03 Multipart Questions Conferences It is proposed to air-cool the cylinders of a combustion chamber by joining an aluminum casing with annular fins ( k= WileyPLUS Sup- port 215 W/m-K) to the cylinder wall k = Collaborations 50 W/m K). The air is at 320 K and the corresponding convection coefficient is 100 W/m2-K. Although heating at the inner surface is periodic, it is reasonable to assume steady-state conditions with a time-averaged heat flux of Chat Browse NBC 1 x 10 W/m2.
