Modeling of Turbulent Convective Heat-Transfer Characteristics in a Concentric Annular Channel

Experimental Investigation on Heat Transfer of Silver-Oil Nanofluid in Concentric Annular Tube

In order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. Silver-oil nanofluid prepared by Electrical Explosion of Wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. The average size...

A Review of Concentric Annular Heat Pipes

A detailed description of a concentric annular heat pipe (CAHP) operation is presented in low to moderate temperature ranges (50–200◦C). The steady-state response of a CAHP to various heat fluxes in the evaporator and condenser sections are discussed. Two-dimensional mathematical modeling of the fluid flow and heat transfer in the annular vapor space and the wicks are described. The fundamental...

CFD Study of the Turbulent Forced Convective Heat Transfer of Non-Newtonian Nanofluid

Comparison of convective heat transfer of turbulent nanofluid flow through helical and conical coiled tubes

Application of nanofluid and coiled tubes are two passive methods for increasing the heat transfer. In the present study, the turbulent flows of water and nanofluid in coiled tubes heat exchanger were numerically studied. CuO-water nanofluid containing 1 vol% copper oxide nanoparticles was used and single-phase approach was considered for nanofluid flow. The effect of different geometrical para...
