Abstract : The present thesis deals with numerical investigations of thermal-hydraulic behavior of laminar mixed (combined free and forced) convective flow of nanofluid in the entrance region of a horizontal annulus. A thermal boundary condition of uniform heat flux at the inner wall and an adiabatic outer wall was selected. The basic numerical procedure adopted in the present study is the SIMPLER algorithm. The study was carried out numerically for laminar flow of nanofluid consisting of water as base fluid and Ag-TiO2 as nanoparticles. The ratio of Ag to TiO2 is maintained as 1:3. The numerical code used was indirectly verified by experimental and numerical results of many authors who later on conducted similar investigations. A reasonably good grid independency was achieved by using 48×48 grid in r-θ plane with Δz= 0.25 mm. An annulus with 10 mm inner diameter and 20 mm outer diameter with 1000 mm axial length has been used in the present study. The numerical investigations were carried out in the following range of parameters: 105< Gr<5x106, 200
