Abstract

An experimental investigation has been conducted to clarify heat transfer characteristics and effectiveness of a cross flow heat exchanger with bundle of semi-circular tubes. An ambient air and a hot water have been used as an external and internal fluids respectively. Where the tubes are placed in an in-line arrangement. The Reynolds number ranged from about 2x10 4to 16.5x104. The angle of attack (θ) is varied from 0° to 270° and the relative longitudinal pitches (S1/d) from 1.35 to 2.69, while the relative transfer pitche was kept constant (St/d = 1.35). It has been found that the heat transfer in terms of Nusselt number (Nu) and effectiveness (E) varies drastically with the angle of attack (θ) and also with the longitudinal pitches (S1). Correlations have been obtained for (Nu) as functions of (Re) at different (Sy/d) and (θ) and also for (E) as function of capacity ratio Z, St/d, and 0. The results show that the highest values of Nu, E occurred when the angle of attack, (θ) is 270° for all values of (S1/d) at constant (St/d).
