Abstract In this paper, a simplifying approach for calculating the radiant energy is achieved using the concept of net radiation heat transfer and provides an
easy way for solving a variety of situations. This method has been applied to calculate the net radiation heat transfer between two long concentric
semi-cylinders. Then this method used to calculate reduction heat transfer when radiation shields with temperature-dependent emissivity applied
between these objects. Moreover, using this method the percentage reduction in heat transfer between two surfaces was calculated. The findings
reveal that, one radiation shield with lower emissivity can reduce the net heat transfer even… More >
