TL;DR: In this article, the effect of the Reynolds number and Hartmann number on the fluid temperature during a transient varies greatly depending on their initial and steady state values, in some cases the peak transient temperature can be orders of magnitude greater than either the initial or steady state value.
Abstract: Unsteady-state, laminar, forced-convection heat transfer of an electrically conducting fluid subjected to a transverse magnetic field, flowing through a horizontal parallel plate channel has been analytically investigated for the short circuit condition using the method of characteristics. The transient is caused by a step change in the axial pressure gradient or magnetic field. Both the entrance region and fully developed heat-transfer regions were considered for a fluid with constant wall temperature. The velocity profile was assumed uniform throughout the channel at any instant of time for the purpose of calculating convective heat transfer only, but the temperature profile distribution depends 011 both the axial and transverse linear coordinates. Numerical computations were carried out which indicate that the effect of the Reynolds number and Hartmann number on the fluid temperature during a transient varies greatly depending on their initial and steady-state values. In some cases, the peak transient temperature can be orders of magnitude greater than either the initial or steadystate value.

TL;DR: All tissues and organs were reconstructed as three-dimensional unstructured triangulated surface objects, yielding high precision images of individual features of the body, which greatly enhances the meshing flexibility and the accuracy in comparison with the traditional voxel-based representation of anatomical models.
Abstract: The objective of this study was to develop anatomically correct whole body human models of an adult male (34 years old), an adult female (26 years old) and two children (an 11-year-old girl and a six-year-old boy) for the optimized evaluation of electromagnetic exposure. These four models are referred to as the Virtual Family. They are based on high resolution magnetic resonance (MR) images of healthy volunteers. More than 80 different tissue types were distinguished during the segmentation. To improve the accuracy and the effectiveness of the segmentation, a novel semi-automated tool was used to analyze and segment the data. All tissues and organs were reconstructed as three-dimensional (3D) unstructured triangulated surface objects, yielding high precision images of individual features of the body. This greatly enhances the meshing flexibility and the accuracy with respect to thin tissue layers and small organs in comparison with the traditional voxel-based representation of anatomical models. Conformal computational techniques were also applied. The techniques and tools developed in this study can be used to more effectively develop future models and further improve the accuracy of the models for various applications. For research purposes, the four models are provided for free to the scientific community.
