What data do you have? W/m3 is heat generated by volume of wall, considering thickness of wall.

the combustor is cubic and it's dimension is
X= 9 cm (length), Y= 16 cm (height), Z= 16 cm (width).

property of material wall:
Cp= 870 j/kg.k, thermal conductivity= 0.6 w/m.k, density= 2400 kg/m3.
thickness of wall= 5cm.

I am not sure but i hope this will help.

Just calculate heat generated by m*cp*(del)T J
1 J = Watt/sec

Multiply by time in which u want to have heat generated.
And divide it by volume.

Hope that works.
