Temperature calculations inside body during treatment by capacitive heating device

Integratable Programmable Capacitive Device

Collisionless heating in capacitive discharges enhanced by dual-frequency excitation.

We discuss collisionless electron heating in capacitive discharges excited by a combination of two disparate frequencies. By developing an analytical model, we find, contrary to expectation, that the net heating in this case is much larger than the sum of the effects occurring when the two frequencies act separately. This prediction is substantiated by kinetic simulations, which are also in exc...

Enhanced temperature uniformity by tetrahedral laser heating

Temperature profile on a spherical sample that is heated by laser beams in various geometries while processed in vacuum is analyzed. Sample heating by one or four laser beams was considered. An analytical expression was derived for directional sample heating cases. It suggests an enhanced temperature uniformity over the samples when heated with four diffuse laser beams arranged in a tetrahedral...

Flow and heat transfer inside a new diversion-type gas heating device

The present paper characterizes ethylene glycol flow and heat transfer inside a new diversion-type gas heating device. A two-dimensional (2-D) natural convection heat transfer model was built and solved by the finite volume method with unstructured body-fitted grids. The numerical model was first validated through temperature comparison with the experimental measurements in a conventional devic...

Capacitive properties of body tissues.

The electric capacity of various tissues surrounding the heart has been investigated in living dogs, using frequency ranges from 10 to 10,000 c.p.s. Electrode polarization, a serious source of error in such measurements, has been corrected for. Discussion of our results and of resistivity data previously obtained in body tissues proves that the electric properties of body tissues are primarily ...
