Heat transfer capacity of liquids is usually lower than the solids or solids metal compounds. If suspended solid particles are added with liquid it is expected that the heat transport of liquid can be improved. However, there has some major drawbacks because of the nanofluids lack of dispersibility, aggregation, sedimentation and adhesive characteristics of nanofluids with the inner wall of the pipe. These nanoparticles are used to make nanofluids by mixing them with water at different volume fraction of solute. In this experiment 0%, 0.5%, 1% & 1.5% volume concentration TiO2 nanofluid is used. The particle size in the range of 150-280nm. The nanofluids behavior was studied in terms of viscosity, density and thermal conductivity. The viscosity ratio of nanofluids increases with increase in concentration. In this study the thermal conductivity and viscosity will be measured through simulation in Ansys Fluent.
