Heat transfer of the TiO2/water nanofluid in an annulus of the finite rotating cylinders

Study on the heat transfer of TiO2/water nanofluid flows inside annulus of the finite rotating cylinders was done numerically. Inner shaft and outer tube were rotated in co-rotating and counter-rotating direction. The k-epsilon turbulent model and the Mixture-multiphase model were used to treats the...
