“Cooling flows” in DIFA classrooms

Published 2018 September 23

ABSTRACT

The gas temperature in some areas of DIFA classrooms N and M drops inward by about a factor of two within the central 100 cm radius. The human body cooling time drops over the same region from about 100 yr down to about 10^-2 yr. Infrared images show holes coincident with icy cold lobes. The observational situation is reported here and may be discussed in the near future, together with the implications for any heat source which can balance radiative cooling and save our lives.

Keywords: radiative transfer – cooling flows – IR maps
