NANOFLUIDS: PROSPECTS FOR APPLICATIONS IN HEAT SOURCES
The application of nanofluids in thermal systems has great prospects, since the addition of nanoparticles gives a significant increase in the coefficient of thermal conductivity. The nanofluids thermal conductivity depends on the thermal conductivity coefficient of the base liquid and the volume nanoparticles fraction. It is assumed that the heat transfer coefficients and thermal conductivity are in direct correlation. Computational studies show that the increase in the heat transfer coefficient on the coolant side by adding nanoparticles in the coolant volume concentration of up to 10% is up to 23 % in the convective tube bundle. The increase in the heat transfer coefficient on the coolant side in the fire tube is up to 23 % when changing the volume concentration of nanoparticles in the range up to 10 %.
