Abstract
In this work studied is the possibility of fluid pumping using capillary forces in the capillary pumped loop. Experimental and theoretical studies have been performed to understand the phenomena associated with heat transfer in porous structure of the evaporator. The capillary effect was studied during operation of two different capillary porous structures with two different working fluids, namely water and acetone. The results gave a foundation for a new concept of modern evaporator for waste heat recovery that supports the fluid pumping in the thermodynamic cycle. The results shows that evaporator filled by capillary wick made of Ni-Cu sintered porous material can produce the pressure difference up to 1.63Â kPa at the heat rate input of 100Â W.
