Abstract EN
A numerical analysis aiming to gain an understanding of the physical behavior for thermal and fluid flow attributes in tubes fitted with quadruple plain and modified twisted tapes inserts (which all occupy an equal volume) for the turbulent reynolds number range (5,000 to 20,000) is carried out.
the tube inserted with quadruple modified twisted tapes showed better thermal enhancement when compared with plain tube and tubes induced with quadruple plain twisted tapes.
the simulation included modification on tapes as cuts with; circular, half circle on side, triangular and rhomboidal shapes.
the obtained results showed a maximum increase of 31.12% is observed in the nusselt number by using tube fitted with quadruple circular cuts twisted tapes inserts than that observed with the plain tube.
and the higher friction factor obtained of the tube fitted with quadruple circular cuts twisted tapes inserts are up to 32.65% than that of the plain tube.
