Abstract :
Investigations was performed on the influence of using nanoparticles on the heat transference and flow rate of fluids. This test section used consists from copper tube of (1.58 cm) outer diameter, and (1.4 cm) inner diameter, with (150 cm) length. The outside surface tube is electrically heated by a coil made from Nichrome material (Chemical Composition: 20% Cr, 80% Ni and has melting point: 1400 °C) joined to an AC power supply to produce heat flux. Thermocouples sensors were placed along the test section to measure the temperature. a number of nanoparticles with different proportions and different materials was used, such as Nano-iron oxide and nanoscale aluminum in the form of powder and in different proportions. The result showed that the temperature of the test section has transient effect as the time increases the temperature of the test section increase.
