Abstract
This paper demonstrates the augmentation of nano-fluid heat transfer in circular pipe. In this experimental study, nano-fluid of Al2O3/water flow through the circular tube for different mass flow rate (60LPH, 75LPH, 90LPH) Water was used as base fluid in this experiment. Magnetic stirrer and digital ultrasonic water cleaner were used to prepare the homogeneous mixture to disperse 45 nm of Al2O3 nano particle in the base fluid pipe at a particle concentration of 0.05 per cent. Nano fluid was passed through the copper tube for different mass flow rate. Similarly, Water was also passed through the same tube for the same condition. The outcomes from the both experiment was compared with each other. It revealed that higher heat transfer was achieved by nano fluid compared to water. Rate of heat transfer was 30 percent increased by incorporating nano particles in the base fluid.
