Based on nano-fluid made of lithium bromide(LiBr) aqueous solution

nano-particles and its relevant dispersants

the stability and thermal-physics properties of the nano-fluid were researched through a contrastive experimental method that surface tension and boiling temperature of nano-fluid and pure LiBr aqueous solution were tested respectively. It was discovered experimentally that the surface tension of solution added nano-particles reduces significantly and granularity of the nano-fluid decreases obviously through temperature processing. The nano-particles almost completely dissolves into LiBr aqueous solution

simultaneity the solution shows better stability and both its surface tension and boiling temperature both have a decrease compared with pure LiBr aqueous solution. The study shows that best composition nano-fluids is related to the types and contents of nano-particles and relevant dispersants.Through strict temperature processing

the nano-fluid has a better engineering application than the pure LiBr solution as its good stability and better thermal-physics properties.
