sometimes the surface tension of nanofluid increases and sometimes decreases
with the nanoparticles concentration increasing.There is no constant behavior for that.Is there any useful test about that.
الشد السطحي للموائع النانوية يعتمد على حجم وتركيز الدقائق النانوية حيث بزيادة التركيز قديزداد الشد السطحي ولكن هذا يعتمد على قوى الجذب بين الحبيبات النانوية(قوى فاندفالز )حيث اذا كانت كبيرة سوف يقل الشد السطحي للمادة بزيادة التركيز
يحدث التوتر السطحي بسبب قوه قوى التجاذب (قوى التماسك) بين جزيئات السائل فاذا كانت قليله سوف يزداد الشد السطحي بنقصان التركيز .
Its depending on the degree of attraction between the nanoparticuls and the fluid used ,which is based on the chemical structure and the presence of functional groups of both nanoparticule and fluid, if it was a stronge attraction then the fluid will be high viscos leads to high surface tension, the opposit is right.
Dr,
The relation between the surface tention and concentration is oppsit.
Depending on the degree of attraction between the nanoparticles and the fluid used.if it was a stronger attraction than the fluid will be highly viscous leads to high surface tension.

surface tension for nanoflud depends on the size and cocentration of nanoparticles, the increasing of concentration may lead to increase of surface tension. but it also depends on the degree of attraction between the nanoparticles and fluid used, if the degree of attraction was strong then the relation become oppisit
Surface tension of nanoparticles depends on the size and concentration of nanoparticles, with an increased concentration of surface tensile stress, but this depends on the forces of attraction between the nanoparticles where if large the surface tension of the substance will be reduced by increasing concentration
The cohesive forces between molecules down into a liquid are shared with all neighboring atoms. Those on the surface have no neighboring atoms above, and exhibit stronger attractive forces upon their nearest neighbors on the surface.
