a relatively reliable method of obtaining the internal temperature distribution.

Nusselt number scaling in tokamak plasma turbulence [PDF]
Physics of Plasmas, 2005 Anomalous heat transport caused by ion temperature gradient (ITG) driven turbulence in tokamak plasmas is evaluated from numerical simulations of the two-dimensional (2D) partial-differential equations of the ITG model and of a reduced 1D version derived from a quasilinear approximation.
