Cylindrical heat transfer
WebMay 22, 2024 · The cylindrical coordinates don't make any difference. The physical boundary condition is that the radial heat flux on each side of the boundary is the same. That means k 1 d T d r 1 = k 2 d T d r 2 where k 1 and k 2 are the thermal conductivities of the materials on each side of the boundary. WebThe heat transfer by conduction through hollow cylindrical shape is given by, Q = t1 − t2 ln( r2 r1) 2πKL t 1 - t 2 ln ( r 2 r 1) 2 π K L. Where, t1 t 1 = Inner surface temperature. t2 t 2 = Outer surface temperature. r1 r 1 = Inner radius of cylinder. r2 r 2 = Outer radius of cylinder.
