Experimental Investigation of Nano Fluid Effects on Heat Transferring in the Bearing

In this research, effects of Nano powder solution in lubricants as cooler for bearing has been investigated. Experiments have been done once by normal lubricants without any additive and once by adding Nano powder of copper with 99 percent purity in normal lubricant. In these experiments two factor like rotational velocity and radial force have been studied. Temperature has been measured by laser thermometer. Results have shown while the Nano powder is being used, thermal difference between bearing and lubricant has been decreased. This decrease in comparison to normal lubricant has been decreased about 10.7 percent. Because of more friction when the radial load was used the percent of decreasing thermal difference will be increased and with increasing rotation this percent has decreased.
