摘要：

Thermal and hydrodynamic behavior of circumferentially grooved capillary pumps was studied to describe their operation under different operating conditions and geometries. Permanent speed, capillary limit, reactivation capacity, and presence of non-combustible gases in the circuit were studied and analyzed. An experimental test bench was built for different capillary pumps, and acetone was used as the working fluid. Electrical resistances connected to the capillary pumps were used to apply the power. The results showed that the capillary pumps utilized functioned satisfactorily to a power of 30W and heat flow of up to 1.3 W/cm2. It was further determined that that the presence of non-condensable gases did not affect the functioning of the pumps utilized.
