Full TextAbstract
An experimental investigation has been carried out to study the pressure drop of a nanofluid through a horizontal copper tube. The tube is heated by an electrical heating coil wrapped around it. Also, the rheological properties of the used nanofluid have been studied. Nanodiamond particles which belong to carbon family have been chosen as dispersed particles. Because of high viscosity of the chosen base fluid (Engine oil - SAE 20 W 50), the Reynolds number is low and thus flow regime is laminar. Pressure drop of pure engine oil and also engine oil-nanodiamond nanofluids flowing inside the tube has been measured by a high precision differential pressure transmitter (PMD-75). Experimental results showed that the pressure drop of nanofluid substantially increases compare to pure engine oil. Furthermore, the pressure drop increases with the increase of nanodiamond concentration in the fluid.
