1. Heat flow in the combustion chamber

The evaluation of heat flows on the wall of a combustion chamber can be carried out in a similar way to that of the blades (cf. ).

Figure 1 shows the heat flows acting on the chamber wall. Those entering are due to radiation R 1 and hot gas convection C 1 , while the outer side of the wall yields heat flow to the convective cooling system C 2 , by radiation R 2 towards the envelope due to the large surfaces involved and the low value of the outer wall temperatures. Heat exchange between the two faces of the wall K 1 – 2 ...
