in this investigation the silicate nano structure of mcm-41 has been used for the production of nanofluid.the particles have negligible heat conductivity and therefore by their dispersion in a base fluid likewater, it is possible to study the increase of heat conductivity due to the brownian motion effects. in thiswork a suitable apparatus for the measurement of heat conductivity has been built...
