Характер изменения лучистого потока на стенку теплообменника внутри кольцевого канала при наличии в нем перфорированного экрана

The influence of the degree of perforated and emissivity screen and the wall of the inner channel of the heat exchanger on the radiation flux to the outer tube of the heat exchanger. Calculations were made resolvent zonal method Surinov-Gebhart. The formulas defining the medium resolution and medium angular coefficients of the system. It is shown that with increasing degree of blackness and perforating radiant flux decreases.
