GENERAL MODEL OF RADIATIVE AND CONVECTIVE HEAT TRANSFER IN BUILDINGS: PART I: ALGEBRAIC MODEL OF RADIATIVE HEAT TRANSFER

open access: yesActa Polytechnica, 2019
Radiative heat transfer is the most effective mechanism of energy transport inside buildings. One of the methods capable of computing the radiative heat transport is based on the system of algebraic equations.

Numerical investigation of heat losses through cascaded fully open cavity receiver at high temperatures up to 500°C [PDF]

open access: yesE3S Web of Conferences, 2019
In solar thermal systems, especially for high concentration applications, natural convection and radiation contributes a significant fraction of energy loss. Its characteristics hence need to be understood to improve system efficiency.

The Effect of a Teflon Insulation Layer Installed Inside the Pump on the Insulation of a Centrifugal Pump for Transporting Liquid Hydrogen

open access: yesEnergies
One of the most important goals in developing centrifugal pumps for liquid hydrogen transport is to minimize the temperature rise of the working fluid caused by internal and external heat sources during operation. In this paper, as part of our evaluation
