| Abstract | ||
| Two dimensional flow over single cylinder with different shapes in the free stream are numerically investigated. Consideration is given to the effect of cylinder seven shapes with the same area, and Reynolds number (Re) on heat transfer and flow phenomena. The study has been carried out for Reynolds number between (200-2000). The study discloses that the heat transfer and pressure drop are effected by cylinder shape. The relationship between Nuselt number (Nu) and angle from stagnation point (θ) also pressure coefficient (Cp) and angle from stagnation point (θ) are determined, the new shapes are compared with circular cylinder and the results show that maximum heat transfer be with the shape ( 7 ). | ||
