Abstract: An experimental research was carried out to study the effect of flowing a solid particle with hot air on heat pipe performance, three heat pipes were manufactured with outer and inner diameter of 22.225, 19.8 mm, respectively and with 1000 mm long for both evaporator, condenser and adiabatic sections were (64.5, 34.5,1) cm long, respectively. The three heat pipes were fixed in a wooden box and the cement fly ash was used as a bed particle cross the evaporator part with the hot air, cement fly ash properties were measured experimentally. Tests were done with air velocity range of 3.5-5.5 m/sec and solid particle bed thickness of 2.5, 5 cm, the results show that the Nusselt number was enhanced by 61.5% for the case of 5 cm particle bed thickness and (5.5 m/sec) air velocity with respect to the case of flow of air without solid particle. An acceptable pressure drop will happened for this case which is not exceed (39%).
