Abstract
In this paper, a Numerical investigation of developing laminar flows with forced convection through a compact circular pipe has been done using water-Al2O3 nano-fluid. Uniform heat flux (UHF) and the steady-state has been maintained at the wall in each model. Throughout the numerical experiments, Nano-fluid models were made by Alumina volume fraction and were processed under the Re=1050. A single-phase fluid model was determined by nano-fluid thermal and physical properties calculation, whereas the Two-phase model, i.e., granular mixture model was defined in 100nm diameter. The results show that the Al2O3 volume fraction increases, the heat transfer rate and Nusselt number increases. All the numerical simulations were developed in ANSYS FLUENT. The result displays the rise of thermal transfer from the volume fraction concentration.
