Abstract EN
This research presents an experimental study of forced convection heat transfer for laminar steady flows in a duct filled with saturated porous media glass balls.The heater model consists of a circular cylinder , square cylinder and triangular cylinder .The experimental work was studied the effect of changing heater section on forced convection heat transfer with selected values of heat supply ( 2455W/m2 ).The experiments were carried out for Reynolds number ( 1094 ≤????≤ 1510 ).The experimental results showed that the surface temperature was highest for circular section type than square section then triangular section.Also, the average Nusselt number increased with increased Reynolds number and the large value for Nusselt number was for circular cylinder than square cylinder then triangular cylinder .
The experimental results showed that the best improvement in forced convection heat transfer were when using porous media for the circular cylinder (63%), the Square cylinder (71%) and the triangular cylinder (74%).
Also, in the present work, empirical correlations were obtained and comparison was made between the present experimental with the available previous studies a good agreement was obtained
