Two-phase radiative/conductive equilibrium in AGN and GBH

, 2000
We determine simple analytical conditions for combined radiative and thermal equilibrium between the X-ray emitting plasma and cold reprocessor in active galactic nuclei (AGN) and galactic black holes (GBH). These conditions determine the pressure at the

Capacity of a cooling system with active chilled beams at different air flow rates [PDF]

E3S Web of Conferences
The accuracy of dimensioning heating, ventilation and air conditioning systems (HVAC) becomes very important in the designing and construction of nearly-zero energy building (NZEBs). Over-dimensioned HVAC systems on one hand are an investment issue or on
