Abstract EN
In this paper, a laboratory prototype was designed and built to test the forcedconvection heat transfer from out surface of hollow cylinder with inner porosity20% at different heat fluxes.
The effect of regarding parameters such as Nusselt, Rayleigh and Reynold numbers on heat transfer and the flow character areobserved.
The experimental results shows that local Nusselt number of theexternal cylinder decrease with the reduction of Rayleigh number by 46.7% atmaximum level and 21.7% at minimum level when Rayleigh number decreasefrom 4 ∗ 107 to1 ∗ 107.
While it increase with Reynolds number by 21.8% atmaximum level and 40% at minimum when Reynolds number rise from 500 to2200 (minimum to maximum).
